A high temperature superconducting cable comprises a cryogenic core, with a superconducting material either inside the cryogenic core or wrapped around the core. A space maintained at a vacuum and functioning as a cryostat surrounds the core; within this space are a separator and superinsulation. A conventional dielectric at room temperature surrounds the superinsulation, and a conventional ground shield surrounds the conventional dielectric. This cable does not require a cryogenic dielectric and is of suitable size and nature to be used in retrofitting conventional cable pipes.

[ What is claimed is:] [1.]1. A high temperature superconducting (HTSC) electrical transmission cable comprising: a core; HTSC material concentrically disposed on said core and operable as a first current conductor for said cable; a cylinder of thermally superinsulating material disposed in an atmosphere of sub-standard pressure and overlying said HTSC material; a dielectric cylinder concentrically overlying and spaced from said cylinder of thermally superinsulating material; a conductive cylindrical shield disposed over said dielectric cylinder; and means for supplying a cryogenic fluid to flow through said core.
