ABSTRACT:
A ceramic wire superconducting cable is provided having porous expanded polytetrafluoroethylene insulation, a superconductive ceramic tape "conducting" layer having openings at prescribed intervals and a high strength polytetrafluoroethylene fiber protective layer. The components covering the cable are porous permitting liquid nitrogen to permeate and directly contact with the superconductive cable.
