FIELD: electricity.SUBSTANCE: invention relates to a superconducting electric power transmission system. Thermally insulated double pipe structure is provided, which can be prevented from substantial displacement of an inner tube relative to an outer pipe due to thermal contraction. Structure includes an inner tube 101, inside which superconducting cable, outer tube 103, which is placed inside an inner tube, inner and outer tubes are thermally insulated double pipes, and support member 104 supports inner tube. Support member 104 supporting inner tube and is attached to inner and outer tubes.EFFECT: invention provides an exception possible misalignment of an inner tube during thermal contraction of an outer tube.18 cl, 8 dwg |
