The material selection of the wire harness usually depends on multiple factors such as the application scenario, working environment, performance requirements and budget. Here are some common harness materials:
Wires and cables: Wires and cables are usually composed of conductive metals such as copper and aluminum and insulating materials. The insulating material can be PVC, PE, XLPE, Teflon, etc.
Sheaths and conduits: Sheaths and conduits are usually made of plastic materials such as PVC, PA, PP, etc. Its selection should take into account its flame retardancy, wear resistance, chemical corrosion resistance and other characteristics.
Connectors: Connectors are usually composed of metal and plastic. Its selection should take into account its contact resistance, corrosion resistance, mechanical strength and other characteristics.
Labels and signs: Labels and signs are usually made of PET, PP and other materials. Its selection should take into account its printing quality, water resistance, wear resistance and other characteristics.
Environmental factors such as temperature, humidity, chemical corrosion, and ultraviolet radiation also need to be considered when selecting a wire harness material. For automotive wiring harnesses, factors such as changes in the environment inside and outside the car, vibration, and shock also need to be considered. Therefore, manufacturers who manufacture wire harnesses need to select the most suitable materials according to customers' specific requirements and application scenarios, and conduct necessary tests and verifications to ensure the quality and reliability of wire harnesses.
