Electric power cable, an off-shore installation provided therewith, and use thereof

摘要

An electric power cable including at least one electric conductor. An electric insulation surround the conductor and includes a polymer. A tubular protective sheath surrounds the electric insulation and acts as a water barrier that prevents water intrusion into the electric insulation. The protective sheath includes a metal as a main constituent. The cable includes at least one density-raising element of a material of higher density than the material of the protective sheath, in order to increase the density of the cable such that too large motions thereof are prevented when the latter is installed in open sea.

1. An electric power cable, comprising:
at least one electric conductor, an electric insulation surrounding said conductor and comprising a polymer, a tubular protective sheath surrounding said electric insulation without unsealed seams and acting as a water barrier that prevents water intrusion into the electric insulation, wherein said protective sheath comprises a metal as a main constituent, wherein said protective sheath comprises copper or steel as main constituent, and at least one density-raising element of a material of higher density than the material of the protective sheath, in order to increase the density of said cable such that too large motions thereof are prevented when the latter is installed in open sea, wherein said at least one density-raising element comprises lead as a main constituent, wherein said at least one density-raising element comprises a rod extending in the longitudinal direction of the cable.
