Patent ID: 7038141

Claim:
A superconducting power cable comprising: a central superconductivity core comprising a first flexible corrugated pipe; a plurality of stainless steel tape layer around the core; a plurality of copper tape layer surrounding the stainless steel tape layer; a plurality of superconducting material on the copper tape layer; a wrapping tape comprising an insulating material on the superconducting material; a vacuum thermal insulation system comprising a flexible corrugated pipe on the insulating material; a plurality of thermal insulation layer applied on the periphery of the flexible corrugated pipe; a second flexible corrugated pipe on the thermal insulation layer, which forms a vacuum space; a braided stainless steel mesh on the external wall of the second flexible corrugated pipe; a first semiconducting shield around the stainless steel mesh surface; an electric insulation on the first semiconducting shield; a second semiconducting shield on the electric insulation; a metal shield on the second semiconducting shield; and a protective casing on the metal shield.
