In the traditional models of Front Seal, most of the signal lines use 0.35mm2 and 0.5mm2 wires, and their mass is 4.5kg/km and 6.5kg/km respectively, while the mass of 0.13mm2 is only 2.0kg/km (0.13mm2 pure copper wire). Similar to the quality of the alloy wire), the application of 0.13mm2 can reach 55%~69% for the quality of the signal wire. The signal wires of the low-voltage wiring harness of the vehicle can be roughly divided into Lin, CAN, Ethernet, LVDS, etc. Among them, Lin and CAN wires are mostly used. Ethernet, LVDS, etc. are semi-finished wires with relatively high prices. Small. Taking a brand of new energy pure electric SUV as an example, the whole vehicle Lin network uses all 0.35mm2 wires, the dosage is about 80m, the copper weight of the wires is about 0.36kg, and the CAN network uses all 0.35mm2 wires, and the dosage is about 120m , the copper weight of the wire is roughly 0.54kg. If all the above wires are optimized to 0.13mm2 wire, the copper weight of the wire harness will be reduced by 0.5kg.
