YBa2Cu3Oy (YBCO) wire has higher critical current density (J(c)) and less d
egradation in J(c) upon application of a magnetic field than (Bi,Pb)(2)Sr1C
a2Cu3Ox (Bi2223) powder-in-tube wire. It has good potential for use as a hi
gh temperature superconducting (HTS) wire Following Bi2223, For many years,
we have been studying a process to form biaxially aligned YBCO film on met
al-based tape by the Inclined Substrate Deposition (ISD), To date, we have
succeeded in fabricating a 6m-long YBCO wire by a continuous process of the
ISD method. We have also investigated performance of the fabricated YBCO w
ire and the advantages of YBCO wire in its applications to rectifier-type f
ault current limiter (FCL) and HTS cable.
