ABSTRACT:
In order to reduce the AC losses in a superconducting conductor element subjected to an external magnetic field and through which a current flows, tapes of superconducting material of each layer are wound at such a mutual distance that the gap between the superconducting material of adjacent tapes is not smaller than a predetermined minimum value. These elements are particularly useful in three-phase warm dielectric superconducting cables.
