A method and armoured cable for transporting an alternate current at a maximum allowable working conductor temperature, as determined by the overall cable losses, the overall cable losses including conductor losses and armour losses. The cable includes at least one core, including an electric conductor having a cross section area, and an armour surrounding the core along a circumference. The method includes: causing the armour losses not higher than 40% of the overall cable losses by having the armour made with a layer of a plurality of metal wires having an elongated cross section with a major axis, the major axis being oriented tangentially with respect to the circumference; and transporting the alternate current at the maximum allowable working conductor temperature, in the electric conductor having cross section area sized on the overall cable losses including the armour losses not higher than 40% of the overall cable losses. |
