A sealed cabled assembly includes a cable and a cable moisture seal assembly. The cable includes a cable subcore, a metal shield layer surrounding the cable subcore, and a jacket surrounding the metal shield layer. The cable subcore includes an electrical conductor surrounded by an electrical insulation layer. The cable moisture seal assembly includes a sealant, a electrically conductive jumper member, and an outer sleeve. The cable includes a sealing region section extending from a first axial end to a second axial end, and in which a section of the jacket and a section of the metal shield layer are removed to expose a section of the cable subcore. The insulation layer and the conductor extend through the sealing region section. First and second sections of the jacket extend away from the sealing region section in first and second opposed directions, respectively. First and second sections of the metal shield layer extend away from the sealing region section in the first and second opposed directions, respectively. The outer sleeve surrounds the sealing region section. The sealant is disposed radially between the cable subcore and the outer sleeve, and engages the cable subcore to form a moisture barrier in the sealing region section between the first and second sections of the jacket. The jumper member electrically connects the first and second sections of the metal shield layer.

A pre-expanded cover assembly for protecting a cable splice connection including a cable, the cable including an electrical conductor surrounded by a cable insulation layer, includes a splice body assembly and a removable holdout. The splice body assembly includes a tubular, cold-shrinkable, electrically insulative, elastomeric splice body having an interior surface defining an interior passage. The splice body assembly further includes a tubular layer of a conformable medium pre-mounted on the interior surface of the splice body. The conformable medium is a flowable material having a high electrical permittivity. The splice body assembly is mounted on the holdout such that the holdout maintains the splice body in an elastically radially expanded state, and the holdout is selectively removable from the splice body to permit the splice body to elastically radially contract. The layer of the conformable medium is positioned and configured such that, when the pre-expanded cover assembly is positioned adjacent the cable splice connection, the holdout is removed from the splice body, and the splice body elastically radially contracts onto the cable splice connection, the layer of the conformable medium will be radially interposed between and engage each of the interior surface of the splice body and an opposing interface surface of the cable insulation.
