Abstract
The important merit of Bi-2212/Ag wire is to apply cable as round wire state. Bi-2212 high Tc superconducting wires were fabricated in order to apply Rutherford cable near the future. Various Ag ratio from 0.22 to 0.42 of Ag tubes for PID (powder-In-Tube) process were used to investigate the workability and to prevent breakage of filaments during drawing. KERI and Nexans Korea manufactured Rutherford cabling machine by ourselves. Rutherford cables with 20 - 30 strands could be fabricated by this machine. The shape of Rutherford cables were satisfied. The critical current of Bi2212/Ag round wire with 847 filaments showed 400 A at 4.2K and self field.
