Common faults of high voltage cable-2

Common faults of high-voltage cables are breakdown near the root of the plug
The breakdown of the root of the high-voltage cable close to the plug: Generally, both ends of the high-voltage cable are corroded by transformer oil or vanadium for a long time, and the rubber of the high-voltage insulation layer is corroded, which reduces the insulation resistance and causes the breakdown. In addition, the two ends of the cable are often accompanied by pipe balls. Moving up and down, left and right back and forth, or the twisting and bending radius is too small, causing tiny cracks. When there is an air gap at the root of the cable plug, the air part is subjected to a higher potential gradient, which is easy to move away first, causing its insulation strength to be damaged. A longer period will inevitably lead to breakdown.
