The stability of the multi-strand cables under partial current distribution among strands is discussed. The stability is influenced by current sharing process among the strands. Stability tests under controlled current distribution were carried out for some test samples which had various electric resistance among strands. Then numerical analysis of the stability was carried out with simplified electric circuit model simulating current sharing process among strands. The results of the numerical calculations had good agreement with the experimental data. For stability of the multi-strand cables, the electrical resistance among strands which is the key parameter is required to be lower than the normal resistance, corresponding to the length of heated region.
