Patent ID: 8723030

Claim:
A power umbilical, a DEH power cable or general umbilical, including a plurality of high power cables for transfer of large amounts of electric energy, filler material in the form of stiff elongate plastic elements located at least partially around and between the high power cables and which together are collectively gathered in a spiralled bundle by means of a laying and closing operation, and a protective sheath that encapsulates the high power cables and the filler material, wherein the high power cables, at intervals in the longitudinal direction of the cables, are provided with frictional means which cooperate with the filler material for frictional engagement with and load and weight transfer to each other, while the high power cables between said vulcanisation spots extend freely in longitudinal cavities within the filler material for possible expansion and contraction of every single high power cable during alternating temperatures within the conductor of the high power cable.
