Numerical study for ITER superconducting cable of correction coils

The superconducting cable with multi-stage twisted wires is the main component of ITER conductor. This paper proposes the numerical models to describe the pattern of the correction coils (CC) cable and analyze the mechanical properties during cabling. The current models give approximate simulation of space structure and stress–strain curve for the cable. The models could provide theory analysis for design of cable pattern and improve the cabling method.

► Modeling the pattern of ITER CC cable can improve the cabling method.
► The triplet cabling force has more impact on single wire than stage 3.
► The single wire strain in stage 3 is similar to cable strain (stage 3).
► Mechanical model results can improve the cabling method.
