For the thickness of vehicle high-voltage cables, the principle of use of household cables is the same as that of other electric fields. For example, by comparing two types of high-voltage wires (divided into thick and thin wires) from two vehicles, it can be concluded that the quality of "thin wire" high-voltage wire harnesses is lower than that of "thick wire" high-voltage wire harnesses. However, the two methods of comparison may have certain differences due to their different applications and functions.
There are many specifications and models of vehicle high-voltage lines, such as 3mm ²- 70mm ²。 Taking an electric vehicle as an example, at a high voltage of nearly 400V, there is a significant difference between the high-voltage wire used for an 85KW motor and the high-voltage wire used for a 6.6KW charger - the "thickness", that is, the cross-sectional area of the copper wire, which is also significant. Therefore, the vehicle high-voltage wiring harness is assembled on different components based on power requirements.
Application: High voltage harnesses are connected to components on vehicles, including drive motors, air conditioning systems, on-board batteries, etc. According to the matching requirements of the equipment, these suitable materials are also commonly used materials, such as 125 ℃ XLPE and 180 ℃ silicone, 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. Shielded or unshielded materials are used for cables of different specifications and models.
