Development of REBCO HTS Power Cables

AbstractA Japanese national project, called “Materials & Power applications of Coated Conductors (M-PACC)”, started in FY2008. In this project, we are developing 66kV/5 kA large current high temperature superconducting (HTS) cable and 275kV/3 kA high voltage HTS cable using REBCO tapes. These HTS cables are expected as a compact size with large capacity and low loss power transmission. We have examined AC loss, thermal characteristics of the cables under over-current, the optimum cable design and so on. After the design studies and elemental tests are completed, long cable systems will be built for verification purposes. This paper described the overview and current status of these HTS cables development in the M-PACC project. (PACS: 84.71.Fk
