A cover system for covering an electrical connection between first and second electrical cables each having a primary conductor and a neutral conductor, includes a neutral connector and a neutral connector cover. The neutral connector is configured to mechanically and electrically connect the neutral conductors of the first and second electrical cables. The neutral connector cover has a cavity. The neutral connection cover is configured to receive the neutral connector in the cavity to protect the neutral connector.

There is provided a connecting structure for electric cables. A first electric cable includes a first core and a first cover covering the first core. A portion of the first core is exposed from an end of the first cover. A second electric cable includes a second core made of a different metal from that of the first core and a second cover covering the second core. A portion of the second core is exposed from an end of the second cover. A tube is shrunk in a state where the tube accommodates thereinside the portion of the first core and the portion of the second core which are connected to each other. An inside of the tube except for the portion of the first core and the portion of the second core is filled with cured hot-melt.

A heat-recoverable component includes a tube-shaped or cap-shaped base material layer having heat shrinkability, and an adhesive layer formed on an inner circumferential surface of the base material layer. The adhesive layer includes a low-viscosity adhesive portion and a high-viscosity adhesive portion disposed between the low-viscosity adhesive portion and an opening of the base material layer. The low-viscosity adhesive portion has a shear viscosity of 10 Pa.Math.s or less at a shear rate of 1 s.sup.1 at a heat shrinkage temperature of the base material layer. The high-viscosity adhesive portion has a shear viscosity of 100 Pa.Math.s or more at a shear rate of 1 s.sup.1 at the heat shrinkage temperature of the base material layer. At the heat shrinkage temperature, a ratio of the shear viscosity of the high-viscosity adhesive portion to the shear viscosity of the low-viscosity adhesive portion is 15,000 or less.

A method for electrically grounding structures or equipment includes providing an open-topped enclosure having peripheral sidewalls defining an interior cavity, positioning the enclosure over an in situ soil mass, placing a selected soil material in the cavity, and installing a grounding device in the soil contained in the cavity, so as to establish electrically-conductive continuity between the grounding device and the soil material in the cavity, and between the soil material in the cavity and the underlying in situ soil mass. Electrical cables can then be run between the grounding device and a structure or equipment to effect electrical grounding thereof. The effectiveness of the resultant electrical grounding may be enhanced by moistening the soil material in the enclosure and/or the in situ soil mass. The enclosure may have an open bottom, or may have a floor element with apertures allowing passage of moisture.

An electrical connection device including a support and an electrically conductive terminal lug, wherein the support includes a first face, with channels projecting from a second face opposite from the first face and defining between them a housing; the terminal lug includes a base for placing in the housing and a shank fastened coaxially to the base, the base including a first face from which the shank extends and a second face opposite from the first face for coming to bear against the second face of the support; the terminal lug including a locking ring having the shank passing through its center and movable in rotation relative to the shank, the ring including ramps extending from the outer periphery of the ring, the ramps co-operating with the channels.

A dry power cable termination has an insulation sleeve, a silicone rubber tube and a stress control cone. The insulation sleeve has an inlet and an outlet. The silicone rubber tube is disposed over an exterior of the insulation sleeve; and the stress control cone is received within the insulation sleeve. Additionally, the dry power cable termination has a shielding sleeve, an electrode, an-electric connection assembly and a clamping pipe. The shielding sleeve is received within the insulation sleeve and fitted over an exposed segment of an insulation layer of the power cable. The electrode is received within the insulation sleeve and is electrically connected to a first end of the shielding sleeve. The electric connection assembly is received within the insulation sleeve and electrically connects a second end of the shielding sleeve opposite to the first to an exposed segment of a conductor core of the-power cable.

The invention relates to a method of connecting electrical wires, conductors, or connections together by rotating the connector ends in an enclosure to tightly twist the wire ends together and also includes a clamping mechanism to prevent the wires from untwisting, becoming loose, or falling out of the enclosure. The present invention increases the holding ability of current rotating tools for electrical wires and connections.

The invention relates to the field of thermonuclear fusion and can be used in devices for electrically connecting internal elements of the reactor chamber to the vacuum vessel of the nuclear fusion reactor. The present device for electrically connecting elements inside the chamber of a reactor to the vacuum vessel of the nuclear fusion reactor comprises lamellar electrically conductive elements with surface portions oriented in different directions, said elements being stacked between flanges. The device is made as an integral unit, where profiled slots are formed with connecting walls therebetween. The connecting walls constitute the electrically conductive elements and have profiled sections of an increased thickness between the differently oriented surface portions at transition areas to the flanges provided at the end parts of the integral unit. The technical effect of the present invention is an increase in the cyclic strength of the electrically conductive elements at the transition areas between the elements and the flanges and between the differently oriented surface portions (at bends) of the elements. The invention also provides that the electrically conductive elements have similar technical characteristics.

Power outlets adapted for installation within an enclosure are provided. Power outlets are provided having a safety interlock adapted to prevent the creation of a hazardous condition within the enclosure as a result of the continued operation of an electrical device within the enclosed space. The safety interlock may include current limiting circuitry and hardware, hazard sensing devices interconnected with such current limiting circuitry and hardware or other circuit breaker switches, and combinations of such safety interlocks. The power outlets may also be adapted for installation within a movable enclosure, such as, for example, a drawer.

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