Power cable for movable loads

摘要

Wires with three insulated electric conductors have each conductor (15) encased by an inner conductive layer (16), an insulation (17) lying over it and an outer conductive layer (18) fitted over it. There is also an earth conductor. Each wire has an electric shield (S) applied over the outer conductive layer. A unit made from wires and an earth conductor forms a common sleeve made from insulating material.
