What is most needed now is the high temperature cable with heat resistance and high temperature resistance, because the wire

 and cable operates in a high temperature environment for a long time, so the heat resistance of the wire and cable must 

be ensured. According to the characteristics of high temperature resistance of the wire and cable, two points are introduced in detail.

1. For load-type high-temperature wires and cables, it is important to reduce the diameter of the cables and components to ensure 

the current carrying capacity and to carry out light weight. It is especially important to note that the higher the working temperature

 of the cable, the higher the carrying capacity of the same cross-section of the cable. For aircraft, automobiles and other venues, 

the meaning of heavy weight is commensurate, and the application of high-temperature cables greatly reduces the cross-section.

 When the task temperature rises from 90°C to 155°C, the ampacity can be increased by 50%. Under the same load capacity, 

the cable structure will be increased by half, and the cost will be reduced. Naturally, the power consumption of most insulating 

materials also increases with high closure.

2. Cables for working in high temperature environment. Ordinary wires and cables are easy to be insulated and 

aged at high temperatures. If they are burned, the cables will lose their performance due to damage and cannot 

be used. High temperature wire and cable can work normally and stably under ultra-high temperature without affecting

 signal or power transmission performance, and can also ensure a long service life of the cable. This kind of functional 

wire and cable is more common than high temperature wire and cable, and the use characteristics are also well understood.
