Abstract

This invention provides a terminal structure of a superconductive cable, wherein the gas sealing performance of a seal positioned in the boundary between the normal temperature side and the extremely low temperature side can be prevented from deteriorated, even after a long term usage. The terminal structure of present invention comprises: a terminal of the superconductive cable (100), a bushing (10) electrically connected with the superconductor (100a) of the cable (100), and a cooling medium reservoir (11) used for accommodating the terminal and the bushing (10). Within the cooling medium reservoir (10), liquid nitrogen layer (13) is neighboring to the extremely low temperature side, while the nitrogen gas layer (14) is neighboring to the normal temperature side. In the nitrogen gas layer (14), the spacing t between the inner surface (11a) of the cooling medium reservoir (11) and the outer circumference of the bushing (10) can maintain the nitrogen gas in gaseous state without using a pressure booster device to carry out pressurizing, and the spacing t is made to have a size which can cause the equilibrium between the pressure of the nitrogen gas and that of the liquid nitrogen.
