Abstract: A re-enterable cable jointing connector for electrical power distribution network cables and the method of using the connector to isolate cables physically and chemically one from another, the connector having at least two current carrying elements, each having at least three connection portions to which the individual cable cores may be attached, and having an electrically insulating body. The insulating body substantially surrounds the current carrying elements and extends at least up to the connection portions, thereby electrically insulating the current carrying elements from one another and interfacially isolating the cables from one another. Cables which are size, configuration or material incompatible may be jointed. Power cables may be optionally provided with in-line joints, branch joints or service connections by means of this compact connector.
