An elongated waterproof enclosure for spliced telephone cables is provided by a two-part molded resinous housing that provides openings for one or more cables at opposite ends. A one piece resilient sealing gasket includes longitudinally slitted tubular gaskets at the ends to snugly receive individual cables side by side. The grommets at each end are formed integrally and connected by flat connecting pieces arranged to be transverse to opposed narrow edges of the mating opposed housing portions. The narrow edges when clamped together pinch and seal the flat pieces. Housing ends conforming to the grommets also have opposed narrow edges which, when clamped together, pinch the grommets and provide a seal. The housing pieces are preferably connected along one side by an integral molded hinge offset from the opposed longitudinal edges to give the seal clearance. At the opposite side of the housing, offset from the edges, are rigid flanges molded integrally with the housing parts. The flanges lie generally parallel to one another when the housing is closed. Urged together by suitable clamping device, the flanges apply pressure to urge the opposed narrow edges together and into the gasket. A preferred clamping device is a channel-like member having cam elements on the opposed inside walls of the channel cooperating with cam elements on the flanges. A tubular port is provided through one of the housing parts and preferably provided with a closure which is piston-like and seals against the sidewalls of the cylindrical tubular port. Structure to draw the piston into the housing is connected between the piston and the housing. As the piston is drawn into the port against the insulating fluid filling the housing parts, the piston imposes pressure on the fluid to fill small spaces within the housing. A thinner part of the housing wall provides a pressure gauge designed to be forced outwardly as a protruding bubble when the pressure is sufficient to fill the voids as desired.

A power line de-icing apparatus which is installed onto a power line without the need for disconnecting the power line. A temperature sensor and an ice sensor on the apparatus automatically activate the de-icing mode of operation. An internal motor and drive wheel move the apparatus along the power line in both directions, one direction at a time. Heaters and chisels on the apparatus remove any ice on the power line in one direction at a time. Power for the apparatus is generated from the electrical power carried by the power line using transformers. Proximity sensors on the apparatus detect stopping devices placed on the power line to stop the motion of the apparatus.

An insulator bushing wildlife guard having features for easier alignment and installation of the guard on the bushing. The guard has two hinged body sections of insulating material. An outer edge of each body section is provided with a plurality of flexible fingers that allow conductors to pass through from the interior to the exterior of the enclosure when the two portions of the guard are engaged. In one embodiment, the guard is spring biased toward a closed position. A handle on the back has inner grooves to make it easier to grasp and manipulate the guard using a shotgun stick. On a lower front side of each portion of the guard, spaced-apart, curved, horizontal upper and lower flanges help align the guard with the topmost skirt of a bushing. Medial walls having a curved, sloped, concave or otherwise inwardly-directed configuration between the two flanges facilitate forcing the guard open by pushing it against the bushing. An external tab limiter, disposed above the upper flange, makes it difficult to install the guard over any part of the bushing other than the topmost skirt of the bushing. An alternative version of the guard has a releasable trigger, which is used to hold the two portions in an open position until the bushing or power line displaces the trigger and allows the biasing spring to close the two cover portions. The guard is provided with a handle for grasping by a manipulator tool. In one embodiment the handle is provided with inner grooves for grasping by a shotgun stick. In another embodiment, an adapter releasably engages the handle and provides means for attachment to a hotstick.

A system and method, and robotic equipment for mechanical and / or electrical bypassing of short sections of energized high voltage line conductors by gripping the conductor at two close-by points, making good electrical and mechanical connection, then drawing the two points towards one another so as to relieve both mechanical and current-carrying duty of the bypassed conductor section. Doing so can provide slack on the bypassed conductor section for maintenance or repair while simultaneously providing an alternative path for electric current, or increase tension on the adjacent conductor sections by essentially shortening the conductor in the region where the invention is applied. The invention may then reverse direction, placing (stretch) tension on the bypassed conductor section and the point of repair to assure its mechanical integrity. Mechanical bypassing only to temporarily shorten specific conductor spans may be achieved by the same device. Electrical bypassing only may be achieved in a similar manner by gripping and bridging two separate high voltage conductors, thus providing a means to connect and / or disconnect them with the aid of switching equipment incorporated into the invention. The invention allows all of the foregoing to be accomplished at line potential and in close line proximity by virtue of its being mounted on an insulated boom or suspended from a hovering helicopter or suspended from the line itself.

Method and apparatus for protecting wildlife from contact with an energized fuse assembly known as a “cutout”, also known as a “disconnect”. The cutout is shrouded from above and three sides. One side is left open to facilitate installation or removal of a fuse holder assembly. The shroud is formed to allow the use of a hot-stick for installation and removal of a fuse holder assembly into a fuse receptacle formed by upper and lower contact assemblies held in opposition to each other by an insulator. The shroud provides a slot enabling installation when a wire is connected to the upper contact assembly. A pin is used to hold the shrouding in place.

An electrical transmission line is provided which employs the conductive and structural material usually formed into current carrying cables to form the tubes of a pressurized pipeline which is then suspended from insulators on tall poles to create a low impedance electrical conductor and a high volume gas pipeline. The poles of wind generator towers may be employed to support the conductors and to store the gas from the pipeline. Auxiliary electrical generation may be added at the towers to assist in voltage or VAR support at times of peak load. Electrolysers may also be employed to increase electrical power consumption during offpeak times and supply the fuel gas or compressed air generated into the pipeline for sale or into storage for later re-conversion back into electricity at times of peak demand. A novel line layout plan is provided which reduces the cost of the transmission line.
