Enameled Winding Wire - Different Types

Enameled winding wire & Enameled aluminium and copper wire are both a very reliable wire made from copper, aluminium or both. They both require an extra process called dipping to make sure that they are well protected and tightly fitted so that there are no gaps between wires. This is because, while the binding is tight and secure, if there are gaps, the wire might slip out of its wrapping. Enamel is the substance that gives the copper winding its shiny finish.

Copper wire thermal classic and Enameled winding wire both have similar characteristics and uses. The main difference lies in the metal used to coat the wires. Enameled copper wire & Enameled aluminium wire is a flat wire coated with a layer of enamel, which prevents the wire surfaces from becoming in a hot circuit. Magnetic flux is applied to the enameled wire before it is wound into strands.

Both of these types of wire are very good conductors of electricity as electricity moves through them very easily. The attraction-repulsion characteristic of the metal prevents them from being damaged by friction and keeps them safe. They are safe to use even in power surges and extreme weather conditions as well. However, the enameled wire is slightly more expensive than the aluminium magnet wire due to the additional cost of coating. Although it is more expensive, it offers a higher quality product to its customers.

Enameled and nichrome wire both are available in different varieties. These varieties are: pure enameled, semi-precious and plated varieties. In order to achieve a specific wire shape, a special solution is applied to the metal while it is being formed. This solution is called embossing.

An enameled aluminum magnet wire is one that has been pre-manufactured and manufactured using enamel coating. This type of wire can be wound on itself very easily without any wrapping or tape. The flat aluminium wire is known to have high electrical conductivity levels and is used for various industrial applications such as connecting electrical wires in electronic panels. This wire is also found to be a good conductor of heat and it can also take a lot of stress.

The flat aluminium magnetic wire is another type of wire that can be found out in the market today. These are known to have low electrical conductivity levels and they are normally used in conjunction with copper enamelled winding wire. The enameled wire will then be coated with tin-plated steel wire. This gives the wire enough strength so that it can withstand a high degree of temperature class. Another major factor used in manufacturing these wire is the presence of an electrochemical gradient.

The third type of wire enamels market is that of the pure copper wire. Pure copper wire will have a single crystalline wafer along with an electrochemical gradient. The main purpose of using this type of wire is to provide electricity through electrical conductors. When copper wire is coated with nickel, it will become capable of dealing with extremely high temperatures. Nickel has the ability to increase the electrical resistance that is found in the bare copper wires.

Flat aluminium wire and pure copper wires can be found in different places in the market. When choosing the right kind of wire, it is necessary that the buyer gets the correct specifications so that the wire can perform its best. All types of enamels in the market are known to be useful in various ways. However, it is essential to choose the type of wire according to the type of function that the wire is meant for.

A Brief History of Enameled Aluminum Wire

Enameled aluminum wire is one of several varieties of aluminum wire that is highly conductive and flexible. These features make aluminum an excellent choice for many applications where it performs a function that copper can not. In addition, aluminum has a lower cost per unit than copper. Aluminum wire can be used for high frequency applications, such as communications systems, home appliances, medical equipment, computer and laptop accessories, lighting fixtures, auto accessories, Enamelled Copper Wire motorcycle and automotive accessories, wiring in automobiles and boats, marine and construction equipment, and personal tools. Aluminum is also a good choice because it is stronger than copper and more durable.

Because aluminum wire can be formed into flat sheets, it offers the ability to be woven, rolled or blow molded into various shapes and sizes. The higher the voltage and current in use, the larger the diameter of the wire, so larger diameter aluminum enameled wires are recommended for high voltage applications. When the resistance to electricity is the same, the aluminum wire's resistance is nearly equal to that of copper, which makes the wire almost as responsive as copper. Some manufacturers prefer to use aluminum enameled wires in applications requiring larger diameter because it increases the strength and decreases the probability of breakage.

Another advantage to using aluminum enameled wires in applications requiring high voltage is that they are non-conductive. Many metals have some amount of conductivity, including pure copper, silver, tin, and gold. However, some metals are completely non-coincident with electricity, such as nickel. Since aluminum wire does not contain any electrical charge, it is safe to handle and work with even in hazardous environments.

