The performance of coated conductor YBCO wire is rapidly improving and will be attractive for magnet
applications. Processing this wire into a Roebel cable with either narrow or wide strands gives the possibility to create high current capacity cables and to limit the magnetization AC loss. I will discuss the production and performance of YBCO Roebel cable from commercially available wire. The input wire is magnetically scanned for defects to ensure isotropic Ic in the plane of the tape. Strands are produced by continuous punching and machines have been developed to wind the cable.
Critical current data for 5/2 (5 strands, 2 mm width), 10/2 and 15/5 cables produced from standard 12 mm commercial
YBCO wire are presented. Transport and magnetic loss data is presented which demonstrates the effectiveness of decreased strand width and the transposition of strands for managing AC loss. I will discuss some of the applications driving the development of YBCO Roebel cables.
