High-voltage harnesses should use permanent orange materials for visual recognition. Cables that are wired separately without auxiliary covers should use a single orange color, and the cover can be a bellows, tape, or heat shrink tubing, etc. Copper is currently the most commonly used cable material for wires, with good electrical conductivity and high thermal stability. In addition, due to the high requirements for weight and space in new energy vehicles, some new types of high-conductivity materials such as aluminum alloy wires have also begun to be used in wire manufacturing. During the production process, the selection of cables depends on the different power systems carried by different models and tonnage of vehicles, and cables of corresponding diameters are matched according to the actual power to achieve a reasonable and compliant cable selection.
Cable selection also requires that the insulating material of the cable should be consistent with the vehicle’s working environment and able to withstand physical and environmental factors such as bending, overheating, overcooling, bending, liquid intrusion, wear, short circuits, and compression. Each link in the production process is also extremely important after the design is completed.
