How to Select Wire Harness Materials

The quality of wire harness materials directly affects the quality of the wire harness, and the selection of wire harness materials is related to the quality and service life of the wire harness. So when choosing harness products, users should not be greedy for cheap, as cheap harness products may be inferior harness materials. Below, the editor will introduce how to choose wire harness materials.

The wiring harness is generally composed of wires, insulation sheaths, wiring terminals, and wrapping materials. As long as you understand these materials, you can easily distinguish the quality of the wiring harness.

1. Material of terminal blocks

The copper used for terminal materials (copper parts) is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), with brass accounting for a larger proportion. In addition, different coatings can be selected according to different needs.

2. Insulating sheath

The commonly used materials for sheath materials (plastic parts) include PA6, PA66, ABS, PBT, pp, etc. Flame retardant materials can be added to plastics according to actual conditions to achieve flame retardant purposes, such as adding glass fibers.

3. Wire harness

Select the corresponding wire material according to the different usage environment.

4. Binding materials

Wire harness wrapping plays a role in wear resistance, flame retardancy, corrosion prevention, interference prevention, noise reduction, and beautification of appearance. Generally, the selection of wrapping materials is based on the working environment and space size. In the selection of wrapping materials, there are usually adhesive tapes, corrugated pipes, PVC pipes, etc.
