There is provided an HVDC cable accessory comprising an electric stress control layer which at one position is adapted to be connected to an HVDC cable, wherein the HVDC cable accessory is prefabricated, and the electric stress control layer comprises a thermoplastic elastomer.

A method of manufacturing a gasket for a double busbar is disclosed. The double busbar may be composed of two separate electrically insulated flat conductors. The conductors may be arranged one above the other. The double busbar may be placed in a mold cavity for molding the gasket. The mold cavity may be closed around the double busbar and filled with a sealing material. The introduced sealing material flows around the flat conductors, adhering to the flat conductors, and solidifying in the mold cavity to form a gasket molded to the double busbar.

A seal system for an oil-filled cable termination including a cable extending through each of a cable gland and a stress cone that is spaced apart from the cable gland. The seal system includes: a first oil seal layer surrounding the cable between the cable gland and the stress cone; a second oil seal layer overlapping and contacting the first oil seal layer; a first oil barrier layer overlapping and contacting an upper portion of the second oil seal layer; a second oil barrier layer overlapping and contacting a lower portion of the second oil seal layer, the second oil barrier layer spaced apart from the first oil barrier layer; and a heat shrinkable tube secured around the first and second oil barrier layers.

Provided is a wire harness in which waterproofness of an exposed conductor portion can be ensured, and even when at least one of insulated wires is exposed to a high temperature, a rubber stopper of a waterproofing terminal can be kept from coming off. An outer peripheral surface of an exposed conductor portion where partially exposed conductors of a plurality of insulated wires are joined together, and outer peripheral surfaces of coating material end portions adjacent to the exposed conductor portion, is continuously covered with a waterproofing agent. A gap between adjacent insulated wires is sealed with the waterproofing agent at the coating material end portions adjacent to the exposed conductor portion. At least one insulated wire of the plurality of insulated wires has a flow path through which gas flows, the flow path being created in gaps between strands that constitute a conductor of the insulated wire.

An exterior air-permeable member that includes a tube into which a wire can be inserted and in which a communicating hole is formed that is open to an outer-circumferential face of the tube; a body having an exterior fitted onto an outer periphery of the tube, and an attachment formed to be open to an outer periphery of the exterior and coming into communication with an inside of the tube via the communicating hole; an air-permeable film attached to the attachment; and a fixer that fixes the exterior to the tube.

An assembly for use with an oil-filled cable termination includes a cable gland, a cable received in the cable gland, and a stress cone received around the cable and spaced apart from the cable gland. The cable includes a central conductor and a polymeric insulation layer surrounding the central conductor. A lug is spaced apart from the stress cone and includes a barrel portion with the central conductor of the cable received in the barrel portion. An oil barrier system including an oil barrier layer surrounds the polymeric insulation layer of the cable between the stress cone and the lug.

A gland assembly includes a gland body (3) and a cap nut (5) connected by screw threads (25). A cable holding device (11) is received within the cap nut (5) and has a plurality of fingers (19) configured to apply a gripping force to a cable (7) extending through the gland assembly in response to a torque applied to the cap nut (5).The fingers (19) are configured to increase the gripping force on the cable (7) in response to a linear force applied to the elongate member.

The cable includes a central conductor and a polymeric insulation layer surrounding the central conductor. A lug is spaced apart from the stress cone and includes a barrel portion with the central conductor of the cable received in the barrel portion. An oil barrier system including an oil barrier layer surrounds the polymeric insulation layer of the cable between the stress cone and the lug.

A cable armor stop for preventing cable sheathing of an electrical cable from passing the armor stop while allowing electrical conductors of the electrical cable to pass therethrough has a body with an outer shell, the body having an interior cavity formed by an interior surface of the body, the cavity extending through the body between a front side of the body and a rear side of the body, the cavity reduced by a radially protruding member extending inwardly such that a terminating end of the radially protruding member is spaced a distance from an opposite side of the interior surface closest to the terminating end, the distance being less than a minimum outside diameter of the cable sheathing of said electrical cable. An electrical connector including such a cable armor stop.

A wire with terminal (1) includes a single-core wire (3), a connector terminal (2) and a seal (5). The wire (3) includes one conductor (31) and an insulation coating layer (32) covering the conductor (31). The wire (3) is formed with a conductor portion (310) that is part of the conductor (31) projecting from an end of the insulation coating layer (32). The connector terminal (2) is connected to the conductor portion (310) and arranged in an insertion hole (71) in a case (7). The seal (5) is mounted on an outer periphery of the conductor portion (310) and in the insertion hole (71) and closes a clearance (S1) between the inner periphery of the seal (5) and the outer periphery of the conductor portion (310) and a clearance (S2) between the outer periphery of the sealing member (5) and the inner periphery of the insertion hole (71).
