Detailed Description

Electric vehicle high voltage system has high voltage, high current loop, its safety, importance is self-evident, if the human body contact, may cause harm, so the design layout of electric vehicle high voltage wiring harness is very important. In addition, green travel is a concept advocated now. Now short-distance public transport is gradually replaced by new energy vehicles, which has higher requirements for high-voltage cables of new energy vehicles. The following is a brief introduction of high-voltage cables of new energy vehicles.




A high-voltage cable consists of a sheath, braid, strap, conductor, and insulation (from outside to inside). Of course, considering the harsh environment where high voltage cables are located, the requirements for different places are quite different.


For voltage: the main difference with the common car cable is that the frame needs to be set according to the rated voltage of 600V, and if it is applied in commercial or bus, the rated voltage can reach 1000V, which may be higher by comparison; The cables now used in cars driven by internal combustion engines are designed for a rated voltage of 60 V;


For temperature: in addition to the high temperature of the vehicle to the engine room or high temperature cabin, the rest of the electric furnace is often used to withstand the temperature of 105℃, and the high voltage cable used for new energy is usually higher than the ordinary value such as 125℃ or 150℃. Different places have different requirements for cables.


Service life: 3000h is the accepted standard for cable, this value is commonly used in long-term aging tests. In the application of high pressure field in the application of high pressure field will have special requirements, may exceed 3000 h, in the specified temperature accumulated running time even up to 12000 h; Safety label: High voltage cable will bring some risks to users, high voltage cable should be visually distinguished from ordinary cable, and also marked with safety warning label.
