<p>11PCO-4530 INSULATING SUPPORT STRUCTURE FOR AN ELECTRIC BUS CONDUCTOR A bus conductor with a cylindrical external surface is supported on an insulator by first and second bussupporting members, each comprising spaced legs and flanges at the free ends of the legs. The bus-supporting members embrace the bus conductor when the flanges are in juxtaposition. One set of flanges are fastened together by fastening means comprising a screw extending between the flanges and threaded into one of the flanges and a nut positioned between the flanges and threaded onto the screw. The nut is axially movable on the screw first and second positions. When in the first position, the nut is tightened on the screw against the juxtaposed flanges of one of the bus-supporting members, thereby locking the flanges in a fixed-joint position. When in the second position, the nit is tightened on the screw against the juxtaposed flange of the other bus-supporting member, thereby locking the flanges in a slip-joint position. The bus conductor can slide with respect to the supporting members when the flanges are in said slip-joint position.</p> |
