The process and apparatus for tension stringing a conductor through above-ground supports uses a length of rope affixed to the conductor wound on the tensioning machine and pulled by the puller machine. Each of the first and second stringing apparatuses includes an onboard control system which controls each of the first and second stringing apparatuses in pulling mode or in tensioning mode. Each of the first and second stringing apparatuses includes a motor/regenerative brake or other means of inducing tension into the conductor. Each of the machines includes a wireless transceiver which is hard-wired to said onboard control systems. A first operator resides on the puller machine and selects the machine as a puller machine operating in pulling mode using an onboard control system. An observer resides on the tensioner and selects the second machine to be the tensioner. Each of the wireless transceivers communicates with the other wireless transceiver enabling control of both the machines by the onboard control system of the puller machine.

The present invention includes a flexible jumper jig which is reconfigurable to replicate the end positions of a flexible jumper as it would be on an installed substation. According to a further preferred embodiment, an exemplary system of the present invention may include a framework forming three orthogonal axes and repositionable tooling mounts for end fittings. According to another aspect of the present invention, an x-axis oriented rail may preferably hold a tooling mount which is configurable to be rotated about its axis to allow for alternate tooling mount orientations. Further, a y-axis oriented rail may be perpendicular to the x-axis rail and may be fixed. Still further, a z-axis oriented rail may be perpendicular to and slide along the y-axis rail. Additionally, a second tooling mount may be attached to the z-axis rail.

An assembly component of a compression joint member that connects a power-transmission line to a connection target, includes a core portion compression member including a housing hole that houses an end portion of the core portion, and a compression portion that is compressed for compressing and connecting the end portion of the core portion housed in the housing hole; and a conductive portion compression member that houses an end portion of the conductive portion and the core portion compression member, and is to be compressed with the end portion of the conductive portion and the core portion compression member, wherein the compression portion includes an inclined portion provided at an opening side of the housing hole and whose outer diameter becomes smaller toward the opening side of the housing hole.

A support device for supporting a wire includes a first support portion. A second support portion includes a first leg portion and a second leg portion that extends linearly and is attached to the first leg portion and to the first support portion. A third support portion includes a third leg portion having a third inwardly facing surface, which faces towards the third axial opening, and a third outwardly facing surface, which does not face towards the third axial opening. The third inwardly facing surface and the third outwardly facing surface have a different surface roughness. A fourth leg portion has a fourth inwardly facing surface, which faces towards the fourth axial opening, and a fourth outwardly facing surface, which does not face towards the fourth axial opening. The fourth inwardly facing surface and the fourth outwardly facing surface have a same surface roughness.

A tensioning device includes a circular spring, and a pulley rotatably connected to the circular spring. The pulley includes a circumferential groove, which has a V-shaped cross-section defined by two lateral converging walls. The pulley also includes a flexible rope having a variable cross section, extending between a first end connected to the pulley and a second end intended to be connected to the cable. The pulley is rotatably movable around an axis, between a first position in which the flexible rope is arranged in the circumferential groove around the axis, and a second position in which the flexible rope is unwound.

Systems and methods for tensioning an electrical cable adapted to be manipulated by one or more remotely operated robotic appendages. Tensioners mounted to a rigid object configured to adjust the tension of a connecting line attached to an electrical cable such that the tension of the connecting line is applied to a length of the electrical cable such that another portion of the electrical cable becomes slack, thereby allowing one or more robotic appendages to remove, replace, repair, or conduct any alteration or modification to said electrical cable or to a rigid object that supports the electrical cable.
