A mechanical model of a 24-layer, 66-tape conductor on round core (CORC) cable was developed to investigate its behavior during multi-stage compaction. The effects of inner diameter reduction, copper sheath thickness, and feed rate on the critical current were systematically examined. Results show that excessive diameter reduction or insufficient sheath thickness significantly degrades performance, whereas an optimal feed rate range can mitigate strain-induced losses. The model was further employed to optimize diameter reduction gradients, referring to the incremental decrease in outer diameter during successive compaction stages, which could strongly affect cable performance. Experimental measurements validated the model predictions, showing close agreement and confirming the reliability of the coupled electromagnetic–mechanical approach. These findings provide practical guidelines for the design and manufacturing of CORC cables for high-field superconducting applications.
