Understand the cause of Control Cable Wire failure

Five Control Cable Wire Failure Modes

1. Conductor failure Open Conductor - The conductor may break or break, resulting in a loss of continuity. Causes can include repeated bending in a narrow bend radius or ticking motion, incorrect or too tight bend radius, or extreme tension on the cable.

High resistance of conductors - Stranded conductors will most likely initially see a single strand break before the conductor is cut. As a single strand breaks, the resistance of the conductor increases. This can lead to two possible failure modes: 1) the conductor strands will continue to break until a complete break occurs, or 2) the higher resistance will begin to generate heat and eventually overheat, causing localized burning points to break the conductor.   2. Insulation failure Cracks/Perforations - Types of insulation failures may include cracks or perforations in the insulation. Cracks in insulation can be caused by constant bending over narrow radii. The insulating material becomes fatigued and eventually fails. Perforation of the insulation can occur if the conductor strands begin to break or cut and perforate the insulation wall.

3. Shield fault Foil Guards - Foil guards tend to break down over time when subjected to repeated bending/bending movements. Foil shields started to crack, eliminating their use in cables.

Copper Braided Shields - Copper braided shields can become mechanically fatigued, especially when placed under twisting or twist-type motion.

4. Jacket failure The jacket protects the inner conductor and cable assembly from the external environment. It is subject to the greatest abuse by mechanical, chemical and weather influences.

cable expansion Cracking/Expansion - Exposure to certain oils, chemicals or fluids may cause the jacket material to react negatively. Depending on the chemical, this can cause the sheath to swell and become soft and tear easily, or hard and brittle leading to cracking.

Wear - When the outer jacket wears from exposing the cable core, the outer jacket fails due to wear. This type of failure occurs when the cable is used in an application that wears down the cable. This can happen if the cable is dragged across the ground, in an application that constantly rubs against the cable, or if it is improperly installed on the equipment.

Cuts/Punctures - Bumping or contact with sharp objects can cause cuts to the jacket. Small cuts that appear only on the surface of the jacket usually do not affect cable performance. Cuts that impair the performance of the jacket or penetrate into the shield or cable core are reasons to repair or replace the cable.

5. Electrical failure Open Circuit or Loss of Continuity - An open circuit (or loss of continuity) of a conductor will result in loss of power or signal data.

Short Circuit - A short circuit can occur if a conductor strand breaks and penetrates the insulating wall and comes into contact with the shield or other strands of the broken conductor. Conductor-to-conductor or conductor-to-shield shorts may occur. Depending on the location and application of the short, this can result in loss of signal or data, or transient overcurrent resulting in conductor or cable damage.

Shielding Loss/EMI-RFI Issues - Cables may be more susceptible to EMI/RFI noise issues if foil and/or braided shields are damaged. This may result in data loss or corruption.

Current Overloading - If the ampacity is not handled properly, the cable can overheat at the conductors. This can lead to extreme heat build-up that compromises the integrity of the insulation and sheathing materials. In extreme cases, cables can burn and become flammable.

What are the applications of carbon fiber in cables?

Aluminum Conductor Composite Core (ACCC) cable is a replacement product of traditional Aluminum Conductor Steel Reinforced (ACSR) cable. As early as the 1990s, Japan began to develop ACCC cables. Afterwards, the United States Composite Technology Corporation (Composite Technology Corporation, CTC) also successfully developed and became a supplier of ACCC. Fujian Power Grid and Tianjin Power Grid have already erected and operated the new conductor, and achieved remarkable results. Jiangsu Far East Group developed ACCC cables in 2006 and established production lines. At present, there are many ACCC cable production lines in China.

Compared with ACSR cable, ACCC cable has the following advantages

1) Light weight and low density: the density of the carbon fiber composite core is only 1.90g/cm3, and that of the steel core is 7.8g/cm3. The former is much lighter than the latter, so the distance between poles and towers can be increased, and the number of poles and towers can be reduced by about 16%, which also reduces the occupied area and saves investment. At the same time, the density is small, which increases the safety.

2) High strength and high breaking force: the tensile strength of ACCC is about 2399MPa, which is 1.97 times that of ordinary steel wire and 1.7 times that of high-strength steel. At the same time, the test results show that the destructive power of the former is about 30% higher than that of the latter. The strength of AC-CC is high, and the external force is mainly carried by the carbon fiber composite core. The aluminum stranded wire hardly bears external force; thus greatly improving the service life.

