ABSTRACT:
The present invention offers a sealing-end structure for a superconducting cable. The structure performs, through a bushing, the outputting and inputting of electric power 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 provided with a coolant vessel at the cryogenic-temperature side for cooling the bushing. The coolant 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 a contraction-absorbing portion for absorbing the contraction of the coolant vessel when it thermally contracts by the effect of the coolant. The sealing-end structure for a superconducting cable suppresses the deterioration of the sealing performance of sealing members placed at the boundary between the normal-temperature side and the cryogenic-temperature side over a long period of use.
