Heat-resistant and high-temperature electronic wires. It is 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 electronic line, which is mainly for increasing the interception capacity.
Electronic wire harness working in high temperature environment. Ordinary electronic wires are prone to insulation aging and scorching at high temperatures, and the use of cables loses performance and is damaged and cannot be used. The high temperature 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. This type of functional cable is the most common type of high-temperature electronic wire, and its use characteristics are also the easiest to understand.
Load-increasing type high temperature electronic wire harness. The main purpose is to reduce the outer diameter and weight of the cable under the prerequisite of current-carrying, and develop towards lighter weight. Generally speaking, the higher the operating temperature of the electronic wire, the greater the current carrying capacity of the cable of the same cross-section. For occasions like airplanes and automobiles, weight reduction is of great significance, and the use of high temperature 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, while the current is high, the power loss of most insulating materials will increase.
