Abstract

Armoured power cable (10) for transporting an alternate current comprising at least one core (12), comprising an electric conductor (12a), and an armour (16), surrounding the at least one core (12), comprising a plurality of armour wires (16a) having a ferromagnetic inner portion (162) and an electrically conductive cladding (164). The cladding of electrically conductive non-ferromagnetic cladding having an electrical conductivity greater than that of the stainless steel onto a ferromagnetic armour wire overcomes issues relating to hysteresis and eddy current losses in the cable armour while maintaining the mechanical resistance and limiting the increase of the cable manufacturing cost.
