What principles should be followed in the selection of wire harness materials?

The good or bad of the wire harness material of the wire harness processing plant directly affects the quality of the wire harness, the choice of the wire harness material, which is related to the quality and service life of the wire harness. In the choice of wiring harness products, must not be greedy for cheap, cheap wiring harness products using perhaps poor quality wiring harness materials. How to distinguish between good and bad harness quality? Wiring harnesses are generally composed of wires, insulating sheaths, terminals, and wrapping materials. As long as you understand these materials, you can easily distinguish between good and bad harnesses.

First, the material selection of the terminal: terminal material (copper parts) with copper is mainly brass and bronze (brass hardness than the hardness of bronze slightly lower), of which brass accounted for a larger proportion. In addition, different plating can be selected according to different needs. Second, the choice of insulation sheath: sheath material (plastic parts) commonly used materials are mainly PA6, PA66, ABS, PBT, PP and so on. According to the actual situation in the plastic to add flame retardant or enhancement materials to achieve the purpose of enhancing or flame retardant, such as adding glass fiber enhancement. Third, the choice of wire harness wire:According to the use of different environments, select the appropriate wire material. Fourth, the choice of wrapping materials: harness wrapping to play a wear-resistant, flame retardant, corrosion-resistant, prevent interference, reduce noise, beautify the appearance of the role, generally according to the working environment and the size of the space to choose the wrapping material. In the choice of wrapping materials are usually tape, bellows, PVC pipe, etc..
