An insulator includes an end fitting and a connecting device disposed on the end fitting for connecting the insulator to a suspension device. The insulator also includes an additional operating device. The end fitting and the connecting device are formed in one piece. An arrangement is also provided for dissipating overvoltage using the insulator according to the invention.

A complete set of tension backup device for carbon fiber wire, consisting of a backup tension device, a performed armor rod, a parallel hanging plate, an adapter base, a wire drawing device, a support damper clamp, a U-shaped pulling ring, a triangular hanging plate, and a tensioning device. The backup tension device is a backup strain clamp in a wedge-shaped structure. The support damper clamps are provided on carbon fiber split wires between an original strain clamp and the backup tension device, and arranged at intervals of 3-4 meters.

A bundle lifter for lifting a sub-conductor bundle having a plurality of spaced-apart sub-conductors, includes a base platform adapted for rotational mounting onto a single point conductor lifter, four sub-conductor wire cages mounted on the platform to support a sub-conductor thereon, each wire cage adapted to releasably hold a single sub-conductor and to swivel relative to the platform, wherein when the wire cages are positioned under the sub-conductor bundle, the wire cages are swivelled to align their corresponding rollers with a corresponding sub-conductor for rolling support of the sub-conductor on the roller as the bundle lifter is elevated on the support upwards from under the sub-conductor bundle to simultaneously pick each sub-conductor in the bundle into its wire cage for translation of the bundle from an original position to a new position spaced apart from the original position.

An attachment tool for attaching a tie tube to a wire includes a body and a first engagement portion extending away from the body. The first engagement portion releasably engages a first end of the tie tube for attachment of the first end of the tie tube to the wire. A second engagement portion extends away from the body and releasably engages a second end of the tie tube for attachment of the second end of the tie tube to the wire after attachment of the first end of the tie tube to the wire. A coupling structure is connected to the body, the coupling structure coupling to a hot stick.

A clamp for supporting an electrical conductor on a structure and providing electrical continuity between the electrical conductor and the structure is provided. The clamp can include a mounting member with a through-hole and a strap, that can be configured to extend around the structure, coupled on one end to a first side of the mounting member and having a free end removably coupled to a second side of the mounting member. The clamp can include a clamping member with a through-hole and a main bolt extending through the through-holes of the mounting member and the clamping member. The main bolt can have a footer configured to contact the structure, which can be movable between a first configuration in which the footer is nested within a pocket of the mounting member and a second configuration in which at least a portion of the footer is positioned outside of the pocket.

A dielectric cover for an insulator, supporting a high voltage conductor in an electrical distribution system, has holes for receiving retaining pins. The retaining pins are used to secure the cover over the insulator and conductor. Arched fenders, which may be circular or have a bottom opening, extend out from the cover and overlie the holes and ends of the pins. The fenders prevent birds roosting on the pin, increase the dielectric surface length between the top of the cover and the electrical conductor above the pins, and protect the pins from contamination issues which would reduce the dielectric properties of the pins. Contamination issues include birds defecating on the pins, which can create a conductive path between the bird and the inside of the cover, and atmospheric moisture such as rain, snow, and ice on the pins. Thus, wildlife is protected from electrocution.

An overhead electrical infeed system includes an overhead mount surface, an electrical cord coupled to the overhead mount surface, an electrical outlet assembly coupled to a distal end portion of the cord having a proximal end portion mounted to the overhead mount surface and a distal end portion spaced from the proximal end portion. At least a portion of the weight of the electrical outlet assembly is supported by the electrical cord. A retractor is positioned along the electrical cord and is operable to raise the electrical outlet assembly or to retain the electrical outlet assembly at a selected elevation. An electrical outlet is electrically energized by the electrical cord and is mounted to the electrical outlet assembly, to provide users with access to electrical or data signals.

An electrical component cover includes a central portion, a first end portion and a second end portion and one or more flexible portions between the central portion and the first end portion or second end portion to enable the electrical component cover to flex and thereby facilitate varying geometries in power lines attached to insulators.
