A dead-end clamp assembly for a utility conductor includes a clamp body having a base with a front end and a rear end, a first jaw guide extending from the base, and a second jaw guide extending from the base. The base, first jaw guide, and second jaw guide at least partially define a trough. A first jaw movably engages the body and a second jaw movably engages the body. The first jaw engages the second jaw such that the first and second jaws move together. A sag eye extends from the clamp body. The sag eye has an opening configured to receive a hotstick. A clevis connector extends from the rear end of the clamp body. The clevis connector is configured to receive a clevis pin so that the clevis pin is positioned below the trough.

A termination arrangement for securing an overhead electrical cable and a method for securing an overhead electrical able. The termination arrangement includes a longitudinally-extending sheath having a high tensile modulus that is configured to receive a strength member of the overhead electrical cable therein. When a connector body is crimped over the strength member, the sheath substantially reduces the tensile strain experienced by the strength member and reduces the risk of fracturing the strength member.

Electrical line hardware such as termination arrangements and splices for use with overhead electrical cables that enable the interrogation of the overhead electrical cables through the hardware. The hardware includes at least one port to facilitate access to the strength member of the electrical cable so that interrogation instruments may operatively couple to the strength member and to interrogation elements such as optical fibers associated with the strength member. The interrogation may occur after the overhead electrical cable has been fully tensioned and secured by the hardware, e.g., secured to a support tower.

A cable clamp includes a shell having a shell base, a first sidewall and a second sidewall forming a channel extending in a first direction to receive a cable therein. A wedge resides between the first and second sidewalls and includes a wedge base facing the shell base. A shim resides between the wedge base and the shell base, and the cable fits between the shim and the shell base. Movement of the shell relative to the wedge causes the cable to engage more tightly between the shim and the shell base. In one embodiment, a blade element resides between the shim and the shell base. The blade may be a separate element from the shim or attached to or integrally formed with the shim. The wedge may include a recessed area or a cutout portion to accommodate the blade. A cutting edge of the blade element faces toward the cable and will cut the cable in response to an excessive force along the first direction being applied to the cable within the channel.

A bracket for suspending multiple line segments at an elevated location is disclosed. The bracket has a back portion to engage against a supporting surface at the elevated location. The back portion has a left segment and a right segment. The bracket has at least one of a left arm extending from the left segment or a right arm extending from the right segment. The bracket has at least one of a first left seat extending from the left arm, a second left seat extending from the left arm, a first right seat extending from the right arm, or a second right seat extending from the right arm. At least one of the multiple line segments are supported by at least one of the first left seat, the second left seat, the first right seat, or the second right seat.

A clamp assembly includes a body member having a first and second ends. A cable groove is formed in the body member between the first and second ends thereof to receive a conductor. A keeper is connected to the body member and has a lower surface to engage the conductor received in the cable groove. A threaded fastener connects the keeper to the body member. A biasing member is disposed between the keeper and the body member on the threaded fastener to bias the keeper in a direction away from the body member.

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 method for connecting a conductor and a conductor connector accessory includes inserting an end portion of the conductor into an interior of a tube, and inserting the tube into an interior of a barrel. The barrel defines a plurality of radial passages extending between an outer surface of the barrel and the interior of the barrel. The method further includes providing a plurality of lobes, each of the plurality of lobes disposed within one of the plurality of passages. The method further includes inserting the barrel into an interior of an outer shell, and compressing the outer shell, barrel, lobes, tube and end portion together.

Provided is a fastening structure of a clamp for supporting a power line and an insulator, which includes a fastening means for preventing an end of the insulator from being separated from the clamp in a state in which the end of the insulator is disposed between an arm part and an auxiliary arm part of the clamp. The fastening means includes a pin fitted to pass through through-holes of the arm part and the auxiliary arm part of the clamp and the end of the insulator and an elastic latching rod mounted on the pin and elastically curved to pass through each of the through-holes and to be restored in its original shape, thereby preventing the pin from being separated. The elastic latching rod is mounted on the pin and has the form of a coil spring where both ends of the elastic latching rod protrude from the pin.
