  • Publication number: 20150026984
    Abstract: The present invention relates to stripping devices by way of which a cable sheath can be removed from a cable end and in this way the cable core can be exposed. Such a stripping device for stripping a cable sheath from a cable comprises a first cutter half and a second cutter half which are movable towards one another in a first direction. The mutually facing lateral surfaces of the first and second cutter halves are spaced apart from one another at a spacing in a second direction substantially perpendicular to the first direction, and a voltage is applied to the first cutter half and the second cutter half. Furthermore, the stripping device has an evaluation unit connected to the first cutter half and the second cutter half, said evaluation unit being able to detect a current flow through the first cutter half and/or the second cutter half (10).
