Heat resistant and high temperature cable is usually made of two kinds of demand of the decision. A wire and cable is using the environment temperature requirements, cable long-term under high temperature can normal signal transmission, or electric power; Another is the electric power transmission, main river closure ability is to increase for the main purpose. power cable

Heat resistant and high temperature electric wire and cable are generally made of two kinds of demand of the decision. The first kind is cable environment temperature is higher, cable in long-term under high temperature can normal signal transmission, or electric power; Another is the electric power transmission cable, main river closure ability is to increase for the main purpose.

Under the environment of high temperature of cable. Ordinary cable in high temperature easy generation insulation aging and coke burning phenomenon, using cable lose performance, destroyed and can not be used. High temperature cable in under the high temperature stability can be rated normal work, signal or power transmission performance not affected, can guarantee cable has long service life. This kind of function cable is the most common of high temperature cable at most a, use the most easy to understand the characteristics.

Add in high temperature type cable, main is to ensure that the current-carrying before problem to reduce weight and cable diameter, to the development of lightweight. Generally speaking, the working temperature of cable, the higher the same section of the carrying capacity of the cable through. As aircraft and cars and so on, the meaning of the weight is quite large, using high temperature cable greatly reduces the section. Working temperature 90 ℃ from went up to 155 ℃, current-carrying capacity is up by 50%, and the same load flow, cable weight to reduce half, Aluminum sheet costs are reduced. Of course the high river closure and at the same time, most of the insulation material electric power also can increase somewhat.
