How to avoid cable failure? How to avoid cable failure? Cable failure detection Now it is often possible to detect cable failure, which is very dangerous, so how to avoid it? First of all, we should analyze the cause of the failure. The cable fault tester analyzes chemical corrosion, the buried power cable path may pass through the acid-base operation area, and the underground power cable may fail due to corrosion. The insulation of the cable surface is aging. As the cable is used for a long time, it is normal for the insulation skin to age. In addition, the local heat in the ground is large, which may damage the insulation surface.
Overvoltage, rain, lightning strikes and other high voltages may also cause power cables to fail. The mechanical damage when installing the cable may mainly be caused by the installation personnel being careless during operation and installation, the cable fault detection or the careless mechanical damage of the cable caused by other operations. These situations will cause the cable to fail. Once the cable fault tester is found to be faulty, it should be repaired immediately.
