Notes:
Having undertaken studies into a lightweight and highly efficient superconductingtransformer for rolling stock, we developed a prototype with a primary winding, four secondarywindings and a tertiary winding using Bi-2223 high temperature superconducting wire. Its primaryvoltage is 25kV, which is widely adopted as the catenary voltage on the world's high-speed lines. Weadopted liquid nitrogen cooling, the weight being 1.71t excluding the refrigerator. The maximumoutput available to maintain superconductivity is 3.5MVA. We also introduce railways in Japan
