What are the similarities and differences between EV high voltage cables and EV low voltage cables?

Cables play a great role in the entire electric vehicle, and are known as the "nerve of electric vehicles" and are the source of power. The internal wiring of new energy electric vehicles has both high-voltage cables and low-voltage cables. What are the similarities and differences between the two cables?

First of all, the voltage is different. High-voltage cables are generally above 60V, and some wiring inside electric vehicles can even reach 1500V. Low-voltage cables are generally below 60V, generally used for system wiring such as air conditioners, sensors, etc., usually 48V. Although the voltage seems to be very low, in the event of danger, it is enough to cause serious disasters to the human body.

Color requirements, we all know that high voltage will harm the human body, so the relevant standards stipulate that the outer sheath of high-voltage cables needs to be marked with orange to play a warning role. Low-voltage cables generally have no color requirements.

Due to different materials, the internal environment of the car is harsh, and there are higher requirements for the high-voltage cables that drive the car. For the selection of insulating materials, a higher level is generally required. The thickness of the insulating layer is strengthened to increase electrical performance and reduce electromagnetic interference. Protect the body and the human body. Relatively speaking, low-voltage cables can be made of cheaper materials. As long as the production process and raw materials are no problem, the basic problem is not big.

Performance requirements, high-voltage cables need good flexibility to face the narrow space environment inside the car. Under normal circumstances, 3000 hours of aging resistance test is required, and the product has high requirements for high temperature resistance. Since they are both used in the car, both need to have good acid and alkali resistance, oil resistance and other properties.

OMG manufacturers always implement the concept of "only for safety", focus on the latest technological trends in the cable industry, adhere to the orientation of technological innovation, constantly seize development opportunities, and take the belief of providing safe and high-quality cables to win customers' praise with professional products.
