Green travel is now advocated a concept, and now the short-distance public transport mode of travel is gradually replaced by new energy vehicles, then the high voltage cable requirements for new energy vehicles are higher, the following is a brief introduction to the high voltage cable requirements for new energy vehicles.
1, voltage: The main difference between the common automotive cable line is that the frame needs to be designed according to the rated voltage of 600 V, and if it is applied in commercial vehicles and buses, the rated voltage can reach 1000 V. The voltage limit may be higher in comparison. The cables used today in cars driven by internal combustion engines are designed with a rated voltage of 60 V.
2, temperature: Now in addition to the high temperature of the vehicle to the cabin or high temperature cabin, the rest of the cable is often used to withstand the temperature of 105 ° C, and the new energy used is high
The pressure cable is usually higher than the ordinary value such as 125℃ or 150℃. Different places have different requirements for cables.
3. Working life:
The recognized cable standard is 3000h, which is commonly used in long-term aging tests. In the application of high pressure field will have special requirements, it is possible to exceed 3000 h, and the cumulative operating time at the specified temperature can even reach 12000 h.
4. Safety sign:
High voltage will bring a certain risk to the user, the high voltage cable should be visually distinguished from the ordinary cable, but also printed with safety warning signs.
Through the above content can be distinguished from the surface of the logo, which can have a security guarantee for the user.
