A multi-phase submarine power cable including: a plurality of power cores arranged in a stranded configuration, and a curvature sensor including: an elastic elongated member, and a plurality of Fibre Bragg Grating, FBG, fibres, each FBG fibre extending axially along the elongated member at a radial distance from the centre of the elongated member; wherein the elongated member extends between the stranded power cores along a central axis of the multi-phase submarine power cable.

A cable core for a cable, in particular, for an induction cable that includes multiple such cable cores which have a conductor that is interrupted in the longitudinal direction at specified longitudinal positions at multiple separation points, thereby forming two conductor ends. An insulating intermediate piece is provided for connecting the conductor ends, and the conductor ends are arranged on both sides of the intermediate piece. The conductor and the intermediate piece are surrounded together by a continuous insulating jacket in order to form the cable core. In a preferred concept, a respective intermediate piece is arranged between the two conductor ends by two adapter elements. In another preferred concept, a respective intermediate piece, in particular, a ceramic intermediate piece, is connected directly to two conductor ends. A cable is formed from a plurality of such cable cores.

A composite cable includes an electric wire bundle, and an outer layer sheath covering the electric wire bundle. The electric wire bundle includes a one-core first electric wire, a one-core second electric wire, a two-core twisted pair electric wire, a one-core third electric wire, and one wire-like interposed material formed in the shape of a wire using a polymer. In the electric wire bundle, in a cross sectional view the twisted pair electric wire is disposed on one side of a centerline joining the center of the first electric wire and the center of the second electric wire, and the third electric wire and the wire-like interposed material are disposed on the other side of the centerline.
