Thermomechanical Properties of 30M HTS Power Cable in DAPAS Project

The 22.9 kV 3 phase 30 m HTS (High Temperature Superconducting) power cable system that contributes to the research for commercial applications was developed as a part of “DAPAS (Dream for Advanced Power system by Applied Superconductivity technologies) Project” in Korea.LS Cable Ltd. has been playing a significant role in design, manufacture, installation, and test of the 30m power cable system. The manufacture and the installation of the cable system were completed in 2004. We performed the initial cool down and the basic operation test of the cable system. We have performed a long period of operation test of the cable system since February 2005. This paper reports the thermo‐mechanical properties of the cable system measured during test.
