摘要： An electrical isolator includes a flexible non-electrically conductive membrane and an inelastic flexible dielectric member journaled in the membrane and extending from the first end of the membrane to the second end of the membrane. First and second couplings are mounted to the ends of the dielectric member. The ends of the membrane are mated in sealed engagement with the couplings so as to fluidically seal the ends of the membrane and the dielectric member within the membrane. The membrane is filled with a dielectric fluid so as to displace any air in the membrane and the dielectric member. The couplings are adapted to couple to objects at opposite ends of the electrical isolator.

摘要： A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a cooperating hot-stick. The lock-out employs a clutch which prevents the translation of the clamping members relative to one another until the clutch is disengaged. The cooperating hot-stick is required for the disengagement of the clutch.

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.

摘要： A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a hot-stick. A clamping member cooperates with a frame having an arm, and is selectively biasable by a user to translate the clamping member relative to the frame to clamp a conductor between the clamping member and arm. The lock-out cooperates with the clamping member to prevent the translation of the clamping member unless in the presence of an insulating tool such as a hot-stick.

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.
