An HTS cable demonstration project has started in 2007. The cable has 66kV/200MVA capacity and 200-300 m length. It will be installed and operated at Asahi sub-station in Yokohama in 2011. Bismuth-based HTS wires with twisted superconducting filaments are used for the cable to reduce the AC loss. In 2009, a 30 m cable system has been constructed and tested to verify the assembling technologies of the cable, a joint and terminations and their performance. This paper describes the overview and current status of this project.
