Abstract: A temporary insulated conductor guard structure is mountable on an electrical insulator. The electrical insulator is mounted on the distal end of a crane or truck boom. The conductor guard structure includes a U-shaped frame having a horizontal elongate beam and a pair of stub arms upwardly extending from opposite ends of the beam. Elongate rigid, electrically conductive rollers are rotatably mounted to each of the stub arms and the beam so as to form an electrically conductive rolling surface extending around the interior of the U-shaped frame for rotationally supporting sagging electrical conductors thereon.

Abstract: An intelligent electrical conductor installation system includes a puller sub-system, a tensioner sub-system, and a running board. The pull sub-system is configured to provide a pulling force to a pull rope connected on one end to the running board. The tensioner sub-system is configured to provide tension to the one or more conductors connected to the running board during installation of the conductors. The running board is connected to the pull rope on a first end, and configured to be connected to one or more conductors on a second end, wherein the running board includes one or more sensors configured to sense attributes of the conductor pull operation.

Abstract: The invention relates to an anchor clamp for the termination of an overhead cable, which comprises a body (1), a clamp handle (3) fixed to the body and wedge parts (2) moving in relation to the body, between which the overhead cable (5) is pressed when pulling directed at the cable moves the wedge parts (2) in relation to the body (1). On the clamp is arranged a stay tightened (4, 4') located at the wider end of the wedge parts (2), or in front of the wider end, and thus forms a stopper means, which moves the wedge parts (2) in the direction of pulling due to the pulling of the cable. The stay tightened (4, 4') can be made, by means of a clamping screw (4a, 4b) or similar clamping means, to grip around the cable (5), pressing directly on the conductor metal, with a coated cable, through the cable insulation.
