Abstract: 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.

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 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.

Abstract: A set of components for assembling a temporary wire suspender includes in the set a yoke plate, a plurality of J-hook assemblies, a plurality of linkage members, and a plurality of removable couplers configurable to handle an expandable number of energized or de-energized conductors or sub-conductors. Positive control of the suspended and/or supported energized or de-energized conductors or sub-conductors is achieved by using releasable latches on the J-hook assemblies.

Abstract: 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.

Elongate rigid, electrically conductive rollers are rotatably mounted to each of the stub arms and the beam so as to form an electrically conductive rolling surface extending around the interior of the U-shaped frame for rotationally supporting sagging electrical conductors thereon.
