What is special about the design of high-voltage wiring harnesses for vehicles?
发布日期:2026-03-21 11:48:53

The cable of the automotive high-voltage harness is composed of a large number of copper wires, and the cable conductor structure is integrated with a large number of copper wires, which can effectively increase the conductivity. Because the presence of alternating current in a conductor produces a “skin effect”, and the higher the frequency, the more pronounced this effect becomes. Another advantage is that the voltage platform of the high-voltage wiring harness for new energy vehicles is relatively high. Considering the difficulty of wiring inside the vehicle, as well as the strength, toughness, and safety of the cables, multi-core wires are an ideal choice.
The passage of current will generate a magnetic field, so generally high-voltage wire harnesses need to be equipped with shielding layers, which can not only reduce electromagnetic radiation, but also shield external influences and prevent interference from external magnetic fields.
Some people may think that thicker wiring harnesses are better, but this is not the case. Generally, it is necessary to choose the appropriate product based on current and voltage. Due to the strict usage conditions and standards for high-voltage wiring harnesses, safety and durability are also important factors affecting the selection.
Paige Rui high-voltage wiring harness has shielded and unshielded structures. Based on mature technical concepts and strict technical specifications, our high-voltage wiring harness can operate in ambient temperatures up to 1000V. Can meet users’ different requirements for cable structure, outer diameter, and shielding rate. The high-voltage wire harness is soft, with a small bending radius and a flame retardant rating of UL94V-0/VW-1. It meets RoHS/REACH standards and has excellent physical and mechanical properties, as well as overload resistance. It can provide efficient and durable guarantees for the safe and efficient transmission of high-voltage electrical energy in electric vehicles.
