Abstract :
YBa2Cu3Oy (YBCO) wire has higher critical current density (Jc) and less degradation in Jc upon application of a magnetic field than (Bi,Pb)2Sr 2Ca2Cu3Ox (Bi2223) powder-in-tube wire. It has good potential for use as a high temperature superconducting (HTS) wire following Bi2223. For many years, we have been studying a process to form biaxially aligned YBCO film on metal-based tape by the inclined substrate deposition (ISD). To date, we have succeeded in fabricating a 6 m-long YBCO wire by a continuous process of the ISD method. We have also investigated performance of the fabricated YBCO wire and the advantages of YBCO wire in its applications to rectifier-type fault current limiter (FCL) and HTS cable