3) High electrical conductivity and large ampacity: Under the same diameter conditions, the cross-sectional area of aluminum stranded wire in ACCC is 1.29 times that of conventional ACSR, and the ampacity is increased by about 29%. This is based on the following reasons: First, the specific strength of the carbon fiber composite core is greater than that of the steel core, so the diameter of the mandrel can be made thinner, thereby accommodating more aluminum wires and a larger conductive cross-sectional area; second, the cross-sectional shape of the ACCC aluminum strand It is trapezoidal, while the ACSR aluminum wire is circular in cross section. The former is easy to be compact and densely packed, and can accommodate more aluminum wires, thereby increasing the conductive cross-sectional area; the third is that the ACCC outer aluminum wire adopts annealed aluminum wire with a conductivity of 64% IACS, which is comparable to that of hard aluminum wire with 61% IACS. Increased by 3.3%.

4) Small line loss: carbon fiber composite material is a non-magnetic material. When the wire passes through alternating current, there will be no hysteresis loss and eddy current loss, showing a small alternating current resistance. -Generally speaking, the transmission loss can be reduced by about 6%. At the same time, because ACCC uses trapezoidal aluminum stranded wire, its surface is smoother than that of ACSR round aluminum wire, which reduces the surface roughness value, thereby increasing the corona initial point pressure of the wire and reducing corona loss.

5) Corrosion resistance and long service life: the carbon fiber composite mandrel avoids the electrochemical corrosion between the aluminum wire and the core steel wire when the steel core is energized, so that the aluminum wire can be used for a long time without aging. At the same time, the outer layer of the carbon fiber composite mandrel is an insulating glass fiber composite layer, and some of them are coated with polytetrafluoroethylene film or insulating coating on the outer layer of GFRP, so that the aluminum wire and the mandrel are completely insulated, and there is no gap between the two. There is a contact potential difference, which protects the aluminum wire from electric corrosion and prolongs the service life. Figure 9-5 shows the schematic cross-sectional structure of ACCC.

6) The thermal expansion coefficient is small: the thermal expansion coefficient of ACCC is 1.6x10-6/9C, and that of ACSR is 11.5x10-*7C, and there is a big difference between the two. The condition test shows that when the temperature rises from 21.6C to 186C, the sag of the ACSR wire increases from 236mm to 1422mm, an increase of about 5 times, while the ACCC wire only increases from 198mm to 312mm, which is only about 0.57 times. Apparently, the change in sag of ACCC is only 9.6% of that of ACSR. Therefore, ACCC cables are much better than ACSR in adapting to environmental temperature changes such as day and night temperature differences, winter and summer temperature differences, and are a safe new generation of high-end products. In addition, the weight of ACCC is only 70%~80% of ACSR, which is convenient for transportation and good in operability.

Industrial Connectors: The Basics

Need to upgrade or replace a set of industrial connectors but you’re not sure what you need to replace? This short primer will help clear up some of the basics associated with these electrical connectors.

What Are Industrial Connectors? Industrial connectors are used to provide an electrical connection between industrial system components, or between power mains and equipment, often in the presence of a variety of challenges in industrial environments.

Industrial connectors have a female end called a jack and a male end called a plug and are available in a wide range of configurations and ratings that will impact their suitability given the environmental conditions in a given location.

Pin Configuration Many industrial electrical connectors have pins, and come in configurations ranging from 3-pin to 24-pin connectors. These pins provide a secure electrical connector for power, signal, or data transmission.

The reason for these different configurations is that each contact may have a different use or property and the complexity of the circuit may require that each contact has its own pin.

Electrical connectors are often (but not always) made of conductive metals such as copper alloy and are sometimes gold-plated to ensure a quality electrical connection as well as to resist corrosion.

Amp and Voltage Rating The amp rating, or ampacity, of a cable, is the maximum current the connector can safely carry under continuous use without the risk of exceeding its temperature rating and overheating.

Voltage rating is similar but not quite identical. It refers to the maximum voltage load the connector can tolerate. Exceeding the voltage rating can cause the premature failure of electrical equipment and can cause cables and connectors to overheat, increasing the risk of fire.

Voltage is the product of current and resistance, so while these two factors are interrelated they are not identical; nonetheless, it is necessary to use only electrical connectors and cables rated according to the voltage and ampacity of the function.

What Traits Are Important in Industrial Connectors? Many industrial connectors are expressly manufactured to tolerate a wide range of environmental conditions.

For instance, if an occupational hazard of your industry is exposure to oil, salt water, or other liquids, then corrosion-resistance and waterproof connections are critical.

Exposure to high heat and pressure is also common in industrial settings, and consequently, many industrial electrical connector housings are resistant to these as well.

Moreover, some electrical connectors are rated to deliver a high degree of protection against EMI, or electromagnetic interference, which can scramble signal transmissions or entirely incapacitate a circuit.

