gui chao cable news: heat and high temperature wire and cable demand by what decision?

high temperature and high temperature wire and cable are generally determined by two requirements.
the first is the high ambient temperature of wire and cable,
the cable can transmit signals or electricity at high temperature for a long time;
another is the power transmission cable,
the main purpose is to increase the capacity of the closure.
high temperature working cable.
ordinary cables are prone to insulation aging and scorch at high temperature,
use cable to lose performance and be damaged and cannot be used.
high temperature cable can work normally and stably under high temperature,
signal or power transmission performance is not affected,
can also ensure that the cable has a long service life.
this kind of functional cable is the most common kind of high temperature cable,
the use of the most understandable.
high temperature cable,
mainly in order to ensure the reduction of cable diameter and weight under the premise of current carrying,
lightweight development. generally speaking, the higher the working temperature of the cable,
the greater the carrying capacity of the cable of the same section.
such as aircraft and automobiles, reducing weight is of great significance,
the use of high temperature cable greatly reduces the cross-section.
if the operating temperature is from 90 deg c to a temperature of 155 deg c, the current carrying capacity increases by up to 50%,
under the same load, the weight of the cable should be reduced by half,
costs are also reduced. of course, at the same time high closure,
the power consumption of most insulation materials will be increased.
