Abstract: A transition joint for sealing an electrical coaxial cable having an oil-impregnated or fluid filled layer. The transition joint has two primary elements, an electrically insulative elastomeric tube and a heat recoverable sleeve. In connecting a paper-insulated, lead jacketed cable to an extruded dielectric cable, the elastomeric tube is placed in tight conformity around the paper layer, slightly overlapping the lead jacket and the central conductor, and further partially overlapping a connector joining the conductors of the cables. The heat recoverable sleeve is then contracted over the elastomeric tube, overlapping the lead jacket and the central conductor, and partially overlapping the connector. The heat recoverable sleeve mechanically restricts the elastomeric tube, preventing the elastomeric tube from swelling which, in turn, precludes absorption of the oil, which would otherwise cause the elastomer to degrade.
