Abstract: An electrical ground connector assembly for providing a fast, secure, moisture-resistant ground connection without using special tools. The electrical ground connector assembly includes a ground rod and a cap having an tapered rod chamber for receiving the ground rod. The cap also includes a slot for receiving a ground wire. The angle of the slot may vary, depending on the diameter of the ground wire. The cap may be cylindrical or rectangular in shape. In installation, the ground wire is inserted into the slot of the cap. The upper end of the ground rod is forced into the rod cavity of the cap by any suitable manner, such as hammering the cap down over the ground rod. As the upper end of the ground rod reaches the end of the rod cavity, a compression contact is made between the wire and said ground rod. Alternatively, the ground rod can first be driven into the ground, and then the ground wire and the cap can be assembled on the ground rod.
Abstract: The invention concerns a method of installing a telecommunication cable (3) on a supporting cable (1), particularly on a ground or phase cable of a high voltage overhead line, whereby the telecommunication cable (3) is laid along the supporting cable (1) and is attached thereto in undulating form with the help of attaching elements (5; 11; 13; 15). This arrangement makes it possible to make repairs in a simple way on the supporting cable (1) and the telecommunication cable (3).

Abstract: A mast clamp assembly including a strap, a drop wire clamp, and a hook. The ribbon-like strap forms a loop which engages a utility pole or mast. The drop wire clamp includes a clamp for clamping to the drop wire and a loop which engages the hook. The hook includes a back wall and first and second side walls. The loop of the drop wire is received in loop mounting slots in the side walls and engages a protrusion on each side wall. Each side wall also has a strap mounting opening having a triangular-shaped lower portion and a rectangular-shaped upper portion. The hook is mounted on the strap by inserting the strap, bottom edge first, through a slot in the back wall into the lower portion of the strap mounting openings and rotating the hook around the strap such that the upper edge of the strap rotates into the upper portion of the strap mounting opening and the strap engages the hook back wall.

Abstract: A support for busbars of a busbar system, which can be fixed in place on a fastening surface and which forms a receptacle which is adapted to a width and a thickness of the busbar. A later attachment to the pre-positioned busbar system is made possible due to correspondingly divided supports, if the support has two L-shaped receiving elements, whose legs, aligned parallel with the fastening surface, determine the width of the receptacle, and which have on front ends facing each other dovetailed strips and dovetailed grooves aligned with each other, which extend in a longitudinal direction of the busbar to be inserted into the receptacle. The legs of the receiving elements are oriented perpendicularly with respect to the fastening surface and determine the height of the receptacle. The facing sides of the two receiving elements have projecting support strips, which can be inserted into longitudinal grooves of the busbar, to be placed into the receptacle.
Abstract: A grooved tubular protective sheath (10) with a slot and a longitudinal flange. In particular, the flange (24) is provided on one edge (16) of the slot substantially at the bottom of the grooves (12) and positionable under the other slot edge (17). The grooves are closed at the edges (16, 17) of the slot by transverse walls (22). A method for manufacturing a grooved sheath includes extruding and molding an annular sheath with a longitudinal flat strip level with flute edge hollows, cutting the flat strip along one of its flute edges to form a tongue that is integral only with the other flute edge. The method further includes heating the sheath and cooling it, while passing it between cones or calenders to bring the flute edges together, whereby the tongue passes between the cut edge. A device for making a grooved sheath includes a molding machine with two series of symmetrical parallel shells.
Abstract: Adaptable, line vibration damping/sag adjustment devices are provided with hollow regions that facilitate drilling of larger holes in the devices so that the devices can hold and clamp lines having correspondingly large diameters.

Two rails extend upward from the housing and support a hanger rod therebetween that is slidable along the lengths of the rails. An amplifier or other device may be hung from the hanger rod for connection to the utility cables. An adjustable center support bar extends across the upper aperture in the housing to provide support to the amplifier or other device hanging from the rail. A rock-like cover is configure to fit over and conceal the housing and be removably secured to the housing so as to provide an aesthetic look to the utility enclosure.

Abstract: A backplane stiffener mounts in a channel defined between parallel rows of connectors on a backplane. In a first embodiment, the stiffener has a substantially U-shaped cross section and has a maximum width less than the width of the channel. The sidewalls are parallel and linear throughout the length of the stiffener. A second embodiment is adapted for use in "dog-legged" connector channels wherein at least one of the connectors in the row is wider than or spatially offset from the remaining connectors. The stiffener is preferably formed from a sheet of pliable material, for example sheet metal which is manipulated to form various features and folded longitudinally to form a rigid member. Rigidity is enhanced in an economic manner which does not interfere with backplane operations.

Abstract: An insulating cap for a loadbreak bushing includes an outer conductive jacket preferably having a ground wire receiving member thereon. The ground wire receiving member may be in the form of an integral tab having a bore therethrough for connection of the ground wire. The insulating cap further includes an insulation member positioned in adjacent relationship to the inner surface of the conductive jacket. In a preferred embodiment, both the inner surface of the conductive jacket and the inner exterior surface of the insulation member includes a smooth, dome-shaped region which helps to control electrical stresses, if any. The inner surface of the insulation member defines a bushing receiving space which substantially corresponds to the exterior shape of a loadbreak bushing. When properly grounded, the outer conductive jacket of the insulating cap is maintained at ground potential.
Abstract: A device for attaching busbars of square or rectangular cross section on a support rail using electrically non-conducting support elements, which can be connected with the support rail and form a busbar receptacle adapted to the cross section of the busbar. With a simple fastener, assembly is considerably simplified because two post-shaped supports per busbar can be attached as support elements on the support rail, wherein spacing between the supports is matched to the width of the busbar and a height is matched to the thickness of the busbar. A base plate is arranged between the two supports, which insulates the busbar receptacle against the support rail and which is captively held between the holders. The ends of the supports facing away from the support rail can be closed by a strip.
