Description
Summary:The current distribution in a multi-wire round cable subjected to self-magnetic field is considered in this paper. A theoretical analysis of the current distribution process was made. The influence of layer parameters on the current distribution between the layers was determined. The theoretical analysis showed that it was necessary to twist two external layers into different directions with a minimum pitch to increase the current in the internal layers. It was shown that manufacturing round cable with more than two superconducting layers was unnecessary. Formulae are given allowing determination of the current in all layers. The theoretical conclusions were confirmed by the experimental results.
