The power battery of pure electric vehicles is arranged in the rear lower floor of the vehicle. The high-voltage wire harness drawn from the front end of the battery passes under the vehicle floor and is closer to the ground. It is necessary to add bellows protection to the outside of the cable to prevent the high-voltage wire harness from being damaged during driving. Stone strikes splashed on the road surface, etc.
If there is no special requirement, the high-voltage wire harness can be covered with corrugated tubes.
The closed bellows are characterized by wear resistance, flame retardancy, and heat resistance. The temperature resistance range of the bellows is -40°C~150°C, and it can reach 200°C in a short time.
Due to space requirements, corrugated tubes cannot be used for protection of wire harnesses in some locations. The solution of adding plastic wire slots outside the high-voltage wire harnesses can be considered to protect the wire harnesses. the
Panels/Wireways are typically used in areas with harsher environments. For example, the high-voltage wire harness arranged under the chassis of the vehicle needs to be protected with a guard plate/guide groove considering the possible water immersion, vehicle scratches and mud splashing.
