Withstand voltage performance: the high voltage rating of conventional automobiles is 600V, and the voltage of commercial vehicles and buses can be as high as 1000V;
Current resistance performance: according to the current of high-voltage system components, it can reach 250~400A;
Temperature resistance performance: high temperature resistance grades are divided into 125C, 150°C, 200°C, and 150°C wire is usually selected for high temperature; -40°C for low temperature.
Shielding high-voltage lines can reduce the impact of EMI (electromagnetic interference) and RFIC radio interference on the vehicle system.
The entire high-voltage wiring harness circuit is shielded and connected. The shielding layer of the high-voltage wiring harness at the interface of the motor, controller, and battery is connected to the battery motor controller shell through a crimping structure such as a plug-in, and then connected to the body ground.
The shielding of high voltage lines is not necessary for the cable to conduct data, but it can reduce or avoid the radiation of high voltage lines.
