5. 0.13mm2 wire conductive performance

Based on the conductivity of the nude copper wire, the copper content of the naked copper wire is about 99.9%, the conductivity is 100%, and at a normal temperature of 20 ° C, the conductivity is ≥58.58MΩ/mm2; Among them, the MG content is about 0.14%~ 0.26%, the conductivity of the CUMG alloy wire is ≥44MΩ/mm2, and the conductivity is about 75%. In the copper tin alloy wire, the content of SN is about 0.25%to 0.35%, the conductivity of the CUSN alloy wire is ≥42MΩ/mm2, and the conductivity is about 72%. Take the nude copper wire of 0.35mm2 as an example. Their wire resistance value is about 54.4Ω/km. More than 5m, the maximum is about from the instrument of the luggage compartment to the BCM or gateway, so even if it is a alloy wire of 0.13mm2, its wire resistance is also very small and will not affect the signal.

Usually the resistance of the wire increases with the increase in temperature. In the vehicle environment, especially for traditional fuel models, the engine compartment has a very bad engine environment and a very high environmental temperature, which has a certain impact on the performance of the wire. For the promotion and use of 0.13mm2 alloy wires, it is recommended to start from the inner cabin.

Six, conclusions

This article analyzes the application range, quality proportion, conductivity, mechanical strength and processing technology of 0.13mm2 alloy wires, and introduces the advantages of CUSN and CUMG alloy wires in detail, replacing the feasibility of 0.35mm2 and 0.5mm2.

As part of the most proportion of wire beams, it is one of the important ways to promote the 0.13mm2 alloy wire or even lower small flat -icon.

In new energy models, lightweight means the increase in mileage. The average quality savings per 5kg means the increase in 1km driving mileage. Applying a 0.13mm2 alloy wire is of great significance for the lightweight of the vehicle.

The connection point of the wire beam refers to the hinged point of 2 or more (including 2) wires in the wiring beam. As shown in Figure 1. No. 1 series contact line is from Line 1,

The 1B line and the 1C line are composed of 3 lines. The interior of the three line beams is connected to each other. The hinged connection point inside the 3 line online beam is the contact.
