A power cable () includes an outer sheath (), at least one conductor element () arranged within the outer sheath and one or more filler elements () arranged within the outer sheath. At least one of the filler elements is hollow such that a cooling fluid can be passed through the filler element.

Internal cooling of power cables and power umbilicals

A pipe for underwater transportation of fluid is indicated which includes a pressure-tight metal inner pipe for conducting the fluid, wherein for its stabilization in radial direction at least one profiled metal strand and for stabilizing in the axial direction at least one tension-proof strand are wound around the inner pipe. The inner pipe () is a metal pipe which is corrugated transversely of its longitudinal direction and which for stabilization in the radial direction is surrounded by at least one first radial reinforcement () which is composed of a profiled helically extending profile strip whose windings are placed closely next to each other or engage each other and are hooked together. Arranged around the first radial reinforcement () is arranged a metal pipe corrugated transversely of its longitudinal direction as the outer pipe (); at least two layers of tension-proof strands () are wound around the outer pipe (), preferably with oppositely directed pitch.