Aluminum wire has another significant advantage when used in thermal class systems. The thermal class system recognizes a particular resistance to heat such as "reduced" or "zero" amperage, which can help prevent short-circuits and excessive heat formation during arc production. Many thermal class systems also include a reference number, which identifies the wire's thermal class. If the wire should be used in a different thermal class, it should be identified so that it can be properly matched to the appropriate wire.

Some manufacturers also create an Enameled Copper Wire, which is derived from pure copper but has the added benefit of not containing any copper components. An example of an Enameled Copper Wire is manufactured by Silvermetals, Inc., and is often used to connect electronic components to their mounting surfaces. Similar to an aluminum wire, enameled copper wire has the ability to resist corrosion, which provides added durability. Unlike most other copper wires, this wire has a polished finish that makes it highly attractive for a variety of mounting applications. Some manufacturers also customize this wire to meet specific application requirements.

Although an Enameled Copper Wire is almost identical to a pure copper wire, they are slightly less durable and typically offer a lower temperature operating temperature. The most common type of Enameled Aluminum Wire is usually seen in applications requiring a premium quality wire with added protection. Many times the manufacturer uses a combination of copper and aluminum to achieve the protection desired. The application of an ionic bonding agent may provide even greater corrosion protection. Either way, an aluminum enameled circuit wire will stand up to the wear and tear that is a part of electronics manufacturing.

After all, some are welded and very thick, while others are extremely thin and plastic like. The question is, why would you want either one? I will explain some of the most common reasons why a person might opt to go with aluminum instead of any other material.

First off, this type of wire has been proven to be extremely durable for various applications in the home, industry as a whole. The proof of this is found in the fact that aluminum is able to withstand tremendous amounts of heat. This is important because magnetic power generation is done by attracting or repel a magnetic field. Heat is something that a lot of people don't think too much about, but which can potentially ruin the entire process if it is not taken care of properly.

Another thing about aluminum magnet wires that I want to go over with you is the fact that it can be crafted into different shapes and sizes. You might be wondering what exactly shapes these magnets can take. Well, you'll be surprised! Some of these can be as small as a quarter or can stretch out to be twice the width of a standard paper.

The benefits to these aluminum magnet wires are endless. For instance, they can be crafted into different configurations to handle anything that may come their way. This can range from a small hand sized object all the way up to a large object. Also, this is a form of electromagnetic energy so it can not only provide you with power, but it can also help to clean and prevent the spread of disease. This is important because the disease is spread through the air and by the touch of hands.

One thing that I want to make sure you keep in mind with aluminum magnet wires is that they are an excellent choice. However, there are a few things that you need to keep in mind before you start shopping for these wires. For example, you want to make sure that you get them in the right size and in the right gauge. You can either ask a local electrical contractor where the wire is manufactured or you can do some research online.

These magnets can be found in most places such as your local hardware store. However, if you don't have one of these, then you can find plenty of suppliers online. You can get these products from numerous websites, so you shouldn't have any problems with finding a great supplier. Aluminum Wire is certainly a new and emerging technology that will revolutionize the way we do everything.

Aluminum Magnet Wire Factory

Magnet wire is manufactured using two-conductor magnet wire that consists of a core conductor made of one or more materials like aluminum, tin, steel or other alloyed alloys. The thickness of such wire gauges dictates the electrical capability and strength of the magnetic field around it. The weaker the magnet, the thicker the wire gauges will be and the smaller the gauge can be wound around the magnet to produce a strong magnetic field. A magnet having a higher coercivity will produce a much stronger electromagnetic field, however, a weak magnet will only allow a small force to be exerted on it before it disintegrates into a plasma state.

Aluminum Wire Gauges: These gauges are very thin and are often coated inside with an enamel coating to maintain their rigidity and resistance to electrostatic attraction and repulsion. The electrical conductivity and strength of these wires are quite high when they are wound tightly. This type of wire is excellent for applications in space travel, electronics and magnetic power.

