Automotive wiring harnesses also have very strict material requirements:
Including its electrical properties, material dispersion, temperature resistance, etc., are higher than the general wiring harness requirements, especially when it comes to safety.
1. The ambient temperature around the engine is high, and there are more corrosive gases and liquids, so the wires of the engine harness must use high-temperature, oil-resistant, vibration-resistant and friction-resistant wires.
2. The wire on the automatic transmission is made of wire with hydraulic oil resistance, high temperature resistance and good temperature stability.
3. The wire of the harness on the luggage compartment cover should maintain its elasticity at low temperature, so the cold elastic wire should be selected to ensure its normal operation.
4. Weak signal sensors should use shielded wires.
5. ABS harness assembly uses 150-200 °C high temperature resistance, hard outer protection insulation layer, wear resistance, but the wire core is greater than 133 stranded wires.
6. The power line such as the starter alternator output line and the wire used in the battery line are special wires that can withstand the heat dissipation performance of the high-current insulation layer and reduce the voltage.
