What documents do you need to make a high-voltage cable head?

High-voltage cable head requires cable accessories installation certificate.

In particular, the metal shell of the connector is electrically continuous with the metal shield and insulation shield of the connected cable. In order to reduce the induced electromotive force of metal sheath, high-voltage lines need insulated joints to realize cross transposition connection to eliminate the circulating current caused by induced electromotive force.

Insulating joint A joint that disconnects the metal sheath, metal shield and insulation shield of a cable. According to its function in the line, cable joints can have branch joints and transition joints in addition to insulation joints and straight-through joints.
