Application and advantage analysis of copper enameled wire

Copper enameled wire has a very wide range of applications and can be used as a carrier for communication signal transmission, inductance. The production of coils such as audio is also used in transformers and welding machines. It has great applicability and market prospects in various aspects such as busbars.​

1. Precautions for the use of copper enameled wire 1. When wiring copper enameled wires, pay attention to the use of copper terminals.​ 2. Avoid using sharp objects during the installation of the twisted coil. If it is too sharp, the copper layer on the surface of the cable will be scratched, which will affect the use effect. The twist ring is best to be installed once, and the number of repeated installations should not exceed 3 times. Excessive manipulation Enameled wires  can cause the monofilament to break.​ 3. After the copper enameled wire terminal is connected, the terminal is sealed with solder, and both ends of the conductor connection in the middle section must be welded.​ Second, copper enameled wire transportation precautions 1. Ensure that the wires and cables will not collide with each other during transportation, causing surface damage.​ 2. The cable is transported in the form of a cable reel, and the end of the cable should be sealed. And the cable reel cannot lay flat during transportation.​ 3. The transportation environment and storage environment should ensure that there is no sunlight and moisture contact.​ 3. Advantages: 1. Copper enameled wire has the advantages of high resistivity and light weight, which can reduce the AC resistance.​ 2. The copper enameled wire is completely covered by copper on the surface of aluminum through metallurgy. As we all know, the chemical properties of aluminum are relatively active, and it is easy to be oxidized by water and oxygen to produce aluminum oxide, and aluminum oxide will cause safety hazards such as poor cable contact and burnt wire heads. Copper-clad aluminum cables avoid these hidden dangers.​ 3. The cost of copper enameled wire is low. Compared with pure copper core cables, copper clad aluminum cables can save nearly 40% of the cost, and at the same time bring about a 40% weight reduction advantage.​ 4. Copper enameled wire can meet various shapes and design applications of industrial cables, and the same weldability as pure copper can greatly facilitate industrial production.​ Four, quality identification skills: There are three identification techniques for copper enameled wire, appearance identification method, chemical principle method and physical principle method: 1. Appearance identification: The copper-clad aluminum cable is generally a flexible wire composed of multiple aluminum wires. The central part of the aluminum wire can be clearly seen on the cross-section of the cable, which is generally white.​ 2. Chemical principle: Take a small piece of wire and cable and burn it with a lighter. Since the wire is an aluminum wire wrapped with copper, and the melting point of aluminum is lower than that of copper, the wire will soften and sag without burning, which means that the material is copper enameled wire.​ 3. Scrape the surface of the copper enameled wire with a knife or other sharp tools. If it is copper enameled wire, it will produce white snowflakes.

Enameled wire welding and paint stripping

The first one: The paint stripping method of aluminum enameled wire is of course scraping the paint with a blade. The wire has not become brittle, but the efficiency is too low, and it is only suitable for the stripping of large wires, and the wire with a diameter of less than 0.5mm is not suitable, because the thin wire is very easy to be scratched, and it is constantly damaged by the scraper, and the toughness is greatly changed. Poor, not suitable for large-scale operations, in addition, after the aluminum enameled wire is scraped, the surface will have burrs, which is not conducive to welding.

The second type: paint stripping of aluminum enameled wire, let's talk about centrifugal knife, this is said to be a kind of paint stripping equipment first introduced in Germany, it uses 3 high-speed rotating knives to peel off the paint of aluminum enameled wire directly, the efficiency is good . This paint stripping method is the same as hand scraping paint, and it is only suitable for stripping paint of large lines. We all know that the physical properties of aluminum are soft and poor in toughness. It is only half that of copper. When using a centrifugal knife, it is easy to be twisted into a rope and broken directly. If the diameter of the aluminum enameled wire you use is 1.5 Below MM, the centrifugal knife is not suitable for you. Even if it is not directly broken, it will be twisted almost ten times. If you use aluminum enameled wire with a smaller diameter, basically don't consider this kind of removal. The paint removal method is not suitable for most motor manufacturers, because the diameter of the aluminum enameled wires used by motor manufacturers is relatively small. In addition, the centrifugal knife will also peel off a layer of aluminum wire when stripping the paint, and the diameter of the aluminum enameled wire will generally become smaller by dozens of wires or larger. This method may not be used for customers with higher requirements.

The third type: the grinding wheel of the aluminum enameled wire, whether you use a steel wire wheel or a fiber wheel, during the process of the paint on the aluminum enameled wire being worn off, the temperature of the aluminum wire will increase rapidly with the high-speed friction, accompanied by With the high-speed air flow, the surface of the aluminum wire is rapidly oxidized, and it is difficult to handle after being oxidized. In addition, due to the different materials of the grinding wheels, generally speaking, the aluminum enameled wire polished by the steel wire wheel turns yellow, and the aluminum enameled wire polished by the fiber wheel turns gray or black. It is not the silvery white of aluminum itself. After the thick wire is ground by the grinding wheel, the degree of oxidation is small, and the silvery white can still be seen. So, if the wire your company is using now is relatively thick, you can choose this method, if it is a thin wire, this method is not suitable.

