SUPERCONDUCTING CABLE, REFRIGERANT PIPE AND SUPERCONDUCTING CABLE LINE

摘要

PROBLEM TO BE SOLVED: To provide superconducting cable that load of a refrigerating machine cooling refrigerant is little.SOLUTION: Superconducting cable comprises: a conductor part having a superconduction conductor layer; an inner tube holding the conductor part and filled with refrigerant; a thermal insulation pipe having an outer tube arranged outside of the inner tube and forming a vacuum heat insulating layer with the inner tube; and an outside superconduction conductor layer held in superconducting state in the vacuum heat insulating layer by thermal conduction of the refrigerant through the inner tube.SELECTED DRAWING: Figure 1