This type of aluminum magnet wire is also used in medical applications. In fact, magnetic therapy has been around for more than a hundred years. Magnetic therapy is a great alternative to harmful and expensive magnets and expensive medical equipment. Therefore, if you are looking for a high performance and long-lasting magnet wire that are made of the strongest alloy that is available, the aluminum magnet wire factory is the right place for you to be.

What are the basic properties of the plastic for magnet wire

magnet wire1, cold resistance

The ability of magnet wire plastic to maintain certain physical and mechanical properties at low temperatures is called the cold resistance of plastics. It is often expressed by the following cold-resistant temperature.

1) Low temperature embrittlement temperature: It is the temperature at which 50% of the samples are damaged when the plastic is subjected to a specific impact load at a low temperature.

2) Low temperature half-folding temperature: it is the temperature at which the plastic sample is about to rupture when it is bent 180o.

3) Low-temperature impact compression temperature: it is the temperature at which the plastic sample is impacted and compressed by a hammer with a certain energy and speed at a low temperature to make the rupture rate reach 50%.

2, flame resistance

Flame resistance refers to the ability of plastics to resist flame burning. Generally, plastics will burn after contacting the flame. After the flame is removed, the flame extension varies with different types of plastics, so the flame resistance performance is also different.

3, heat aging resistance

In the process of plastic processing and use, the performance of the plastic deteriorates due to heat. This phenomenon is called thermal aging. The ability of plastics to resist heat aging is called heat aging resistance. The accelerated thermal aging test at high temperature is used to determine the retention rate of plastic properties (mechanical properties or electrical properties) after aging to measure the thermal aging resistance of plastics.

4, weather resistance

Plastics are used under atmospheric conditions, and are affected by harsh natural conditions such as sunlight, rain, wind, and air pollution. The deterioration of plastic performance is called atmospheric aging. The ability of plastics to resist atmospheric aging is called the weather resistance of plastics.

How to convert the diameter of aluminum enameled wire and copper enameled wire?

If an enameled wire of a burnt-out motor is an aluminum wire, how to convert it to a copper enameled wire sold in the market? Let Huzhou Fuda Electrical Technology Co.,Ltd share with you some conversions in this regard:

If the enameled aluminum wire is changed to enameled copper wire, it can be converted according to the following formula:

D copper = (ρ copper / ρ aluminum) 1/2 * D aluminum

D copper: copper wire diameter

D aluminum: aluminum wire diameter

ρAluminum: the resistivity of aluminum, take 1/35.5

ρcopper: copper resistivity, take 1/58

Note: 1/2 in the formula refers to square root, not multiplication.

For example, when using 0.51mm aluminum enameled wire and using copper wire instead, the diameter of the copper wire is D copper=(35.5/58)1/2*0.51=0.61211/2*0.4=0.7823*0.51=0.4

That is, after 0.51㎜ aluminum enameled wire is changed to copper enameled wire, 0.40㎜ copper wire should be used instead.

Advantages of copper clad aluminum enameled wire compared to copper enameled wire

Copper-clad aluminum enameled wire and copper enameled wire, the two products are only two words different, but their performances are very different. We all know that copper enameled wire is a wire made of copper material, so what help does the upgrade of copper-clad aluminum enameled wire on its original basis bring us? Let us take a look.

First of all, we have to understand what is the inner conductor of copper-clad aluminum enameled wire, which is the raw material of copper-clad aluminum, and what is copper-clad aluminum. Copper-clad aluminum is a new type of electromagnetic wire, which separates the excellent conductivity of copper very well And aluminum has the advantage of light weight, and its characteristics are between copper and aluminum. Copper-clad aluminum enameled wire is generally used in transformers, inductive electromagnetic coils, acoustic coils, demagnetizing coils and other aspects of electromagnetic wire. It has high DC resistivity, light weight and good solderability. But at the same time, there are several aspects that need attention.