Fourth: The paint stripping method of aluminum enameled wire is to use paint stripper. I believe many people have used this product. I also believe that many people can't stand its paint stripping efficiency for a long time. The speed of stripping 130 lines is acceptable. , in about a minute, you have to wait for the 150 line, you have to wait hard for the 180 line, and you don't have to wait for the 220 line, this product is more harmful to the aluminum of the aluminum enameled wire Small, in general, it is a better way to use paint stripping powder to strip paint. Many factories make special molds, and a large number of aluminum enameled wires soaked in paint stripper are placed on a fixed shelf to wait for the paint stripper to react, and the efficiency is OK. . But for high-temperature lines, the paint stripping of various manufacturers is basically useless now, and the paint will not come off no matter how long it takes, so this method is not suitable for high-temperature lines. In addition, by the way, paint strippers are generally alkaline, aluminum is an amphoteric metal, acid can corrode it, and alkali can also, so remind friends who are using paint strippers now to use after you have finished stripping paint Be sure to rinse with clean water (or alcohol) (preferably using an ultrasonic cleaning machine). The paint remover is easier to dissolve in water or alcohol. Just rinse it a little. Be careful that your solder joint is corroded by the paint remover.

Making of My Studio Desk

Well, I’ll start by introducing myself, since this is my first post and all. My name is Sabina Kennedy, and I am an artist living in Phoenix Arizona. I’m currently finishing my BFA in sculpture at Arizona State University and I have no idea what I want to do when I grow up. 

I like to make jewelry with non-ferrous metals, like silver, copper, brass. But I also enjoy making a lot of things, like welding steel, and drawing and painting, and embroidery. I’m young as frick though, so I have some time to figure it out. I currently work at a flower shop, Camelback Flowershop to be precise. It’s a really nice place. Ive only been there for about a month, but I like it a lot. I want to one day do the designing of the floral arrangements, but that comes with time.

onto the desk. In my final sculpture class the assignment was to make a tool that would help us with developing our studio. I’m fortunate enough to have a studio space already, that’s frankly a mess, but very cute and full of plants and art supplies. I had a desk that someone made for me a while back, but after moving a couple of times, the legs weren’t firmly attached anymore, and therefore wobbled any time I would sand an object. I decided that it needed a re-vamp

Here it is before I started working on it, all set up at my studio space in the ASU sculpture room. It was a pretty table, nice wood, nice colors, but just not stable, everything was attached using bolts underneath, and nothing was measured consistently. 

I took the top off of the legs, because it’s a really thick, sturdy, high quality piece of wood, and the legs went to the scrap bin. The wood on those was also really nice, but I had to suppress my Taurian urge to collect and keep everything and let them go. 

I decided to use steel for the base of the table. It’s sturdy, fairly inexpensive, and allowed for the design that I was looking for. I did a lot of planning as to the size of everything and how I wanted the design to be. I chose something fairly simple, offering stability, but not being too bulky. I chose 1″ 16ga square tube for the base and got to work. 

  I got all of my material pre-cut at the metal supply store. My first step was to measure everything, and drill holes into the appropriate tube. These holes would be how I attach the base to the wooden top at the end of the process. 

I chose to MIG weld everything together, because it’s the easiest, and honestly it’s so much fun. After this project I want to weld EVERYTHING. The design is simple, it’s basically a three dimensional rectangle, like the ones that you learn about in geometry class. This rectangle is missing the bottom front line however, to allow for my work chair to easily pass under the desk. After getting everything all welded up, I had to sand the piece, to give it some tooth and clean the grease off.

 I then used some Rustoleum spray paint to give this baby the life I was looking for. I had to use plastic and tape to make sure each section wasn’t contaminated by the next. I finished everything with a layer of enamel gloss lacquer, to seal the paint and make sure everything stays on for a long time, also to give everything an overall finish.

I’m obsessed with the colors. They’re very fun and cute and will add some nice color to my studio space. I did a bad job about making a mess on the sculpture dock, but hey, it’s my last semester, I need to leave my mark somewhere right? All while I was working on the base, waiting for the paint to dry and such, I was working on the wooden top.

I took the back pieces off of the big piece of wood, I was really lucky that the person who made me the desk originally just screwed everything together. I then sanded the top to a smooth 220 and made sure everything was nice and clean.

oooo yessss so velvety and smooth!

I finished the top with a semi-gloss polyurethane coating. I didn’t really know how it worked at first, so I used an entire can of the stuff before realizing that I had to sand the furs that get stiff on the wood once the first coat goes down. So I got another can, a piece of 220 sand paper and an air hose and brushed off the rough bits. I put two more layers of the poly on the top, just because it was looking so pretty, and now it’s perfect. 

THAT POLY LOOKING SO GOOD!

I’m really happy with how the poly turned out. it’s looking real clean, and I love the semi-gloss finish. It gives it a nice shine without being too much.

The next step in the process was to put it all together. I pre drilled holes for the hardware I bought before finishing the top, lining everything up with the holes I drilled into the base at the beginning. 

Nothing too fancy, just some half inch washers and some bolts with a hexagonal head that I’m sure have a specific name that i’m not sure of. But yeah, after I screwed everything in, this baby was done. 

Here’s a picture of the table all put together. It’s still in my studio at school right now, probably coming home within the next month or so. 

Back to the gist of the project, It was to create something that would develop our studios. I originally wanted to make a jewelers bench, but the more I thought about it the more I realized that I wasn’t sure if I wanted to be a jeweler for the rest of my life. I changed my plan to a simple table with add ons. The next step will be to make an extender that clamps onto the table top and has a bench pin for more comfort when cutting sheets of metal out with my hand saw. I also want to make a little rolling cart that holds my hammers and wire spools. Right now everything Is kind of mish-mashed around and it would be really nice to have everything all organized together. 

The next part of the project hasn’t started yet, but once it does I’m sure I’ll do a progress post. I also want to show you guys my desk in my studio, with all of my beautiful plants and natural, Arizona sunlight. 

The whole process of making this table was a lot of fun. It definitely makes me think that I will spend my adult life making things for people to use. I love art, I love making art, but really I just love making. I was born to be a maker, but of what, I’m not sure yet.
