摘要: A temporary insulated conductor guard structure is mountable on an electrical insulator. The electrical insulator is mounted on the distal end of a crane or truck boom. The conductor guard structure includes a U-shaped frame having a horizontal elongate beam and a pair of stub arms upwardly extending from opposite ends of the beam. 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.

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: 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.

摘要: A method and apparatus for calculating line sag in a span of a conductor is provided. The method includes using a portable smart device having one or more accelerometers and running a line sag application on the processing device. The line sag application enables acceleration data of return waves generated on the conductor to be collected using the smart device and to be plotted as a function of time for display on the smart device. The method further includes placement of time markers on the plotted data displayed on the smart device to determine elapsed time and calculating line sag using the elapsed time.

摘要: A system for lifting a sub-conductor bundle having a plurality of spaced-apart sub-conductors comprises a single point lifter base and an accessory mounted onto a free end of a support. The support is electrically insulated and comprises one or two tiers of elongate insulators extending away from the base. The base is for mounting the support onto a distal end of a boom. The accessory has at least one wire cage mounted on a cart, the cart mounted on an arcuate track and adapted for free translation along the inner side of the track between first and second ends of the track. The wire cage is in a first orientation when the cart is positioned at the first end of the track, and in a second orientation when the cart is positioned at the second end of the track, the first and second orientations perpendicular to one another.

摘要: A bundle lifter for lifting a sub-conductor bundle having a plurality of spaced-apart sub-conductors, includes a base platform adapted for rotational mounting onto a single point conductor lifter, four sub-conductor wire cages mounted on the platform to support a sub-conductor thereon, each wire cage adapted to releasably hold a single sub-conductor and to swivel relative to the platform, wherein when the wire cages are positioned under the sub-conductor bundle, the wire cages are swivelled to align their corresponding rollers with a corresponding sub-conductor for rolling support of the sub-conductor on the roller as the bundle lifter is elevated on the support upwards from under the sub-conductor bundle to simultaneously pick each sub-conductor in the bundle into its wire cage for translation of the bundle from an original position to a new position spaced apart from the original position.

摘要: A method and apparatus to invert a robotic arm, includes an angling adaptor and swing arm. The angling adaptor includes a truck or crane boom head adaptor and a hinge coupler. The swing arm extends downwardly from the angling adaptor and may include a boom adaptor arm and a jib. The lower end of the swing arm is mounted to the main beam of the robotic arm. The hinge coupler mounts to the upper end of the crane or truck boom. The robotic arm is mounted on the swing arm so as to downwardly orient the insulators on the robotic arm. A lowermost end of each insulator is adapted for releasably holding an electrical bypass which may include a bus bar and electrical cable jumpers.
