What are the material requirements for automotive wiring harnesses?

Automotive wiring harness on the material requirements are very strict, including its electrical properties, material dispersion, temperature resistance, etc., are higher than the general wiring harness requirements, especially when it comes to the safety aspects of the requirements are more stringent.

1, the engine around the environment of high temperature, corrosive gases and liquids are also more, so the engine wiring harness wire must use high temperature, oil, vibration and friction resistant wire.

2, the automatic transmission on the wire used in the hydraulic oil, high temperature resistance, good temperature stability of the wire.

3, the wires of the harness on the luggage compartment cover have to maintain their elasticity at low temperatures, so they have to use cold elastic wires to ensure their normal operation.

4, weak signal sensor to use shielded wire.

5, ABS wiring harness assembly used to withstand high temperatures of 150-200 ℃, the outer protective insulation layer is hard, wear-resistant, but the core should be greater than 133 stranded wire.

6, power lines such as the starter alternator output line battery line used for the wire can withstand high current insulation layer heat dissipation performance, voltage reduction of special wires.
