Abstract
Submarine electrical cable system (100) having a substantially circular cross-section and comprising: a first insulated core (1) and a second insulated core (2); a three-phase cable (3) comprising three stranded insulated cores (8) the three-phase cable (3) being stranded with the first core (1) and the second core (2); an armor (4) surrounding the first core (1), the second core (2) and the three-phase cable (3).
Claims21
A submarine electrical cable system having a substantially circular cross-section and comprising:
- a first insulated core and a second insulated core each suitable for DC transmission;
- a three-phase cable comprising three stranded insulated cores suitable for at least AC transmission, the three-phase cable being stranded with the first insulated core and the second insulated core;
- and
- an armour surrounding the first insulated core, the second insulated core, and the three-phase cable,
- wherein the submarine electrical cable system is free of insulated cores suitable for DC transmission other than said first and second insulated cores and free of three-phase cables suitable for at least AC transmission other than said three-phase cable comprising the three stranded insulated cores.
