A support core for an elastic sleeve comprises a first cylindrical section disengagably connected to a second cylindrical section. Each cylindrical section has an annular sidewall made up of a plurality of interlocking concave plates extending longitudinally along a portion of the support core between a abutment end and a distal end. The abutment end of each cylinder section includes a generally helical edge. The plurality of concave plates comprises a top and bottom surfaces, having two opposing longitudinal edges extending between said surfaces on opposite sides of the concave plate. Each of the longitudinal edges comprises an interlocking feature that configure to connect to a mating feature of at least one other concave plate to form one of cylindrical sections of the support core.

An insulation system for jointing of high voltage conductors has an inner layer made of a crosslinked first polymeric semiconducting material, an intermediate insulating layer made of a thermoplastic polymeric insulating material, and an outer layer made of a second polymeric semiconducting material. The insulation system is adapted for surrounding the electric conductor joint.

A dispenser apparatus (10) for dispensing curable liquid material into a space in a cable gland is disclosed. The apparatus comprises a housing (12) for separately storing of components of a curable liquid material and provided with a respective first outlet (14) for each component. A mixing chamber (16) mixes the components to cause curing of the curable liquid material and has an inlet (18) for receiving the components from the first outlets, and a second outlet (20) for the mixed components. A plunger (22) urges the components out of storage chambers of the housing via the first outlets and into the mixing chamber via the inlet. The dispenser apparatus is adapted to be located in a body of a cable gland such that the mixed components are dispensable from, the second outlet into a space defined by the body and a cable extending through the body.

A cable joint assembly and a method for assembling such a cable joint assembly. The cable joint assembly joins at least two cable ends, said cable joint assembly comprising a cable joint defining an interior space into which in use said at least two cable ends extend and are joined and which in use is filled with a liquid, wherein said cable joint assembly further comprises a barrier element that is placeable in said interior space in such a manner, that in use the barrier element extends around the at least two cable ends at least in an area where the at least two cable ends are joined.

A butt closure base includes a base housing defining a plurality of cavities. A first gel is disposed in each of the plurality of cavities. The butt closure base further includes a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities. Each of the plurality of wedge assemblies includes an outer cover, a second gel, and a main pressure plate in contact with the second gel. The main pressure plate is movable along a longitudinal axis to apply pressure to the second gel. Each of the plurality of wedge assemblies further includes a latch assembly. The latch assembly includes an adjustable tab and a stop member movable between a first position which limits movement of the adjustable tab and a second position in which movement of the adjustable tab is not limited by the stop member.

Various embodiments of the teachings herein include an electrical device comprising: a cable wire; a cable insulation arranged around the cable wire such that a section of the cable wire at least partially longitudinally protrudes out of the cable insulation; a heat-shrink tube at least partially arranged around the cable insulation and at least partially around the section of the cable wire; and a sealing material at least partially inside the cable insulation thereby sealing any gaps between the cable wire and the cable insulation.
