Abstract
Disclosed herein is a high-vacuum-maintaining structure of a superconducting cable. The superconducting cable includes inner and outer metal tubes, and spacers disposed between the inner and outer metal tubes for spacing them by a prescribed distance. To the spacers is attached a gathering material, which serves to adsorb residual gas between the inner and outer metal tubes, thereby maintaining the superconducting cable in a high-vacuum state for a long time, improving thermal insulation performance of the superconducting cable, and reducing cooling costs and maintenance costs required for vacuum pumping thereof.
