Submarine power cable

A submarine power cable comprising:

• a plurality of stranded conductors, each stranded conductor being formed of a plurality of metallic wires;
• and
• an insulation system surrounding each stranded conductor,
• wherein each stranded conductor, at given intervals of the submarine power cable, is compressed to a substantially solid configuration across an area to form a plurality of watertight partitions along a length of the submarine power cable,
• wherein each said insulation system comprises an inner semiconducting layer, a solid insulation layer and an outer semiconductor layer,
• wherein at least one stranded conductor of said plurality of stranded conductors within said submarine power cable is without filling compound in between voids or spaces of the metallic wires forming a clean stranded conductor, and
• wherein each stranded conductor has a thin sleeve or casing over the area that is compressed, such that where each stranded conductor is compressed to the substantially solid configuration, the thin sleeve or casing is level with, or in line with, area of each stranded conductor which is not compressed, thereby providing each stranded conductor with a substantially equal diameter over the length of each stranded conductor.
