ABSTRACT:
A covered distribution wire is provided with a clamp device having sufficient mass to provide conductor protection against damage from fault current arcs over a section of the conductor where the insulation cover is removed for interconnection or insulator support purposes. The clamp comprises two members which are bolted together to surround the conductor section such that an enlarged disc-like end clamp portion is positioned about the conductor within one and a half centimeters of an end face of the adjacent wire cover. The two members are secured together such that a pair of slots exists between them along opposite sides of the conductor section with splatter barriers located on one end thereof. The slots are tapered with increasing width in the radially outward direction with the minimum width being great enough to avoid weldment and the maximum width being less than that which allows fault arc travel through the slot to the conductor section. The clamp mass is at least a minimum value needed for practicality in usage and otherwise is based on the fault energy to be absorbed from fault arcs in the expected usage.
