Usually, the resistance of the wire increases with the increase of temperature. In the whole vehicle environment, especially for traditional fuel vehicles, the engine compartment is very harsh due to the engine environment and the ambient temperature is also very high, which has a certain impact on the performance of the wire. For the promotion and use of 0.13mm2 alloy wire, it is recommended to start from the inner cabin.
From the analysis of the application range, mass ratio, electrical conductivity, mechanical strength and processing technology of 0.13mm2 alloy wires, the advantages of CuSn and CuMg alloy wires and the feasibility of replacing 0.35mm2 and 0.5mm2 pure copper wires are introduced in detail.
As the largest part of the wire harness, the promotion of 0.13mm2 alloy wire or even smaller square wire is one of the important ways.
In new energy vehicles, light weight means an increase in mileage, and an average mass saving of 5kg means an increase in mileage of 1km. The application of 0.13mm2 alloy wires is of great significance for the lightweight of the whole vehicle.
