    摘要: The present invention relates to replacing conductors in a high-voltage power transfer system. The method provides, for example, a method for maintaining sections of electrically conductive phases in a three-phase power conductor line, wherein the three phases are parallel and spaced apart in an ordered sequence. The phases are strung between support structures and supported above the ground. Maintenance work, which include replacement or repair, is performed on sections of the three phases without interrupting a power load in any one of the three phases and without transposing the relative positions of the phases out of their ordered sequence.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.
