摘要

1. A superconducting cable including a superconducting conductor layer and a cooling fluid duct cooling the superconducting conductor layer to a superconducting state, said superconducting cable comprising: a core having said superconducting conductor layer and an insulating layer; a cooling fluid conduit forming said duct cooling medium and arranged parallel to the core so as to cool said superconducting conductors th layer; and - a host tube of said core and said coolant tube. 2. The superconducting cable according to claim 1, wherein the plurality of said cooling fluid tubes are twisted so that they surround the outer periphery of said core. The superconducting cable according to claim 2, wherein said plurality of cooling fluid tubes surrounds the plurality of said cores. The superconducting cable according to claim 2 or 3, wherein: said core and a plurality of coolant tubes twisted to surround the outer periphery of the core are combined to form a composite core bundle, and a plurality of composite core bundles are provided in said host tube. . The superconducting cable according to claim 2 or 3, in which: said core and a plurality of said cooling fluid tubes twisted to surround the outer periphery of the core are combined to form a composite core bundle, and a plurality of additional cooling fluid tubes provided with
