Abstract

The widely used multistrand superconducting cables demonstrate quench current degradation in AC mode. Often it happens due to premature quench of one strand. It was suggested that changing of the cable's design may improve the "single strand stability", or stability of a cable in relation to the quench of a single strand. We are checking this idea by testing several AC multistrand superconducting cables made from insulated superconducting strands with different cabling technique. We determined their quench current at different frequencies and current redistribution process in case of the quench of one single strand. The experimental results are presented and influence of the cable design on the "single strand stability" is discussed.
