Specification difference of automobile high voltage cable

Automobile high-voltage cable | about the thickness of high-voltage harness: in fact, the use principle of household wire is the same as that in other electrical fields, such as new energy vehicles. For example, put two kinds of high-voltage lines of two vehicles together for comparison. The conclusion is "the high voltage harness of car a (thin wire) is thin and of poor quality".

Of course, these are two kinds of high-voltage lines, which have different functions and cannot be compared directly. There are many kinds of high-voltage harnesses used in cars, such as 3mm2-50mm2 or even 70mm2. Taking pure electric vehicles as an example, under the same high voltage close to 400V, the high voltage line used by 85KW motor must be different from that used by 6.6kw charger - "thick" is the difference in the cross-sectional area of copper wire, which is also obvious. Therefore, the high-voltage harness required on the vehicle is assembled in different parts according to the power demand.

Spare parts connected to the vehicle by high-voltage harness, including drive motor, air conditioning system, on-board battery, etc. These applicable materials are also commonly used according to the matching requirements of the equipment, such as 125 ℃ XLPE and 180 ℃ silica gel, which have high and low temperature resistance and tear resistance. The cable material is thermosetting material, and the wires and cables are soft and smooth. Cables of different specifications and models are made of shielded or unshielded materials.