Application characteristics of GWH fire retardant sleeve in power cable industry

GWH fire retardant sleeve can be used for fire protection of power and telecommunication cables. It is of great significance to eliminate hidden dangers and ensure the normal operation of transmission and distribution and telecommunication lines. GWH fireproof and flame retardant sleeve is a new product for power and telecommunication cables. It has the advantages of flame retardancy, insulation and operability. It uses low smoke and halogen-free, and does not affect the cable ampacity during cable operation. As the GWH fire-retardant sleeve is used to wrap on the surface of the cable sheath, when a fire occurs, it can quickly form an oxygen resistant and heat-insulating carbonized layer, effectively preventing the burning of the cable. GWH fire retardant sleeve can be widely used in high and low voltage power supply lines, especially for cable fire protection in substations, subways, tunnels, chemical industry, coal mines, large buildings and other environments, and can also be applied to other parts with fire protection requirements.

How to choose the correct cable based on the ampacity factor?

Electrical wire and cable systems are a must for any industrial application. And it's not just about choosing the right cable for the job - it's about understanding your environment and its capabilities.

Lack of knowledge about the cable we are using can cause the cabling to fail and the entire system to shut down, leading to costly downtime.

Here we will talk about the factors that influence ampacity and some basic information that you can use to better understand the capacity of your in-plant wiring and reach your full potential in each application.

Factors that determine the ampacity of a cable

Ampacity is the maximum current, measured in amps, that a conductor can continuously carry under normal use conditions without exceeding its temperature rating. It can also be described as the current carrying capacity.

This factor depends on:

·        Conductor size, gauge and material

·        Insulation material

·        Number of conductors

·        Room temperature

·        Installations

·        Distance between point to point of connection

What to do when the cable temperature gets too high?

If this happens, it is necessary to apply correction factors to the ampacity value of the cable. As the ambient temperature levels off, the ampacity values ​​will decrease.

A correction factor is a multiplier that is calculated and used to adjust the amount of energy pushed through a cable, based on the amount of heat that is radiated when the cable conducts energy.

The NFPA National Electrical Code table for Ambient Temperature Correction Factors provides the correct correction factor based on the ambient temperature rating of your cable. If a cable is used without applying the correction factor, it can overheat and fail.

Applications that impact ampacity values

Some uses of the cable that can cause the ampacity to vary are as follows:

·        Cable installed on reels with multiple layers of cable requires a correction factor. As the number of cable layers increases, the ampacity value will decrease.

·        Correction factors can be applied to multiple cables running in cable trays, depending on the spacing between the cables and the type of tray used.

·        Installation on roofs with direct sunlight requires correction factors to adjust cable ampacities.

Types of Cable Typically Used in Cable Tray

The purpose of a cable tray system is to support, route, and protect cable as part of the cable management system. Through NEMA and the Cable Tray Institute numerous articles, standards, and other general guidance can be found regarding the proper use and installation of cable tray systems.

The cable tray system is only one component of the cable management system. Another important component is obviously the cable. Therefore, it is also important to understand how to properly apply and install the cables in a cable tray system. To that end, this Bulletin is intended to discuss the types of cables most frequently used in cable trays and the wiring methods permitted in cable trays under the National Electric Code (NEC) NFPA 70.

In general, tray-rated cables are quality products that have been tested to withstand the rigors of severe environments. They are protected by either a plastic Jacket or metal Armor over individual conductor insulations. They can be rated for outdoor, indoor, corrosive areas, hazardous locations, or high electrical noise areas. They should be UL listed indicating they have been tested for ratings relative to flammability resistance, mechanical resistance, and temperature limitations. Many cable tray-rated cables include a crush and impact test as part of the listing and are rated as exposure rated (ER). ER cable is allowed to leave the cable tray for distances up to six feet, as long as it is supported and secured.

In many cases there is more than one type of cable for a particular application, for instance, both cables rated as tray cable (TC) and cables rated as metal-clad (MC) can be used for 600- volt motor power cables. In all instances, cables utilized within a cable tray system should be UL listed and marked as cable tray rated.

The types of cables, allowed in cable trays, and the wiring methods permitted in cable trays can be found in NEC Section 392.10 (A). This Section also lists various corresponding NEC Articles which describe the conditions of use and installation requirements for a particular class or type of cable. Additional considerations such as fill capacity, allowable ampacity, cable splicing within trays, and securing and supporting cables are addressed in Article 392. Users should be familiar with all these Articles and check the manufacturer’s specifications, to verify selected cables meet all application requirements and NEC requirements.

 The most frequently used cable tray are:

 Tray Cable – type TC

Power Limited Tray Cable – type PLTC

Instrumentation Tray Cable – type ITC
