Common breakdown of high voltage cable connector
Breakdown of high-voltage cable connector (or socket): breakdown of high-voltage cable connector or socket, mostly due to the insulation filler between the connector and socket for a long time and getting damp; the filler contains impurities, or the connector and socket are not treated clean; there are bubbles between the high-voltage connector and socket, causing high-voltage breakdown. Because there are impurities in the liquid, when the voltage is applied, there is leakage current inside. The heat generated by this current makes the filling material melt and flow out, and the air enters the gap between the connector and socket, causing the connector to discharge along the surface.
