Harness processing plant for the type of wire selection principles which

1, according to the ambient temperature to choose, for example: the engine ambient temperature is high, corrosive gases and liquids are also many. Therefore, we must use high temperature, oil, vibration, friction-resistant wire; luggage compartment cover wire to maintain its elasticity at low temperatures, so use cold elastic wire to ensure its normal work; automatic transmission wire must be resistant High temperature, hydraulic oil resistance, its temperature stability is better; because the car exhaust pipe temperature is high, in the layout of the wiring harness should try to stay away from the exhaust pipe, if you can not avoid the need to use more than 200 ℃ wire, The wire used for brake shoe harness requires abrasion, impact resistance (sediment) and high and low temperature (temperature cycling) shocks.

2, the main sensor and strong interference near the sensor and weak signal sensor to use shielded wire to prevent electromagnetic interference.

3, to determine the wire standard, the different standard wire conductor structure, nominal cross-section, insulation material and thickness, performance requirements and the maximum outside diameter are some differences, at present China has begun to use the following organizations to develop automotive wire standards: ISO, SAE, DIN, JIS, VW, PSA, etc., commonly used in the type of wire bus standard (AVSS, etc.), GB (QVR), German standard (FLRY), and other major series.
