BUSBAR CLAMPING SYSTEMS

摘要

Busbar clamping systems and electric power busway systems for distributing electricity are disclosed herein. An aspect of this disclosure is directed to electrical busway systems with improved means for minimizing or eliminating gaps between the busbars, the surge clamps, and the duct housing. In one embodiment, the busway system includes a plurality of electrically conductive busbars. The busbars are stacked one on top of the other to create a busbar stack. The busway system also includes a first duct side in opposing spaced relation to a second duct side. The stack of busbars is disposed between the first and second duct sides. One or more cam fasteners operatively engage the stack top and/or stack bottom. The cam fasteners are configured to apply a selectively variable compressive force to the stack of busbars.
