Wire processing in choosing to use wire is one of the main factors influencing the wiring harness products quality is good or bad, if you choose the strength of the conductor is not enough, in the process of wiring harness processing or use process prone to some external factors can lead to injury, fracture phenomenon in a wiring harness, especially the wiring harness products under some circumstances or bad weather use will be affected by strong winds, freezing and high temperature, the influence of such factors as especially the wire line section is small in the current overload easy overheating protection insulation are destroyed, will lead to a serious fire circuit.

When wiring harness is processed, the selection of wire should be based on the circuit requirements of customers. For low-voltage wire harness, the thickness of wire should be selected according to its heating conditions, and then the voltage loss and strength should be tested. The second is to measure the heating and voltage loss.
