SUPERCONDUCTING CABLE

摘要

Provided is a superconducting cable capable of maintaining a predetermined thermal insulation property without having a vacuum thermal insulation structure. The superconducting cable of the present invention comprises: a cable unit 100, in which a core having a superconductor layer a nd an electrical insulation layer is housed in a core-housing pipe; a thermal insulation member 200 which is provided outside the cable unit and maintained in a non-vacuum state; and a sealing member for preventing the permeation of moisture into the thermal insulation member. By equipping the outside of the cable unit with the thermal insulation member 200 which is maintained in a non-vacuum state, it is made possible to maintain the predetermined thermal insulation property without having a vacuum thermal insulation structure.
