摘要： A superconducting power transmission line is comprised of sections of rigid cryogenic envelope and sections of flexible cryogenic envelope. The rigid sections are comprised of rigid inner and outer tubes having a refrigeration shield located in a vacuum chamber therebetween. The flexible sections are comprised of flexible inner and outer tubes surrounded by reinforcing braid. The rigid and flexible inner and outer tubes are joined together and a refrigeration tube which is in contact with the rigid section's shield is coiled about the inner flexible tube.

摘要： An elongated cryogenic envelope including an outer tube and an inner tube coaxially spaced within said inner tube so that the space therebetween forms a vacuum chamber for holding a vacuum. The inner and outer tubes are provided with means for expanding or contracting during thermal changes. A shield is located in the vacuum chamber intermediate the inner and outer tubes; and, a refrigeration tube for directing refrigeration to the shield is coiled about at least a portion of the inner tube within the vacuum chamber to permit the refrigeration tube to expand or contract along its length during thermal changes within said vacuum chamber.
