ABSTRACT:
An insulating assembly for an overhead power line has a main subassembly formed of two parallel spaced insulators joined at their ends by aluminum end pieces. The end pieces each have a slot aligned with the space between the two insulators and a rod projecting from the end piece in alignment with the slot but below the slot. This arrangement enables the subassembly to be hung on a hot power line with the line passing along the slots and the space between the insulators. The rods may be clamped to the line by any suitable device such as wedges and C-shaped clamps. With the subassembly thus mechanically and electrically connected securely to the line, the line can be severed at a location between the end pieces and the free ends forced apart.
