Longitudinally watertight cable with plastic insulation and an outer spiral or annular corrugated metal sheath

摘要

The invention relates to a longitudinally watertight cable having plastic insulation and an outer spiral or annular corrugated metal sheath, having a core or a core assembly with plastic insulation and having an outer conductive layer and a sealing layer which is arranged between said conductive layer and the metal sheath, and achieves the object of providing such a cable with a moisture trap which makes it possible to seal the cable effectively in a short time even against advancing water penetration. This object is achieved in that the sealing layer (5) can expand and a sealing strip (6), which runs along the cable axis and fills the corrugation peaks (9) of the metal sheath (7) in this region, is arranged between said sealing layer (5) and the metal sheath (7) in an angular region of the circumference of the sealing layer (5) which can be predetermined (Fig. 1). <IMAGE>
