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 October of 1996, EPRI, Pirelli Cable Corporation, and PECO Energy Company performed a joint study to assess the technical and economic feasibility of installing a HTS cable system in downtown Philadelphia. The project team concluded that HTS system could be designed to meet the requirements of a standard underground transmission cable at distribution voltages, and be more advantageous than a conventional system because of better utilization of the existing duct system.
