How to choose the material of the wire harness

The quality of the Wire Harness material directly affects the quality of the wire harness, and the selection of the wire harness material is related to the quality and service life of the wire harness. Remind everyone, in the selection of wire harness products, you must not be greedy for cheap, cheap wire harness products may use inferior wire harness materials. How to distinguish the quality of the wire harness? Once you understand the material of the wire harness, you will understand. The following is the information on the wire harness selection.

The wiring harness is generally composed of wires, insulating sheaths, terminals and binding materials. Once you know these materials, you can easily tell the good from the bad.

1. Material selection of terminal blocks

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

2. Selection of insulating sheath

The commonly used materials for the sheath material (plastic parts) mainly include PA6, PA66, ABS, PBT, pp, etc. Flame retardant or reinforcing materials can be added to the plastic according to the actual situation to achieve the purpose of reinforcement or flame retardant, such as adding glass fiber reinforcement, etc.

3. Selection of wiring harness wires

According to the different use environment, select the corresponding wire material.

4. Selection of dressing materials

Wire harness wrapping plays the role of wear resistance, flame retardancy, corrosion prevention, interference prevention, noise reduction, and beautification of appearance. Generally, the wrapping material is selected according to the working environment and space size. In the selection of dressing materials, there are usually tapes, corrugated pipes, PVC pipes, etc.
