SUPERCONDUCTING CABLE

摘要

The present invention relates to a superconducting cable which minimizes an invasion of external heat due to conduction of a spacer installed in a vacuum unit for vacuum thermal insulation. The superconducting cable comprises: a core unit; an internal metal tube; a thermal insulation unit; an external metal tube configured to maintain an inside thereof in a vacuum state; the spacer; and an external jacket configured to surround the external metal tube.
