Abstract

Bi-2223 round shaped strands were developed for realizing a HTS transposed cable conductor. The maximum critical current density (J_c) of a short sample was 3.2 × 10⁸ A/m² without external magnetic field at 77 K, and the J_c of 50 m class long length strands was 1.6 × 10⁸ A/m² at the same condition. We prepared subcables consisted of the round shape strands. Using subcables, a HTS transposed conductor was fabricated, and investigated the DC and AC performance. The conductor I_c was 900 A as 10^-4 V/m (77 K, 0 T) criterion. Measured AC loss was compared with the theoretical loss considering of the magnetic field distribution and J_c-B dependence of the strand. It was confirmed that the experimental and theoretical values were nearly identical.
