The Importance of Wire Selection in Automobile Wire Harness Processing

Car lines of different specifications have different data processing, and there are certain requirements for the use of electrical functions, temperature resistance, and wear resistance. Ensuring the stability of the car is the first requirement for car manufacturers, no matter whether the engine is still the direction control, brake and other wiring harnesses, it is necessary to strictly buy the wires in accordance with the specifications, otherwise it will present severe safety hazards.

Autodesk harness is an old car line brand and has many years of cooperation experience among car companies. It summarizes the following requirements for line selection:

1. Car starters, generators, batteries and other parts require that the wires can follow large currents, and the insulation layer can also quickly dissipate heat.

2. The ambient temperature around the engine gearbox is high, and there are more corrosive gases and liquids. Therefore, the wires of the engine wiring harness must be resistant to high temperature, oil, oscillation, and conflict.

3. The wiring harness used in the trunk should be bent frequently. Generally, it should be protected by some sheaths. Cold elastic wires should be selected for internal wires to ensure their normal operation.

4. Weak signal sensors should use shielded wires, such as knock sensors, crankshaft azimuth sensors, ABS wheel speed sensors, etc.

5. The ABS harness assembly is resistant to high temperature of 150-200 ℃, the outer protective insulation layer is hard and wear-resistant, but the core is larger than 133 stranded wires.