Due to the low cost, most companies use copper-clad aluminum enameled wire in power transmission and transformers. In practice, copper-clad aluminum enameled wire cannot be used in many areas. The electrical resistance of copper-clad aluminum enameled wire is higher than that of copper wire. The problem of temperature rise is worthy of attention. In addition, the aluminum wire is easy to oxidize, which will further increase the resistance. During the application, it is necessary to take measures to avoid oxidation to prevent the formation of losses. Copper-clad aluminum enameled wire can be used for signal transmission, but it will cause great problems in power transmission and reduce its product life. When using it, pay attention to maintaining the cut surface of the enameled wire, avoid aluminum oxidation, and ensure the effective separation of aluminum and copper, which can also extend the service life. The most demanding attention is the reliability of this new type of metallurgical separation in the long-term use process. In the process of thermal expansion and contraction, the separation of copper and aluminum can stand the test. There is no real argument in the industry.

In any case, copper-clad aluminum enameled wire still has many advantages such as low cost, light weight, poor conductivity and so on. Reasonable use and protection can extend the service life and greatly reduce the cost.

Many people think that the winding of finished copper enameled wire is only carried out at will, but in fact, this requires skill. This involves the three relationships of wire diameter, tension and speed.

Fuda Electrical Technology point that tension of the copper enameled wire has different safe tension data according to different wire diameters. For specific data, you can consult the copper enameled wire manufacturer for consultation, or you can think about it according to your product needs, and do a solid inspection of the resistance request and the size of the copper enameled wire package and the deformation of the skeleton. After the level reaches the request, use the tension device to stop measuring the force and set the value as the norm. The relationship between wire diameter, tension and speed: the wire diameter is large and the tension is large, the speed is only the length of the product winding the enameled wire per second, if the product diameter is too large, the winding speed is slower, if the product is small, the equipment speed can be faster To control the tension and speed according to the size and wire diameter of the product.

Tips on enameled wire

"3 diligent" of enameled wire

1. Diligent paint film, during production operation, measure once every hour, and correct the zero position before the measurement.

2. Diligently calibrate the cables, check the back and forth cables and the tension tightly, and correct them in time.

3. Look at the surface diligently, and check whether the enameled wire is granular or peeling off during the coating process. If you find out the reason, make corrections.

Enamelled wire is a main variety of winding wire, which is composed of conductor and insulating layer. The bare wire is annealed and softened, then painted and baked multiple times. However, it is not easy to produce a product that meets both standard requirements and customer requirements. After all, it is also affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but we can choose some better through some inspection methods.

What should be paid attention to when enameled wire stripper.

1. Enamel wire stripper does not need to be diluted during use, it can be used directly. In addition, in order to prevent the liquid splash from hurting people, it is necessary to wear a hat, mask, latex gloves during the operation, and then perform the operation.

2. Before using the enameled wire stripping agent, it should be fully stirred, and it should not be poured too quickly into the stripping tank, it needs to be poured slowly.

3. When using, directly immerse the enameled wire in the paint stripping tank and leave it for about 1 minute to take it out.

4. The specific paint removal time needs to be selected according to the thickness and quality of the baking paint.

The common inspection method is mainly salt bath inspection:

A. Enameled wire test length 5m,

B. Put the 5m enameled wire into the salt bath, and connect the two ends of the enameled wire to be tested according to Figure 1.

C. After the positive electrode of the power supply is effectively connected, direct current is 24 volts, and the test is performed according to the leakage current acceptance criteria. If no red liquid appears, the enameled wire salt bath test is qualified; if there is red liquid, there are pinholes, carefully observe the number of pinholes and damage Location and make a record;

D. When the current method exceeds the standard, please use the pinhole method for analysis;

E. After the test, put the power cord back to its original position;

It is necessary to record the leakage current data measured by the current method and the number of pinholes analyzed by the pinhole method. At the same time, the daily water change records should be checked.

Follow the steps to select the high-quality enameled wire myself!

Transport and storage

1. During the transportation and loading and unloading process, the copper-clad aluminum wire and coil should not be damaged. It is strictly prohibited to push the copper-clad aluminum wire reel directly from the car. Cable reels shall not be transported and stored horizontally.

