Abstract

A power cable (10) comprises at least one cable core (11) comprising an electrical conductor (20) having two or more conductor elements (12) and an insulating system (19, 15, 16) radially surrounding the electrical conductor (20), where the insulating system comprises an inner semiconductive layer, insulation layer and outer semiconductive layer. The electrical conductor (20) comprises a plurality of transversally arranged watertight barriers (21) arranged intermittently along the longitudinal direction of the power cable (10) wherein the plurality of watertight barriers (21) have a diameter (D) and a length (L), where the diameter of the watertight barriers essentially corresponds to the diameter (d) of the conductor, and wherein the outer surface of the plurality of watertight barriers (21) is watertight linked to an extension layer extending a distance along the length of the electrical conductor. A method for manufacturing a power cable with water barrier, comprising the steps of: a) providing an electrical conductor (20) having two or more conductor elements (12), b) providing a plurality of watertight barriers arranged intermittently along the longitudinal direction of the electrical conductor, wherein the plurality of watertight barriers have a diameter and a length, where the diameter of the watertight barriers essentially corresponds to the diameter of the electrical conductor, c) link the outer surface of the plurality of watertight barriers (21) watertight to an extension layer so that the extension layer extends a distance along the length of the electrical conductor, and d) providing an insulating system (13, 15, 16) radially surrounding the electrical conductor (20), where the insulating system comprises an inner semiconductive layer, insulation layer and outer semiconductive layer.
