Recently, I received a customer’s inquiry about the after-sales problem of high-voltage cable, saying that it was broken when the customer used it, so it was convenient for the terminal to coordinate.
It is found that the unskilled welding technology makes the metal port of the metal mesh and cable head weld for a long time, resulting in the local temperature of the insulation layer too high and aging, and the insulation strength is reduced. When the temperature is too high, the filler will melt and flow out, and air gap will appear. High voltage cable is easy to break.
The customer decided to buy a supplement and asked a special technician to operate.
