Requirements for automotive high-voltage cable specifications for hydrogen energy vehicle applications

China [CN]

Product Overview: The specifications of high-voltage cables for hydrogen energy vehicle applications need to be determined based on factors such as voltage, current, and temperature. Common specifications are as follows:

Voltage level: Passenger cars generally use a rated voltage of 600VAC/900VDC, and commercial vehicles generally use a rated voltage of 1000VAC/1500VDC.

Conductor specifications: Divided by cross-sectional area, the commonly used specifications in the new energy industry range from 1.5mm² to 120mm². For example, the wiring harness connecting the motor usually uses a larger wire diameter specification, and the other parts are selected according to specific needs.

Temperature level: Common ones are 125℃, 150℃, 180℃, 200℃, etc., and the drive motor high-voltage cable often uses 150℃ resistant materials.

Insulation properties: There are two types of insulation: thermoplastic insulation and thermosetting insulation.

Shielding type: Usually a shielded cable, the shielding layer is generally a tinned copper braided mesh with a density of not less than 85% to reduce electromagnetic interference.

Insulation core number: There are single-core and multi-core cables, which can be selected according to the specific circuit layout and electrical connection requirements of the vehicle.
