1. A power cable, or power umbilical, comprising:
a number of electric cables for transfer of large quantities of electric power/energy; filler material in the form of stiff elongate polymer elements located at least partially around and between the number of electric cables, the number of electric cables and stiff elongate polymer elements being gathered in a twisted bundle by means of a laying operation; a protective sheath that encompasses the electric cables and the filler material; and at least one load carrying element at a predetermined location in the cross section of the power cable/umbilical, the number of electric cables, the stiff elongate polymer elements and the at least one load carrying element, are either laid in a continuous helix, or alternately laid, i.e. by continuously alternating direction, in the entire or part of the longitudinal extension of the power cable/umbilical, to form a bundle, and wherein each stiff elongate polymer filler element is manufactured of said polymer material, which polymer material has been added at least one constituent that transforms the filler material to be substantially more heat conducting and heat dissipating. |
