Abstract
Fast quench processes in a 6-strand cable composed of multifilamentary NbTi wires with Cu-Ni matrices and insulation layers are numerically simulated by equations whose applicability was confirmed by good agreement between the theory and experiments for a 2-strand cable, as shown in the previous paper. The simulated results indicate in detail how the transport current commutates among strands and how flux-flow and normal zones grow up in each strand during the process of the fast quench in the 6-strand cable. With the aid of the obtained results, the conditions for occurence of the fast quench and the normal zone length, which is generated by fast quench, are also discussed.
