In order to reduce the AC losses in a superconducting conductor element (31) subjected to an external magnetic field and through which a current flows, it is proposed to wind the tapes (17) comprising superconducting material of each layer (14, 15) at such a mutual distance (D) that the gap between the superconducting material of adjacent tapes is not smaller than a predetermined minimum value. The invention applies in particular to three-phase warm dielectric superconducting cables. |
