A cable splice assembly includes a tubing encapsulated cable, an electric submersible downhole cable, where the tubing encapsulated cable and the electric submersible downhole cable are tape-spliced through a pair of respective contacts, and a thermoplastic insulator to seal the tubing encapsulated cable. A shell contains the tape-spliced tubing encapsulated cable and the electric submersible downhole cable and multiple layers of sealant tape are wrapped around at least the tubing encapsulated cable and the thermoplastic insulator inside the shell, where a number of layers of the sealant tape is selected to create a pressure blocking seal inside the shell.

A high-voltage self-aligning push to mate electrical interconnect device is provided. The electrical interconnect device includes a housing with a mating end and a receiving end. The interconnect also includes an insulator bushing configured to be affixed to the receiving end of the housing. The interconnect also includes a center pin disposed within the housing. The center pin extends from the mating end of the housing to the receiving end of the housing. The interconnect also includes a connector socket disposed within the insulator bushing and which is in electrical communication with the center pin. The interconnect also includes an alignment sleeve including a chamfered mating funnel defining a void configured to accept and surround the housing and at least a portion of insulator bushing.

A harness member includes a cable, a housing with an insertion hole through which the cable is inserted, a heat-shrink tubing covering the housing and the cable exposed on one side from the insertion hole, and a hot melt adhesive to seal between the heat-shrink tubing and the cable and between the heat-shrink tubing and the housing. A recess is formed on the housing so as to be recessed from an outer circumferential surface covered with the heat-shrink tubing. At least a portion of the hot melt adhesive melted between the outer circumferential surface of the housing and an inner circumferential surface of the heat-shrink tubing has flowed into the recess.

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.

The invention relates to insulated submarine cables including conductive cores (3a, 3b) and insulating material (5a, 5b) surrounding the conductive cores (3a, 3b). Such an insulated cable includes a first length and a second length. The cable has a roughly constant core (3a) cross-sectional area A1 and a roughly constant insulating material (5a) thickness T1 along the first length, and a different roughly constant core (3b) cross-sectional area A3 and/or a different roughly constant insulating material (5b) thickness T2 along the second length. The cable may include one or more other lengths which join the first length and the second length to one another.

A termination arrangement for securing an overhead electrical cable to a dead-end structure such as a dead-end tower. The termination arrangement includes a compression sheath that is configured to be disposed between a strength member and the conductive strands of the overhead electrical cable. The compression sheath mitigates damage to the strength member that may occur when an outer metallic sleeve is compressed around the conductive strands and the conductive strands are compressed against the strength member. The arrangement is particularly useful for securing overhead electrical cables having a composite strength member to a dead-end structure.

Provide is a protective component, including a tubular sidewall being elastic and encloses to form a through hole for receiving the wire box connector; a limiting portion provided on an inner wall surface of the tubular sidewall and configured to clamp a recess on the wire box connector; and a tubular protective portion being elastic and is connected to the tubular sidewall to cover an end portion of the tubular sidewall. The protective component of the present disclosure may prevent the protective component from falling off from a wire box connector after mounting to improve mounting efficiency of the wire box connector and may reduce micro-cracks caused by colliding with a solar cell module.
