Profile Wire Conductor and A Power Cable

A power cable having a profile wire conductor with a central longitudinal axis and including stranded individual profile wires arranged in concentric wire layers around the central longitudinal axis, the concentric wire layers including an inner wire layer of profile wires of a first type having a first radial cross sectional geometry, and an outermost wire layer of profile wires forming an outer surface of the profile wire conductor, at least one of the profile wires in the outermost wire layer being of a second type and having a second radial cross sectional geometry being different to the first radial cross sectional geometry, comprising a semiconductive layer arranged around the profile wire conductor forming an interface between the profile wire conductor and the semiconductive layer, the interface being at least partly defined by the indentation or protrusion in the outer surface of the profile wire conductor.

A method for producing at least a part of a power cable, the method comprising:

• providing a plurality of profile wires of at least a first type having a first radial cross sectional geometry and of a second type having a second radial cross sectional geometry being different to the first radial cross sectional geometry;
• stranding the plurality of profile wires in concentric wire layers around a central longitudinal axis to form a profile wire conductor having an inner wire layer of profile wires of the first type, and an outermost wire layer of profile wires forming an outer surface of the profile wire conductor in which at least one of the profile wires in the outermost wire layer is of the second type,
• wherein the profile wires of the second type form an indentation or protrusion in the outer surface of the profile wire conductor during the step of stranding the plurality of profile wires.
