摘要：The present invention offers a sealing-end structure for a superconductingcable. The structure performs, through a bushing, the outputting and inputting of electricpower between a normal-temperature side and a cryogenic-temperature side, where an
end portion of a superconducting cable is placed. The sealing-end structure is providedwith a coolant vessel at the cryogenic-temperature side for cooling the bushing. Thecoolant vessel has a liquid-coolant region filled with a liquid coolant and a gaseous-coolant region filled with a gaseous coolant. The coolant vessel is provided with acontraction-absorbing portion for absorbing the contraction of the coolant vessel whenit thermally contracts by the effect of the coolant. The sealing-end structure for asuperconducting cable suppresses the deterioration of the sealing performance ofsealing members placed at the boundary between the normal-temperature side and thecryogenic-temperature side over a long period of use.
