What is a high-temperature resistant cable?

High-temperature resistant cables are generally determined by two requirements. The first is the high ambient temperature of the wire and cable, and the cable can normally transmit signals or electric energy under high temperature for a long time; the other is the power transmission cable, which is mainly for increasing the interception capacity.

Cable working in high-temperature environment. Ordinary cables are prone to insulation aging and scorching at high temperatures, and the use of cables loses performance, is damaged, and cannot be used. The high-temperature resistant cable can work normally and stably under the rated high temperature, the signal or power transmission performance is not affected, and the cable has a long service life. Like silicone cables, rubber cables.

The load-increasing high-temperature resistant cable is mainly to ensure that the outer diameter and weight of the cable are reduced under the precondition of current-carrying, and it is developed to be lighter. Generally speaking, the higher the working temperature of the cable, the greater the current carrying capacity of the cable of the same cross-section. For example, in occasions such as airplanes and automobiles, weight reduction is of great significance, and the use of high-temperature resistant cables greatly reduces the cross-section. When the operating temperature rises from 90°C to 155°C, the current-carrying capacity increases by 50%. At the same current-carrying capacity, the weight of the cable is reduced by half and the cost is also reduced. Of course, at the same time as high current interception, the power loss of most insulating materials will also increase.
