The high-voltage wire consists of a secondary sheath (also called an outer insulation layer), aluminum foil, a shielding braid, an inner insulation layer and a core wire (conductor).
Industry standards can refer to "QC-T1037 Automotive Industry Standard for High Voltage Cables for Road Vehicles" and "High Voltage Cables for New Energy Vehicles TCAS 356-2019".
Some high-voltage wires have a layer of tape between the shielding layer and the secondary sheath. The function of the tape is to facilitate the stripping of the insulating layer during the production of crimp terminals. The material similar to non-woven fabrics is wrapped around the wire to play a certain role. isolation effect.
The main structural size parameters of high-voltage wires are also around these layers of elements, including the outer diameter of the secondary sheath, the diameter of the inner insulating layer, the diameter of the conductor, the diameter of a single copper wire, and the number of copper wires.
