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 direct current (DC) two phase power conductor line, wherein the two phases are parallel and spaced apart. 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 two phases without interrupting a power load in any one of the three phases and without transposing the relative positions of the phases.

A system is provided for use with an insulated boom section of a bucket truck. The system includes a source of high volume and pressure, dry air; one or more interior air diffusers connected to the source of high volume and pressure, dry air to direct the air into an interior of the insulated boom section. One or more exterior air diffusers connected to the source of high volume and pressure, dry air direct the air to along an exterior surface of the insulated boom section. A method is also provided for cleaning or drying both the interior and exterior surfaces simultaneously of an insulated boom section of the boom of a bucket truck. The boom of a bucket truck is further provided in another aspect that includes at least one insulated boom section, a source of high volume and pressure, dry air, one or more interior air diffusers and one or more exterior air diffusers. A pre-heating air heater may be removably mounted into the boom.

Load-bearing apparatus/systems for location in the vicinity of energized power lines are provided. The apparatus includes a base member. The base member has an upper layer and a backing surface layer. An uppermost surface of the upper layer is adapted to support on it at least power line workers and/or related stringing equipment. At least the uppermost surface of the upper layer is adapted to be electrically conductive. Methods for forming the apparatus are also provided.

Electrically conductive surface and a process for producing the same

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.

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.

Live conductor stringing, maintenance and repair method

An electrical isolator includes a flexible non-electrically conductive membrane and an inelastic flexible dielectric member journalled 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.

Flexible electrical isolation device

A continuous processing system and method for the continuous processing of an electrical conductor cable having aluminum strands encasing a steel core directly from a puller or from a puller and reel, simultaneously or on-the-fly during substantially the entirety of a reconductoring or re-stringing of the cable, wherein such cables are used for power lines or for static wires. The system is adapted to cooperate with a pulling machine. The pulling machine may be formed integrally within the system or may be a conventional pulling machine which cooperates with the system. The processing system runs continuously, substantially without interruption, during the pull of all of the cable from the pull zone of the reconductoring or restringing.

The couplings are adapted to couple to objects at opposite ends of the electrical isolator.

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.

An electrical isolator includes a flexible non-electrically conductive membrane and an inelastic flexible dielectric member journalled in the membrane and extending from the first end of the membrane to the second end of the membrane. First and second coupling members are anchored to the ends of the dielectric member. The ends of the membrane are mated in sealed engagement with the coupling members so that the coupling members fluidically seal the ends of the membrane and fluidically seal 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.
