It is found that more new energy vehicles are running on the road today, and the connecting equipment high-voltage cables used in vehicles have different specifications, such as shielded and unshielded high-voltage cables. The application equipment specifications and models used are different, but the purpose is to connect the vehicle high-voltage equipment.

High voltage cables for new energy electric vehicles Voltage. At present, the cable rating standard used in conventional vehicles driven by internal combustion engines will lead to high power consumption and heating of components. Therefore, high-voltage cables must be designed to withstand higher temperature range and other requirements and standards.

Different from the 12V voltage of traditional vehicles, the high-voltage cables need to consider the prevention of overheating or burning, shielding performance, waterproof and dust-proof, and electromagnetic compatibility with the vehicle electrical system. In actual use, the magnetic interference generated by the high-voltage cables will affect the integrity and accuracy of data transmission in the vehicle signal line, and seriously affect the safety of the vehicle. Therefore, the high-voltage cables need to use shielded wire and other methods to reduce magnetic interference, Cables related to battery pack voltage acquisition and temperature acquisition have high requirements for crimping process, so hydraulic equipment is needed to replace the traditional process. In order to reduce fuel consumption, aluminum is used to replace copper widely used at present to process high-voltage cables, which is also a trend of technological development.
