Abstract

Superconducting cable with multistage twisted strands is an important component of the TF (toroidal field) magnets. A computational model describes the strands twisting pattern at each stage of the cabling. Modeling the pattern of a superconductor cable made of multistage twisted strands is necessary for indigenously developed 30kA NbTi strands CICC. The spatial structure of such superconducting cable is essential for appreciating the load and the performance of CICC at cryogenic temperature. This paper proposes cabling patterns of the strands and gives an approximate position of each stand during the twisting in various stages. These are proposed to be validated with currently developed 30kA CICC at IPR-BARC.
