Automotive wire harness has very strict requirements on materials:
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 resistant, oil-resistant, vibration-resistant, and friction-resistant wires.
2. The wires on the automatic transmission use wires that are resistant to hydraulic oil, high temperature, and have good temperature stability.
3. The wires of the wiring harness on the luggage compartment cover should maintain their elasticity at low temperature, so cold elastic wires should be selected for normal operation.
4. Weak signal sensors should use shielded wires.
5. The ABS wire harness assembly uses high temperature resistance of 150-200°C, hard outer protective insulation layer, wear resistance, and the wire core is combined into a stranded wire.
6. The wires used for power lines such as starter alternator output wires and battery wires are special wires that can withstand large currents, have good heat dissipation performance of the insulation layer, and reduce voltage.
