More particularly, the invention includes a body having an opening through which the cable passes and into which a wedge is driven to captivate the cable. The body further includes attachment points for being attached to a high tension tower or utility pole.

Abstract: A support for electric cables, in instances where the configuration of the distribution system is not fixed, comprises a pair of cable-clamping members whose outer surfaces form wedges guided by a pair of converging flanges. The inner surfaces of these members clamp the point or region of a cable that is to be held fixed in space. A pair of outer clamping members surround the above flanges. Coupling formations ensure that all parts of the structure always stay in their proper relative positions, allowing but a widening or a narrowing of the cable-receiving cavity. The flanges have projections or abutments which enter into lateral elongated recesses of the cable-clamping members and thus limit the possible minimum and maximum spacing of the latter, which depends upon the size of the electric cable that is to be supported.

Abstract: A cable clamp embodies a body having a cable receiving groove therein and a keeper mounted for movement to selected positions over the cable receiving groove. A resilient member between the body and the keeper urges the keeper to a position which permits a cable to be inserted or removed. Clamping members are carried by the body in parallel relation to the groove, with one clamping member being connected to the body in a manner which permits it to be tilted and moved selectively to a released position and a connected position relative to side portions of the keeper adjacent thereto.

Abstract: A conductor support member includes an external surface having a first portion thereon. The first portion is shaped to generate a localized increase in voltage gradient. Shielding means including surfaces intersecting to define a sharp edge are provided to promote a negative corona discharge adjacent the first portion. The said negative corona discharge produces a positive space charge to reduce the voltage gradient at the first portion. This inhibits the generation of positive corona discharge.

Abstract: An improvement in a flat type cable suspension structure which comprises a support structure comprising an upper support member and a lower support member vertically spaced from the upper support member and fixedly secured with respect to the ground, and a flat type jacketed cable extending crosswise with the support structure. The flat type cable extends downwardly through the spacing between the upper and lower support members toward said lower support member in such a manner that one face of the cable has a portion abutting against the rear side of the upper support member and the other face of the cable has a portion abutting against the front side of said lower support member. An exposed extension stemming outwardly from a tension member buried in the jacket of the cable is securely hooked over and held in a tightly suspended state on a hanger member provided on the front side of the upper support member.

Abstract: A V-suspension insulator assembly for suspending multiple conductors is disclosed, in which an angle of intersection of axial lines of connecting hardwares for connecting an inverted-U shape upper yoke to which V-suspension insulator strings for suspending multiple conductors are attached and a lower yoke which extends between opposite legs of the upper yoke is selected to be equal to or larger than an angle of intersection of axial lines of the insulator strings; and the intersecting point of the axial lines of the connecting hardwares is positioned near a center of gravity of a polygon defined by connecting points at which suspension clamps are attached to the lower yoke. With this construction, the movement and rotation of the lower yoke by load by wind pressure in a direction transverse to the conductors can be prevented and a space between the conductors can be reduced while preventing the mutual contact of the conductors and the twist of the conductor bundle.

A secondary filter removes fine mist and powdered coatings from the overspray. One section of the duct system is preferably made from disposable materials and a removable liner is preferably used in a collecting receptacle to facilitate clean up operations after the coating is completed.

Abstract: A suspension bracket and apparatus for a bundle conductor has a yoke plate suspended at opposite sides thereof by respective insulator strings. To reduce high voltage gradients across the lowermost insulators of the strings, one or more of the sub-conductors is clamped to the upper side of the yoke plate between the strings. To facilitate "clipping in" of this sub-conductor by providing a temporary suspension connection between one of the strings and the yoke plate in order to allow that string to be uncoupled and thereby to allow the sub-conductor to be raised past the uncoupled string, the yoke plate is provided with a cylindrical opening extending transversely of the axis of that string by which the temporary connector can be connected to the yoke plate.

Abstract: A clamping holder for busbars includes a base member having at least one projection, opening and clamping surface all located and shaped for reversible positioning of a pair of the base members with the projection on each received in the opening in the other, and with the clamping surfaces in spaced-apart facing relationship to define a part receiving aperture in which a busbar or other part is clamped and held.

Abstract: A suspension clamp for an overhead electrical cable includes a clamping member which clamps the cable along a portion of its longitudinal sides. Arms extend outwardly from the opposed lateral sides of the clamping member along the direction defined by the cable. Supporting members for the cable are mounted on each of these arms at a distance from the clamping member such that the cable will be free to oscillate within the space between the clamping member and each of the supporting members.

Abstract: A cable-retaining device attached by hooking to a support mounted on a pole comprises a suspension body and a guiding member rotatably mounted within the body and associated with a suspension hook. A passageway formed in the guiding member is located in the line of extension of two outer passageways formed in the suspension body in a cable-displacement position and is angularly displaced with respect to the body passageways in a cable-retaining position.
