Abstract :
Southwire Company is operating the world´s first high temperature superconducting (HTS) cable at its corporate headquarters in Carrollton, Georgia. The HTS system consists of three 30 m long single phase cables rated at 12.4 kV, 1250 A and is cooled by pressurized liquid nitrogen. The cable provides power to Southwire´s two main manufacturing plants and the machinery division. The cable was installed and energized on Jan. 6, 2000 for on-line testing and operation. The cables have provided 100% of the customer load for over 9500 hours, including over 2500 hours of unattended operation and is continuing. The HTS cable has proven reliable; it has not caused any power failure since its start up.
