Development and Test of World's First Industrial High-Temperature Superconducting (HTS) Power Cable
Southwire Company has installed the world's first industrial high-temperature superconducting cable system to power three of its main manufacturing plants. The cable consists of three single-phase, 30-m long cables designed to carry 1250 A at 12.4 kV. The cable is cooled by a liquid nitrogen (LN) system that can supply LN at sub-cooled temperatures down to 72 K and at pressures up to 15 atmospheres. The design of the 30-m cables is based upon two 5-m cable prototypes, which were tested at a specially developed facility at ORNL. In addition to critical current and ac loss measurements, simulated fault-current tests were performed at ORNL on the 5-m cables. Cable terminations were designed to allow smooth transition from the cryogenic temperature and pressure environment of the HTS cable to ambient temperature and pressure for copper cables. A dielectric tape material, Cryoflex(trademark), was also developed for use at cryogenic temperatures.
