    Abstract: An implosion shield of ballistic fabric adapted to mount so as to surround an implosion sleeve or dead-end on a power line. The implosion shield may be wrapped or formed as an envelope or tent including one piece and folded around the implosion sleeve or dead-end and secured with fasteners. A method of installing the implosion cover may include installing an implosion sleeve or dead-end on a power line, and then installing the implosion shield around the implosion sleeve or dead-end, by wrapping the implosion shield around the implosion sleeve or dead-end, or by securing an envelope implosion shield over the implosion sleeve or dead-end, or by draping the shield over the implosion sleeve or dead-end, or by mounting the shield on a frame over the implosion sleeve or dead-end, then detonating the implosion sleeve or dead-end. The implosion shield attenuates shock, pressure and sound waves from the detonation.

    Abstract: An anti-rotation device is provided for stringing a cable or wire while reducing a twisting moment of the cable or wire as it is strung. The device includes a tow component, having multiple tow sections pivotally connectable end-to-end. A plurality of insulated weighted tail components are suspended so as to hang from the tow component. Each of the insulated tail components include weighted tail sections releasably connectable end-to-end to one another. At least one electrically insulated tail section is provided in each insulated tail component between the tow component and the weighted tail sections. The tail components are constrained to only articulate relative to the tow component in the single plane of bending of the tow component.

    Abstract: A grounding clamp uses a spring driving a piston mounted movable jaw as a safety lockout. The movable jaw and a fixed jaw, which may include teeth, form a conductor clamp. The ground clamp mounts on the end of a hot stick to provide for electrically insulated remote operation of the ground clamp by a lineman holding the hot stick and pulling on, or releasing, a lever arm on the hot stick. The system provides increased safety for the lineman as the spring providing the spring loading of the clamp has a high spring force to overcome, thus providing the lockout. The lever arm on the hot stick tool provides mechanical advantage to overcome the spring force and thus release the lockout. The lineman cannot usefully operate the ground clamp manually without the hot stick due to spring force lockout.

    Abstract: A remotely controlled unmanned aerial device for use in proximity or in contact with high voltage powerlines, includes an unmanned aerial vehicle and an electrically conductive shield forming part of or operatively coupled to so as to encapsulate the unmanned aerial vehicle. When in the presence of a high voltage powerline, the unmanned aerial vehicle either when bonded-on or within the corresponding magnetic fields of the powerline, so as to transfer the powerline potential in whole or in part to the unmanned aerial vehicle, electrically energizes the conductive shield around the unmanned aerial vehicle while leaving components of the unmanned aerial vehicle within the shield substantially electrically unaffected by the voltage potential.

    Abstract: A conductor lifter adapted to be mounted to a tower for temporarily supporting an energized conductor comprises a support arm having a base end and an opposite cantilevered end and a crank arm pivotally mounted on the cantilevered end, the crank arm having lower and upper crank arms. A first actuator is coupled to the support arm, and an elongate member is mounted to, so as to extend between, the upper crank arm and a first driver of the first actuator so as to rotate the crank arm about the pivotal coupling when the first actuator is actuated. A lower end of the lower crank arm is selectively elevatable by a second actuator relative to the upper crank arm so as to elevate a conductor when held by a conductor retainer on an insulator mounted to the lower crank arm. A method for using the conductor lifter is also provided.

    Abstract: A method of using a temporary conductor as a re-usable tool in maintaining, repairing or re-conductoring at least one energized phase, includes stringing the temporary conductor between support structures at either end of a first section, then energizing the said temporary conductor by bringing the temporary conductor to the voltage potential of the phase and electrically paralleling the temporary conductor with the energized phase, de-energizing and then maintaining, repairing or reconductoring the de-energized energized phase, re-energizing and electrically paralleling said energized phase, de-energizing and removing the temporary conductor for later re-use as the re-usable tool in a second section of the energized phase.

    Abstract: A boom mountable breaker system and a method of using same for interrupting electrical transmission through a portion of an energized conductor downstream of a desired break location. The method includes: mounting the jumper onto the energized conductor across the desired break location so as to form an electrically conductive first parallel electrical path; installing an in-line opener in the energized conductor at the desired break location on the energized conductor; positioning the breaker at the desired break location on the energized conductor, and electrically connecting the breaker, while open, across the desired break location and across the opposite ends of the jumper so as to form a second parallel electrical path when the breaker is closed; closing the breaker to thereby complete the second parallel electrical path; removing the jumper from across the desired break location; and, opening and then removing the breaker.
