  • Patent number: 6311600
    Abstract: An electric power cable sheath cutter for longitudinally slicing an outer metallic sheath of a power cable include a frame arranged to be clamped by clamps to each end of a selected longitudinal section of the power cable. A carriage, slidingly mounted to the frame, has rollers that embrace an outer surface of the power cable so that the carriage “floats” on the cable in use. A milling tool with its drive motor is supported on the carriage and is adjustable up and down to enable a depth to be chosen. As a result, the sheath is cut through and inner strands of the power cable are not damaged. The effective depth of the remote end of the cutting tool is controlled by operation of a first motor 20, and the carriage is driven along in use the frame by a second motor so that the cutter can operate automatically without close manual supervision.
