  • Cable blocking
    Patent number: 5281763
    Abstract: An electrical cable in-line or branch joint has hydrophobic material located around the connections of the conductors so as to act as a water block. The hydrophobic material is physically prevented from being forced away from the connections into the cables, for example by pressure of water within the cable, by a fibrous material located in and around the crutch regions where the conductors emerge from the cable joints.

    Abstract: Connection between a high voltage electric cable and the bushing of a transformer is achieved by firstly terminating the cable using heat shrinkable insulation tubing and stress control material, and secondly push-fitting the terminated cable into an insulating elbow. Mechanical retention of the cable in the elbow also provides electrical connection therebetween, for subsequent connection on to the bushing.
