Abstract :
One of the advantages of Bi-2212 is that a high Jc value can be obtained in wires with various shapes and filament configurations. Realization of a high Jc round wire made it possible to fabricate many kinds of cable developed for applications of low temperature superconductors (LTC). We successfully fabricated a 30-strand Rutherford cable using 0.8 mmd round wire. Optimization of cabling factor enables to reduce the Ic degradation at the cable edge. Ic values were about 650-750 A at 65 K in a noninductive winding condition, which corresponds to 11-13 kA at 4.2 K in self-field.
