Claim 0:
1. A deep sea cable comprising:
a cable core surrounded by armouring,
wherein the armouring is surrounded by an outer jacket,
wherein the cable core comprises at least one power cable, the cable core having a core jacket, and the core jacket surrounds the power cable, where the power cable comprises a conductor, surrounded by a conductor insulation, said power cable having a central conductor core of a polymer material selected from the group consisting of polypropylene, polyethylene, polyolefin, thermoplastic polyester or rubber, with the central conductor core is less stiff than the conductor,
wherein the armouring comprises synthetic stiff ropes arranged in at least two helical layers around the cable core, and interstices between the stiff ropes of at least two helical layers are filled with a high viscous filler with an apparent viscosity of more than 500 Pas at 35° C., measured according to ASTM D3236,
wherein, within said cable core, interstices in the cable core, inside the core jacket, have the same high viscous filler as the armouring interstices between the core jacket and the outer jacket,
wherein said high viscous filler and said stiff ropes together are sufficient to prevent radial deformation and allowing movement of individual ropes during bending under tension.
