High temperature cable

High temperature cables are cables made of multi stranded soft copper conductors. Heat resistant and high-temperature wires and cables are generally determined by two needs. The first type is that the ambient temperature of wires and cables is relatively high, and the cables can transmit signals or electrical energy normally under high temperatures for a long time; Another type is power transmission cables, mainly aimed at increasing interception capacity. High temperature cable is a special type of cable that is called a high temperature cable due to its high temperature resistance

The use of high-temperature wires

High temperature wires are mainly used in industries such as communication, automobiles, motors, and construction, such as flexible wires for movement, rubber insulated flexible power cables, high-temperature resistant building wires, automotive wires, aviation wires, locomotive wires, motor and electrical wiring, etc.

Characteristics of high-temperature cables

High temperature cables are made by adding special materials and processing. Compared with traditional cables, high temperature cables have absolute performance advantages in high temperature resistance. Therefore, the market price of high temperature cables is higher than that of ordinary cables. However, for some special environments with high temperature, the role of high temperature cables can not be measured by simple price. In addition to high temperature resistance, There are also many excellent performances. Firstly, of course, it has the characteristic of high temperature resistance, which is why it is named a high-temperature cable. The production materials and processes of high-temperature cables are designed to better adapt to high-temperature environments, so high-temperature cables have excellent high-temperature resistance performance. Secondly, the corrosion resistance of high-temperature cables is also excellent. During the use of high-temperature cables, due to environmental and external factors, they may come into contact with some corrosive substances, which can maintain their properties well. The chemical reaction is slow, so the use time will be longer. Moreover, high-temperature cables also have excellent electrical insulation performance. The insulation of the outer skin of high-temperature cables can ensure that there will be no leakage during use. In addition, high-temperature cables also have excellent characteristics such as flame resistance and aging resistance.

How to distinguish inferior high-temperature cables?

The method to distinguish low-quality high-temperature cables can first be based on the color of the conductor copper wire. According to national industry standards (national standards), pure copper, also known as oxygen free copper (industrial red copper, commonly known as red copper), must be used as the conductor copper wire for cables. Oxygen-free copper has a copper content of 99.9%, a relatively high purity, a bright and soft color, and copper with high oxygen content and other impurities has a dark color and low brightness. Secondly, the copper wire wiping method can also be used for identification, by wiping the copper wire with white paper. Due to the high content of impurities in unqualified copper wire and its unstable fusion with copper, it will leave black marks on the white paper after wiping. It can also be physically bent. Pure copper wire is relatively soft, has good tensile strength, and is not prone to breakage. However, those that break with a slight bend should be unqualified products.
