Abstract: A bracket for supporting electrical components that accommodate the transmission of three-phase electrical energy. The bracket includes a crossarm, generally of linear design, and formed of electrically conductive tubular material for allowing its supplemental use as a bus bar for grounding of the various electrical components mounted thereon. A series of angle members having flanges that are arranged either horizontally or vertically disposed with respect to a surface of the crossarm, form mounting surfaces upon which either terminations, cutouts, or arrestors, or any combination of such, may be mounted all upon one level with respect to a utility pole. The supports that mount the crossarm to the utility pole are preferably electrically insulative, so as to enhance the protection of a lineman working in proximity to the crossarm.

Abstract: In a collapsible junction support bracket, a series of frameworks, vertically disposed, are pivotally mounted to each other through the agency of a series of side stringers, and braces also connect laterally of the bracket for holding it erect, as when assembled, but said braces are removable to provide for collapsing of the bracket to facilitate its shipment.
