ABSTRACT:
An insulated distribution conductor separated from the substation by one or more fuses is protected from arc damage by a clamp device having sufficient mass to absorb the arc energy and thereby prevent burndown and diameter reduction of the conductor at a point where the insulation covering has been removed. The clamp comprises two members which are bolted together to surround the bare section of the conductor and provide additional heat-absorbing mass at the point where the arc tends to dwell, i.e. at the end face of the insulation covering farthest from the power source.
