Why should the cable be maintained
May 10, 2018

The length of life of the cable depends on the quality of the cable and the environment in which the cable is installed. The cable is mainly insulated by a layer of external insulation. Over time, it is corroded by corrosive gases. The insulation performance gradually decreases, and it slowly ages and hardens, and becomes brittle or falls off. Loss of insulation performance of the cable is very dangerous. If the two cables collide with each other or if the fire wire touches something that touches the earth, power running will occur, causing the temperature of the local wire to rise, creating sparks and causing fire.
