Document Type and Number:
Japanese Patent JP2523630
Kind Code:
B2
Abstract:
PURPOSE:To obtain a superconductive cable with high performance by using an oxide superconductor for a cable utilized for power transmission. CONSTITUTION:Two superconductive segment conductors 2, 2 with a fan-shaped circular cross section and two ordinary conductive segments 3, 3 with a fan- shaped circular cross section are combined in turn to form a superconductive cable 1 cylindrically as a whole. This superconductive segment conductor 2 is constituted by stranding, molding, and compressing many superconductive wires 4, and the superconductive wire 4 is constituted of a linear superconductor 5 and a film layer 6 made of copper and provided on its outer periphery. When a refrigerant such as liquid nitrogen is fed into a refrigerant passage 8 and the superconductor 5 of the superconductive segment conductor 2 is cooled to the critical temperature or less, a current is allowed to flow in the superconductor 5 with no loss.
