PROBLEM TO BE SOLVED: To provide a superconducting cable, particularly a superconducting cable having a core material and a multi-layer superconductive conductor with a reduced alternating current loss through an accurate current distribution analysis. SOLUTION: This superconducting cable comprises a core material, a conductor layer with a supercondcuting wire wound spirally around the core material, an electrically insulated layer, and a magnetic shielding layer around which a superconducting wire is spirally wound. In the superconducting element wire the shortest pitch is disposed on the outermost layer of the conductive layer while the longest pitch is disposed on the outermost layer of the magnetic shielding layer. |
