摘要： A superconducting cable (1) includes a superconducting cable core (2) and a corrugated pipe (21) storing the superconducting cable core (2). The superconducting cable core (2) has a corrugated pipe (11), a superconductor (12) provided on the outer peripheral side of the corrugated pipe (11), and a heat insulating pipe (23) stored in the corrugated pipe (11) and having a smooth inner peripheral surface. A coolant flows through a flow passage (FP1) formed in the heat insulating pipe (23) and then flows through a flow passage (FP2) formed between an outer peripheral surface of the corrugated pipe (11) and an inner peripheral surface of the corrugated pipe (21).

摘要： A superconducting cable comprises a superconductor 60, two or more coolant passages including an outgoing coolant passage 12 and a returning coolant passage 14 that transfer a coolant that cools the superconductor, and a heat insulating pipe 10 inside which the superconductor 60 and the coolant passages are formed. For the coolant passages, by a double structured tube of an inner tube 6 and an outer tube 8, the outgoing coolant passage 12 is formed in the internal space of the inner tube 6 and the returning coolant passage 14 is formed in the space between the inner tube 6 and the outer tube 8, the inner tube 6 is formed between the outgoing coolant passage 12 and the returning coolant passage 14 of a heat insulating material, the superconductor 60 is disposed on the outer circumferential side of the inner tube 6, and the superconductor is cooled by the coolant that flows through the returning coolant passage.
