Recent development of high-temperature superconducting (HTS) cable in Sumitomo Electric Industries, Ltd

Three HTS cable demonstrations in Yokosuka (Japan) by Tokyo Electric Power Company (TEPCO) and Sumitomo Electric Industries, Ltd. (SEI), Copenhagen (Denmark) by NKT and Carrollton (US) by Southwire were successfully implemented. After these successful milestones, the HTS cable development has been entered into the 2nd stage. Three Bi-based cable projects, which are in the real network, have started in US under international collaborations. Also, Asian HTS cable projects are ongoing in Japan, Korea and China. SEI is now engaging in the US Albany Project and KEPRI (Korea Electric Power Research Institute) Project adopting Sumitomo´s 3-core in one cryostat type (3-in-One^TM) HTS cable for distribution network.
