A joint for electric power cable, preferably operating at low and medium voltage, filled with a resin obtained in situ by contemporaneously cold setting a composition containing a (meth)acrylate ester of an alkanol having from 6 to 20 carbon atoms with a curing agent acting also as a tackifying agent and selected from the group consisting of a urethaneacrylate and an epoxylacrylate oligomer having a functionality from 1 to 6 in amounts ranging from 0.1 parts to 10 parts by weight per 100 parts by weight of the methacrylate ester. A kit for preparing a cable joint includes the joint and the composition for preparing the cured resin. The resin contained in the joint does not exhibit cold flow and therefore does not flow from the cable joint.

The present relates to a washable interconnection patch, a connection assembly, and an intelligent washable garment equipped therewith. The patch receives and interconnects wires to a cable. The patch comprises two matching pieces interlocking together so as to define there between two opposite apertures. One of the apertures is adapted to receive and hold the wires, and the other aperture is adapted to receive and hold the cable. One of the two matching pieces defines on an interior face a channel to interconnect the wires to the cables. The connection assembly comprises a male connector and a female connector. The male connector defines a series of independent connection points along a length thereof. The female connector is adapted to receive the male connector, and defines along a length of an inner surface thereof a series of contact points. When the male connector is inserted within the female connector, the connection points and the contact points are aligned and in contact together.

A power distributor including a first conductive coupling device electrically coupled to a bare-wire non-terminating section of a first conduit. A second conductive coupling device is electrically coupled to a terminating end of a second conduit. The first conduit is a larger gauge than the second conduit. A fuse electrically connects the first conductive coupling device and the second conductive coupling device. A housing encases the first and second conductive coupling devices and the fuse.

Disclosed herein is a gel seal including a volume of gel between first and second end plates. The first and second end plates have one or more cable ports with a central longitudinal axis extending through the first end plate, the volume of gel, and the second end plate. The cable port has a first, circular cross-sectional profile in the first and second end plates for receiving a round cable and a second, elongate cross-sectional profile in the first and second end plates for receiving a flat cable.

A branch box (100) includes: a branch portion (21) branching a power path (205A) into at least two branch paths (206A, 207A); a fuse (60) located on at least one of the branch paths; a conductive member (33) connecting the branch portion and the branch path having the fuse; a first housing portion (11) receiving the fuse and closing its opening with a lid portion (81) to define a housing space; and a second housing portion (12) receiving the branch portion. The first housing portion is sealed with a first sealing material (85) filling a gap between the lid portion and the opening and is out of contact with the fuse. The second housing portion is sealed with a second sealing material (86) independent from the first sealing material. The conductive member passes through a partition wall (25) separating the first housing portion and the second housing portion.

Power trunk conductors 30 of a trunk cable 12 and power branch conductors 37 of a branch cable 13 are electrically connected to each other by a first trunk-side bus bar 56, fuses, and a first branch-side bus bar 60. Signal trunk conductors 31 of the trunk cable 12 and signal branch conductors 38 of the branch cable 13 are electrically connected to each other by the relay bus bars 64.

An HVDC power cable joint assembly for jointing more than two power cables, including: a connection body including: a multi-branch conductor having at least two branches and a stem, a multi-branch conductor insulation system including: a connection body inner semiconducting layer arranged radially outside of the multi-branch conductor, a connection body insulation layer arranged radially outside the connection body inner semiconducting layer, a connection body outer semiconducting layer arranged radially outside the connection body insulation layer, N power cables, where N is the number of branches plus one, each power cable having a conductor, and a power cable insulation system surrounding the conductor, N power cable joints, each connecting a branch or the stem to a respective power cable, wherein each power cable joint includes: a conductor joint between one of the branches, or the stem, and a conductor of one of the power cables, a joint insulation system arranged around the conductor joint, the joint insulation system including a deflector layer, a field grading layer, a joint insulation layer and a joint insulation system outer semiconducting layer, and an outer cover housing the joint insulation system, and an external metal casing accommodating the connection body.

A backfilling protection structure for underground installation of a power cable joint, including: a lower casing part forming a base of the backfilling protection structure and configured to be laid on soil, an upper casing part configured to be arranged on top of the lower casing part, wherein the lower casing part and the upper casing part are configured to be attached to each other to form an elongated body, wherein the body defines a channel for receiving a power cable joint, wherein the channel extends through the backfilling protection structure from a first end opening at a first axial end of the backfilling protection structure to a second end opening at a second end of the backfilling protection structure opposite to the first end, wherein the upper casing part is provided with a plurality of top openings distributed along the length of the body and extending into the channel, and a plurality of grids covering a respective top opening, each grid being configured to filter out solid objects larger than a predetermined size from entering through the respective top opening into the channel but enabling sand to enter the channel to bury the power cable joint inside the backfilling protection casing.
