Abstract :
High current AC superconducting cables are made of numerous co-assembled wires. The assembly mode may be a source of performance degradation, due to different causes, such as wire deformation, mechanical instabilities, heating, anomalous current distribution among the different wires, longitudinal self magnetic field, inadequate junctions. These possible causes have been systematically investigated. Significant results are presented for possible applications of high-performance multi-kA conductors
