High temperature superconductivity: A joint feasibility study for a power application with HTS cable by South Carolina Electric and Gas. Final report

Technical Report ·
OSTI ID:354927
High temperature superconductivity (HTS) cables have the potential to revolutionize the power delivery industry by reducing costs and maximizing the use of existing conduits for underground transmission. In 1986 a class of ceramic materials showing superconductivity slightly below the temperature of liquid nitrogen was discovered and, when used in cables, can carry two to five times more current than conventional cables of comparable size. In June 1996, EPRI, Pirelli Cable Corporation, and South Carolina Electric and Gas (SCE and G) performed a joint study to assess the technical and economic feasibility of installing a HTS cable system on a highly loaded SCE and G underground circuit. It was concluded that a HTS system could be designed to greatly exceed the requirements of a standard underground transmission cable.
