A clamp for suspending a wire includes a housing having an inner support surface. The wire is disposed between the inner support surface and a keeper. The clamp further includes a fastening unit, including a first fastener and a second fastener attachable to the first fastener. The housing defines an opening extending in a direction along which the wire is received within the housing. After the second fastener is attached to the first fastener, the fastening unit is not removable from the housing. The fastening unit is movable, within the opening, between a first position and a second position. In the first position, the fastening unit cooperates with the keeper to decrease a distance between the inner support surface and the keeper. In the second position, the fastening unit does not cooperate with the keeper to decrease the distance.

A bracket device to secure one or more tail wires of one or more drop clamps to a utility pole. The bracket device includes one or more support ribs extending perpendicularly from the bracket base, and attached to one or more side supports. The support ribs and side supports define one or more retention regions along the side of the bracket based. A plurality of securing bolts can be cooperatively coupled to the side supports and define secondary retention regions. The securing bolts may be moved between an open position and a closed position. The bracket device can further comprise a top loop, which extends from the bracket base, and which can be coupled to additional wires. The bracket device can be secured to a utility pole or similar structure by a single fastening component, which is configured to pass through the cavity of the bracket base.

The present invention discloses a bracket (1) with enhanced loadbearing capacity for power transmission poles wherein protrusions (52) extending from loadbearing plates (12, 13) are inserted into horizontal and parallel slots made in the base plate (11), and protrusions (52) are bent behind the base plate (11). After insertion and bending, protrusions (52) portion of loadbearing plates (12, 13) are secured by welding on both sides namely the front and rear of the base plate (11). The bending of protrusions of loadbearing plates (12, 13) behind the base plate (11) and welding it on both sides considerably improve the strength of the joint, and thus the loadbearing capacity of the bracket is significantly enhanced.

A cable-clamp system comprises a base structure and a clamp. The base structure is located within an electronic chassis. The base structure includes an upper region, a first side region, and a second side region. The upper region includes a plurality of cable-receptor cavities for receiving the cables. The first side region includes an opening, and the second side region includes a slot. The clamp includes an engagement surface, a first end, and a second end. The first end includes a hook for insertion into the opening to allow pivoting movement of the clamp relative to the base structure. The second end includes a plunger for retention within the slot. When the clamp pivots downwardly to cause the engagement surface to engage the cables, the plunger is retained within the slot to maintain a clamping force on the cables between the base structure and the clamp.

A cable spacer includes first and second angle arms each having a cable engaging end at one end and a flat tab portion at an opposite end having a connecting tab and an aperture to connect the arms to each other. An insulator extends between and connects the angle arms at their respective connecting tabs. The insulator has a non-conductive core. The angle arms and insulator mounted to each other define a spacer plane. A bottom arm is mounted to and depends from insulator. The bottom arm is mounted to the insulator to sway into and out of the spacer plane. A clamp secures the cable spacer to a messenger and includes upper and lower clamp portions. The upper clamp portion mounts to the messenger and the lower clamp portion mounts to cable spacer angle arms. The lower clamp portion is rotatable relative to the upper clamp portion.

An apparatus and method of assembling a bracket assembly on a cross-arm is disclosed. The bracket assembly comprises a bracket, adjustable plate, first accessory frame, and second accessory frame. First accessory frame and second accessory bracket are coupled to the bracket with captive nuts. The bracket assembly is secured to a cross-arm by the adjustable plate, which is coupled to the bracket with at least one guide pin and an adjustable plate bolt.

An eddy current energy-dissipating spacer is mainly composed of a spacer frame, a conductor clamp and energy-dissipating elements. The eddy current energy-dissipating spacer not only provides the function of an ordinary spacer, but also reduces the vibration of the transmission lines; and at the same time, can effectively reduce the vibration of the transmission lines, especially the torsional vibration by adopting the eddy current and viscoelastic material for energy dissipation; improves the eddy current strength by adjusting the gear radius ratio, thus increasing the damping force; can adjust the damping parameters by adjusting the magnetic field strength of the permanent magnet; can produce long-term stable vibration reduction effect by adopting the permanent magnet to provide continuous magnetic field without additional external energy input; can effectively avoid the magnetic flux leakage of magnetic circuits by adopting the magnetic material.

An anti-rotation clamp and method of use may include a bolt having a threaded body along which a stabilizer moves relative to the threaded body, a stabilizer and an engagement member which engages the stabilizer to prevent relative rotation between the stabilizer and the engagement member as the threaded body is rotated.

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.
