摘要

High temperature superconducting (HTS) products, such as power cables and motors, have higher transmission capabilities and lower AC loss, and are more compact than conventional counterparts. With these advantages, HTS products are expected to contribute to energy saving and global warming prevention. Sumitomo Electric Industries, Ltd. conducted a national joint R&D project from 2008 to 2012 in order to develop HTS coated conductors and build a 15 m long 66 kV/5 kA class “3-in-One” HTS cable system. We first conducted a short cable test to identify the requirements for the HTS cable and developed an appropriate conductor. Then, we produced a total of 6 km of HTS coated conductors, and built a cable system to be installed into the existing underground conduits of 150 mm in inner diameter. The measured AC loss of our new cable was less than one-third that of a conventional cable even after considering cooling system efficiency. The cable system performance was verified to be stable in a long-term operation test.