2. Before transporting or rolling the coil, it is necessary to ensure that the copper-clad aluminum coil is stably and tightly wound. When rolling, you need to follow the direction of the arrow on the reel or the winding direction of the wire.

3. After arriving at the scene, the copper clad aluminum wire and its accessories should be checked in time according to the following requirements: (1) The product technical documents are complete. (2) The model, specifications and length of the production line should meet the requirements of the order, and the accessories should be complete. The appearance of the line must not be damaged. (3) Be careful at the sealed end of the pipeline. When there is any doubt about the appearance inspection, the water content should be judged or tested.

4. If the copper-clad aluminum wire and related materials are not installed immediately, they should be stored in a separate category and indicate the type, voltage, specifications and length.

Several market artifacts that affecting the quality of enameled wire

1. Lack of money and people

This concept is not difficult to understand. Small enameled wire production companies are far less wealthy than large enameled wire companies. There is also a great difference in financing abilities. Because of lack of money, small and medium-sized cable production companies directly talk about research and development. Imitation skills. The same, because of lack of money, small cable companies do not have the talent to buy high-tech production equipment, often a backward production equipment can be used for ten or even twenty years! Other, closely related to this, is the same because of small Cables are short of money, which makes it difficult to attract high-skilled personnel and to meet the needs of each other's treatment. Moreover, in small and medium-sized enameled wire production companies, employees have lower salaries than large-scale enameled wire production companies, and the boss's commitment to employees is difficult to achieve in a short period of time, which constitutes a serious loss of personnel.

Therefore, lack of money and people is the crux of the difficulty for small and medium-sized enameled wire companies to advance product quality. Because of lack of money, hardware can't keep up (including employees); because of lack of talents, software can't keep up (including process talent analysis, skills research and development, quality inspection, etc.), and the only entanglement between the two is the only situation Employees are not motivated, creativity is weak, and product quality is difficult to advance.

Second, poor quality concept

When large enameled wire companies are worried about low product quality, small and medium-sized enameled wire companies pay more attention to shopping malls. This is not difficult to understand, it depends on the different moods of small enameled wire production enterprises and large enameled wire production enterprises. When large-scale enameled wire production enterprises sweated out the phenomenon of counterfeiting and inferior brands in the mall, some small cable companies were rushing to work on counterfeiting. It can be seen that the mood of the station is different, and the mood of the quality of the enameled wire is different. The most important point is that for small and medium-sized production companies, whether it is the leadership or the bottom employees, there is a certain error in the knowledge of quality management. They lack the knowledge of quality management control and have some responsibility for the job. shortage. For example, we often see such a phenomenon. Many enameled wire production companies attribute the advancement of product quality to the work of the quality inspection organization. Once the relevant quality organization considers the product quality to be unqualified, these companies often first respond to the quality inspection organization's "I, and then" connected "through various methods.

Others, it is precisely because of this state of mind of the corporate leadership that it is directly conveyed to the relevant quality assurance part that the quality is not up to the quality inspection organization. Even if it does not pass, there are also leadership “activities” and then frustrates quality management. Motivation of personnel. Even under this "misunderstanding", some cable manufacturers have shown that when operators find quality problems in their operations, they not only deal with them improperly, but also keep tabs and conceal them. Workshop managers also pay more attention to output value and sales. Perhaps the quality is ranked second.

Third, pay more attention to immediate interests

Obviously, it is not straightforward to make profits by advancing product quality. The most direct way is to obtain orders and occupy the mall. Therefore, most small and medium-sized enameled wire manufacturers have a greater desire for possession of shopping malls than large cable manufacturers. This is understandable, because once a small cable production company fails to win an order, it may constitute a risk of tightness of the capital chain or even cracking, which will expose the enterprise to a disaster.

