Automotive wiring harness material

The material requirements for automotive wiring harnesses are also very strict:

Including its electrical properties, material emission, temperature resistance, etc., are higher than the general wiring harness requirements, especially when it comes to safety requirements.

1. The ambient temperature around the engine is high, and there are many corrosive gases and liquids. Therefore, the wires of the engine wiring harness must use high-temperature, oil-resistant, vibration-resistant and friction-resistant wires.

2. The wire on the automatic transmission uses the wire with good resistance to hydraulic oil, high temperature and temperature stability.

3. The wires of the wiring harness on the luggage compartment cover must maintain their elasticity at low temperatures, so cold elastic wires should be selected to ensure their normal operation.

4. Shielded wires should be used for weak signal sensors.

5. The ABS wire harness assembly uses stranded wires with a high temperature resistance of 150-200 °C, a hard outer protective insulating layer and wear resistance, but the cores should be larger than 133.

6. The wires used in power lines such as starter alternator output wires and battery wires are special wires that can withstand high current and have good heat dissipation performance and reduced voltage.
