Abstract

The cable comprises an electrically conducting core (2) arranged to be in contact with an inner, first semiconducting layer (4) surrounding the core. A first insulating layer (6) surrounds the first semiconducting layer, and an outer second semiconducting layer (8) surrounds the first insulating layer. A second insulating layer (10), wound around the outer semiconductor layer, and an earthed conductor (12), applied as a band divided into separated parts, arranged onto the insulating tape, are provided to earth the cable for alternating voltage and/or impulse voltage continually along at least a large part of its length. Preferably, the tape is wound in separated turns with a space provided between each turn and/or openings (24) are provided in the tape so that air filled spaces are formed between the second semiconductor layer and the casing of the earthed conductor, which spaces form discharge gaps in order to divert voltage impulses from the second semiconducting layer, if their voltage exceeds a predetermined limit.
