초록
Superconducting cable is using by bundling and twisting with many strands for large current capacity. As a result of the twisting, the magnetic field whose direction is parallel to a sound axis by the transport current of themselves is produced in the cable. Not only the externally exposed longitudinal field but also longitudinal component of self field make a influence on a.c loss and a.c quench current degradation. In this paper, we calculate the saturated region flowing with the critical current density in a strand in case of various twist pitch, transport current and external longitudinal field.
