Importance of wire selection in automobile wire harness processing

Car lines with different specifications have different data processing. There are certain requirements for the use of electrical performance, temperature resistance, wear resistance, etc. to ensure the stability of the car is the first indication of car manufacturers. Whether it is the engine or the direction control, brake and other wiring harness, we must strictly purchase the wire in accordance with the specifications, otherwise there will be serious security risks.

As an old brand of car line, Haozhi wire harness has many years of cooperation experience with automobile enterprises. It summarizes the following requirements for line selection:

1. The starter, generator, battery and other parts of the car require that the conductor can follow the large current, and the insulation layer can also quickly dissipate heat.

2. The ambient temperature of the engine gearbox is high, and there are many corrosive gases and liquids. Therefore, the wires of the engine harness must be high temperature resistant, oil resistant, vibration resistant and friction resistant.

3. The harness used in the trunk should be bent frequently. Generally, it should be maintained with some sheaths. The internal wires should be cold elastic wires to ensure their normal operation.

4. The weak signal sensor should use shielded wires, such as knock sensor, crankshaft orientation sensor, ABS wheel speed sensor, etc.

5. The twisted wires used in ABS wiring harness assembly are resistant to high temperature of 150-200 ℃, hard external maintenance insulation layer, wear-resistant, but with more than 133 cores.
