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.
