Introduction: First generation (1G) Bi-Sr-Ca-Cu-O wire
The first-generation (1G) wire is the workhorse of the present-day HTS industry, with many hundreds of kilometres of tape produced for various demonstration projects, primarily power cables and motors. 1G tape is made by packing Bi–Sr–Ca–Cu–O (BSCCO) superconducting powder into a silver tube. BSCCO is a complex oxide superconductor of cuprate family with critical temperature 115 K. Following a series of rolling and heating steps the end product is a 4-mm-wide tape capable of carrying over 100 A at liquid nitrogen temperature and flexible enough to be used in the electric power applications.
