Provided is a wedge clamp for anchoring an end of a steel wire for further enhancement in workability upon use. A wedge clamp 1 for retaining a steel wire includes a first member 12 having a wedge shape and a second member 11 slidably fitting the first member 12 to restrain a steel wire by a pressure that generates based on the wedge shape of the first member 12, the wedge clamp 1 including an engaging portion (protrusion 124 and anchoring portion 113) enabling slidable fit between the first member 12 and the second member 11 while engaging the first member 12 and the second member 11.

A self-supporting overhead telecommunication/power cable includes a supporting portion and a transmission portion mutually arranged according to a figure-8 configuration. The transmission portion includes at a central position thereof, an optical fibre conductor and, at a radially outer position with respect to the optical fibre conductor, electrical conductors stranded around the optical fibre conductor. Preferably, the electrical conductors are grouped into sub-units which are stranded around the optical fibre conductor to provide a mechanical protection thereto.

Disclosed is a protector for a clip and line used to suspend aquaculture baskets or like equipment in water. In particular, the protector provides a sacrificial element between the clip and the line that is cheap to manufacture and easy to replace. While an application of the present invention is in oyster cultivation, it could equally well be applied to any process involving the line suspension of an article in water.

Described herein is a protective cover assembly for an electrical cable mounted on an insulator. The assembly includes an insulator cover including a cover body covering the electrical cable and the insulator and an electrically conductive arc diverter. The arc diverter is elongated in an axial direction that is parallel to a center axis of the electrical cable and is attached to an outer surface of the electrical cable at a portion of the electrical cable that is covered by the insulator cover such that a portion of the arc diverter is positioned below and covered by the insulator cover and another portion of the arc diverter extends past a terminal end of the insulator cover with an end of the arc diverter being spaced apart from the terminal end of the insulator cover in the axial direction.

A dead-end termination clamp including a cast body, a clamping end, and a connection end. The dead-end clamp may be scaled to support various size wires or cables. The dead-end clamp may be able to provide a support strength less than, equal to, or exceeding the breaking strength of a supported cable. A collet with a length, two ends, a central cavity and at least one helical slot running along the length of the collet. The at least one helical slot may have a varying width or pitch along the length. The at least one helical slot may terminate before reaching one or both ends. The collet may have one helical slots which runs the entire length of the collet. The collet may be substantially cylindrical or another shape. The center cavity may be substantially cylindrical or another shape.

Methods for connecting cables and cable connector accessories include inserting an end portion of the cable into a bore defined in a main body of the cable connector accessory, the cable connector accessory formed from an aluminum. Methods further include detonating an explosive, the explosive comprising a detonation cord surrounding an outer surface of the main body of the connector accessory. Detonation of the explosive compresses the main body around the end portion of the cable.

A cable support device includes a body having a first bracket and a cap having a first hinge. The cable support device further includes a transition piece disposed between the body and the cap. The transition piece includes an integrally formed body portion and oppositely-facing cap portion. The body portion has an inner surface defining a body portion groove extending longitudinally from a first end to an opposite end of the body portion. The body portion further includes a second bracket. The cap portion has an inner surface defining a cap portion groove extending longitudinally from a first end to an opposite end of the cap portion. The cap portion further includes a second hinge.
