Bismuth based high temperature superconductor has discovered by Dr. Maeda at NIMS (National Institute for Materials Science). Just after the discovery of this material, Sumitomo Electric has carried out the R&D on long length and high performance wire, and many application prototypes for more than 20 years. As a wire manufacturing technology, CT-OP (controlled over pressure sintering) process is very effective to make high performance wire. Power cable and ship propulsion motor applications using bismuth based superconducting wire are highly expected.
