Abstract
A joint in a high-voltage cable with electrical conductors surrounded by solid insulation, the conductor insulation at the joint having a coating the resistivity of which is lower than that of the conductor insulation. The space around the jointing sleeve of each joint and between the cut insulation of the conductors is filled with a weakly conducting material to a diameter which is approximately equal to the diameter of the conductor insulation, the coating being in electrical connection with the conducting material surrounding the jointing sleeve.
