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.

An apparatus and method for enabling removable coupling of conducting lines in a powerline assembly is disclosed. In one embodiment, a dead-end shoe apparatus is disclosed that comprises a capping mechanism, coupling mechanism, and connection clamp, the connection clamp facilitating the removable coupling of conducting lines of variable diameters to the apparatus. In another embodiment, a method of selectively transmitting electricity in a powerline assembly is disclosed, wherein conducting lines are removably coupled to dead-end shoe apparatuses to facilitate the transmission.

A support device for supporting a wire includes a first support portion. A second support portion includes a first leg portion and a second leg portion that extends linearly and is attached to the first leg portion and to the first support portion. A third support portion includes a third leg portion having a third inwardly facing surface, which faces towards the third axial opening, and a third outwardly facing surface, which does not face towards the third axial opening. The third inwardly facing surface and the third outwardly facing surface have a different surface roughness. A fourth leg portion has a fourth inwardly facing surface, which faces towards the fourth axial opening, and a fourth outwardly facing surface, which does not face towards the fourth axial opening. The fourth inwardly facing surface and the fourth outwardly facing surface have a same surface roughness.

An assembly component of a compression joint member that connects a power-transmission line to a connection target, includes a core portion compression member including a housing hole that houses an end portion of the core portion, and a compression portion that is compressed for compressing and connecting the end portion of the core portion housed in the housing hole; and a conductive portion compression member that houses an end portion of the conductive portion and the core portion compression member, and is to be compressed with the end portion of the conductive portion and the core portion compression member, wherein the compression portion includes an inclined portion provided at an opening side of the housing hole and whose outer diameter becomes smaller toward the opening side of the housing hole.

A bracket device to secure a tail wire of a drop wire clamp to a structure including a base having a surface. The bracket device further includes a retention hook having a first end, a second end, and retention region defined between the first end and second end. The first end of the retention hook is coupled to the base surface, and the second end of the retention hook is disposed at a predetermined distance from the base surface to define a gap therebetween having a width. The bracket device further includes a locking nut that is cooperatively coupled to the second end of the retention hook and adapted to move between an unlocked position to permit a wire to enter the retention region and a locked position in which a wire is retained by the retention hook in the retention region by a reduction of the gap width.

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 structure that is configured to be disposed over the individual composite rods of the strength member. The compression sheath structure 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.

The technology relates to an electric current conducting assembly, more specifically with the incorporation of a dead end shoe.

A cable splice includes a casing having a central portion and a first end including a first aperture. The casing defines an interior cavity. A guide assembly extends through the first opening into the interior cavity. A first clamp member is positioned in the interior cavity and moveable between a loading position and a terminated position. A first biasing member biases the first clamp member toward the terminated position. A carrier is positioned in the interior cavity between the first biasing member and the central region. A second clamp member is positioned in the carrier and moveable with respect to the carrier.