Therefore, small enameled wire production companies pay more attention to the "shopping talent" of employees. Whether black cats and white cats can catch mice is a good cat. No matter what method is used, winning orders can be a good sale. Small cable companies are all the same, the difference is the urgency). What kind of situation does this constitute? That is, when small cable manufacturers get orders that are "tight" in time, they often just blindly carry out and negligently check the product quality. And if the shopping mall is in a good condition, and the order is one after another, this situation is particularly significant. The so-called "radish is fast and does not wash the mud". In order to chase the development and seek speed, the quality control often relaxes the requirements and constitutes unqualified product quality . In other cases, even if the quality of the product is too high (it cannot be detected on the surface), such a product is not expected to be used for a long time. In less than three or five years, the stability of the product will be damaged, and serious or even serious disasters will be caused.

Fourth, the environmental factors of the mall

After all, the reasons that affect the quality of enameled wire operations are the environmental factors of the mall. At present, there are many environmental factors of the mall that affect product quality. The most outstanding are disorderly competitions, vicious competitions, and low-price competitions. Because domestic cable operations have fought a price war, there are no advantages for small and medium-sized cable manufacturers. Because the production equipment cannot keep up, the production technology is not advanced, and the shortage of talents, etc., it is difficult to control the production cost. Cut corners, cut corners to save and control costs. In order to reduce the cost, some companies will “shrink” the copper conductor, which accounts for nearly 80% of the raw material cost, greatly reducing the practical cross-sectional area. Some manufacturers use impurity copper in the production, which leads to the unqualified conductor resistance index of 49.6% enameled wire products.

Of course, this is only considered from the perspective of the cable manufacturer, and it is not to be neglected that some customers explicitly require consideration from the "control engineering cost", blindly seeking low prices and neglecting product quality. This point also makes it clear why the domestic cable operation has fallen into a "price war", showing a strange phenomenon that focuses on price but not quality. Others that do not clean the relevant detection parts are not strict enough, showing the phenomenon of "activities" successful in the third point above.

Application fields and precautions of copper-clad aluminium wire

Copper-clad aluminum enameled wire is a new type of electromagnetic wire using copper-clad aluminum material as the inner conductor.

advantage:

Its characteristics are between copper and aluminum, combining the excellent electrical conductivity of copper with the advantages of aluminum's light weight.

Features:

1. DC resistivity: The DC resistivity of copper-clad aluminum wire is about 1.45 times that of pure copper wire; when the resistance is the same, the weight of copper-clad aluminum wire is about 1/2 of that of pure copper wire.

2. Good solderability: Because the copper-clad aluminum wire is concentrically covered with a layer of pure copper, it has the same solderability as pure copper wire without the need for special treatment like aluminum wire; meanwhile, copper The aluminum-clad wire has a thicker copper layer to ensure that the solder performance of the product will not be affected when scraping paint;

3. Light weight: Copper-clad aluminum wire density is 1 / 2.5 of pure copper wire with the same diameter, which is very effective in reducing the weight of the coil; using Shenzhou copper-clad aluminum wire instead of copper wire can save at least 30% of cost.

Application areas:

1. High-frequency transformers and ordinary transformers;

2. Inductance, electromagnetic coil;

3. Motors, including household motors, various micro-motors, and compressors, which have higher environmental requirements;

4. Special electromagnetic wires for audio coils and optical drives;

5. Magnet wire for display deflection coil;

6. Electromagnetic wire for degaussing coil;

Precautions:

1. Copper-clad aluminum enameled wire can be used for signal transmission, but now it is used for power transmission, it is easy to cause problems, and the life of its products will be greatly reduced. In fact, in the use of copper-clad aluminum enameled wire, pay attention to the oxidation protection of the lower side of the enameled wire to ensure the effective combination of copper and aluminum, which can be used for a long time.

2. Copper-clad aluminum wire and copper-clad aluminum enamelled are actually unavailable in many areas, but the fact that many companies use transformers is very worrying. There are two concerns about the use of copper-clad aluminum wire. The specific resistance itself is higher than that of copper of equal section and the problem of temperature rise; the easy oxidation of aluminum wire will further increase the resistance of the wire and prevent oxidation.

3. What is worrying is the combination of copper and aluminum in the copper-clad aluminum wire. The metallurgical combination often said in the industry is truly reliable in the long-term use process, and whether the copper-aluminum bonding ability can Withstand the test, there is no real argument in the industry.
