  • Arc protection arrangement for covered overhead power distribution lines
    Patent number: 4398057
    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 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.
