The selection of high-voltage cable materials in new energy vehicles is crucial because they directly affect the performance and safety of the vehicle. High-voltage cables in vehicles need to have properties such as high and low temperature resistance, oil and water resistance, flame retardancy, tear resistance, insulation, and UV aging resistance.
XLPE material has become a common insulating material for high-voltage cables due to its heat resistance and mechanical properties. At the same time, the design of high-voltage cables in vehicles also needs to consider factors such as wiring space, high current and high voltage, high and low temperature environment, and harsh conditions of the vehicle driving environment.
The selection and design of high-voltage cables in new energy vehicles must meet relevant international and domestic standards, such as ISO 6722, QC/T 1073, CQC1122, etc., to ensure the performance and safety of the cables. The insulation layer material of the cable needs to have good heat resistance and mechanical strength to adapt to the high temperature and mechanical pressure inside the vehicle. In addition, the high-voltage cable should also have high flexibility to adapt to the tight bending radius and continuous vibration environment inside the vehicle.
