“ Cables work under high temperature conditions. General cables are prone to insulation aging and burning at high temperatures, resulting in the loss of performance, damage, and inability to use the cables. At rated temperature, high-temperature cables can operate normally and stably without affecting signal or power transmission performance, while also ensuring the service life of the cable. ”

Cables work under high temperature conditions. General cables are prone to insulation aging and burning at high temperatures, resulting in the loss of performance, damage, and inability to use the cables. At rated temperature, high-temperature cables can operate normally and stably without affecting signal or power transmission performance, while also ensuring the service life of the cable. This functional cable is the most common type of high-temperature cable, and its usage characteristics are also the easiest to understand. The main purpose of increasing the load of high-temperature cables is to reduce the outer diameter and weight of the cables under the current carrying conditions mentioned in the previous question, and to develop towards lightweight. In general, the higher the working temperature of a cable, the greater its current carrying capacity on the same cross-section. In situations such as airplanes and cars, weight reduction is of great significance, and the use of high-temperature cables can greatly reduce the cross-section. When the working temperature is increased from 90 ℃ to 155 ℃, the current carrying capacity increases by 50%. Under the same current carrying conditions, the weight of the cable is reduced by half and the cost is reduced. At the same time as the interception flow is large, the loss of most insulation materials will also increase.
