Special concepts for the design of automotive high-voltage wiring harnesses

China [CN]

The cable of automotive high-voltage wiring 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 there is alternating current in the conductor will produce a "skin effect", and the higher the frequency, the more obvious the effect. There is also a high voltage harness platform for new energy vehicles, taking into account the difficulty of wiring in the car, coupled with the strength, toughness and safety of the cable, multi-core wire is a more ideal choice.

The current will generate a magnetic field, so the general high-voltage wiring harness needs to be set up a shielding layer, which can not only reduce electromagnetic radiation, but also shield external influences and prevent interference from external magnetic fields.

Of course, some people may think that the thicker the harness, the better, in fact, not sure that the experimental results prove that it is generally necessary to choose the right product according to the current and voltage, due to the harsh conditions of high voltage harness use, the standard is also more strict, high voltage harness safety and durability is also an important factor affecting the choice.
