The Impacts of Winding Direction on the Electromagnetic Characteristics of CORC Cables

The conductor on round core (CORC) cable spirally wound by second-generation high temperature superconducting (HTS) tapes is considered as a good candidate conductor for high-field magnets due to its good isotropy and low AC losses. Simulation is an effective way to clarify the electromagnetic characteristics of CORC cables. In this work, a 3D finite element model of the CORC cable based on
H
formulation is proposed, which considers the influence of magnetic field on critical current. The influence of the winding direction on the transport current distribution and the AC loss of the CORC cable is investigated based on the proposed model. The simulation results clearly illustrate the electromagnetic characteristics of CORC cables wound in the same and opposite directions. This work provides an important reference for the design and practical application of CORC cables.
