The current distribution in the Cable In Conduit Conductor (CICC) cables has a relevant impact on the cable stability margin. Therefore in the research & development and testing phases of such cables, the study of the current profile behaviour under various operating conditions is a quite important issue. As a matter of fact, CICC cables could be designed by assuming that the current is evenly shared among the strands; however in actual operating conditions, some regions of the cable may be interested by anomalous distributions, leading to possible local current sharing regimes, and eventually to the premature quench of the cable with currents lower than the expected critical figure. The complete physics grasp of such phenomenon is not yet clear, and a number of experimental and theoretical studies aimed at clarifying it are currently under progress [1,2].

Abstract
The current distribution in the Cable In Conduit Conductor (CICC) cables has a relevant impact on the cable stability margin. Therefore in the research & development and testing phases of such cables, the study of the current profile behaviour under various operating conditions is a quite important issue.
