As an automotive interior device to operate effectively, automotive high-voltage cables play an important role in it. The technology of key components such as batteries, motors, and electronic controls is inseparable from high-voltage wiring harnesses.


The appearance of high-voltage cable sheath is generally cross-linked polyethylene insulation, XLPE, PVC, etc., but the structure of high-voltage cable is composed of core, inner insulation layer, semiconductor layer, steel armor, filler, outer insulation layer, etc.; conductor is copper or plated Tin copper, but in conventional cables, copper is mostly used as the conductor. Cables with different uses use different materials, but the cores are copper or aluminum. The specific use of copper, aluminum or tinned copper is related to the price of the market materials and can only be used in special cables.


However, how many layers of high-voltage cables do they play?

The high-voltage electricity is sealed to three layers, the innermost layer of the first layer is an insulating layer, and the next layer is a conductive layer, among which there are shielded or unshielded cables. The shielded cable has an improved electric field. As a measure of distribution, a conductor wrapped with a conductor outside the conductor is called a shielded wire. The conductor wrapped with a conductor outside the conductor is called a shielded wire, and the wrapped conductor is called a shielding layer, which is generally a braided copper mesh or copper moor (aluminum). Of course, the inside of the cable is a conductor, which conducts electricity as a whole product. The overall cable forms an insulating layer that truly protects the entire cable, and is generally divided into three layers for the correct function without damaging the cable.
