Abstract

This work investigates the characteristics of CORC cables as current-carrying elements of a superconducting inductive energy storage device. CORC cables based on industrial second-generation HTS (RE)Ba2Cu3O \(_{{7 - x}}\) tapes produced by S-Innovations were wound with one and two layers of HTS tape. The critical current values of the cables were measured in their initial state and after bending deformation at diameters of 50, 40, 23, 15, 10, and 5 cm (simulating coil winding). Numerical models of CORC cables were developed, and their transport and thermal characteristics were analyzed. Subcritical operating modes and potential locations of thermal instabilities in the system were identified, and recommendations for the operation of elements in the design of a superconducting inductive energy storage device were provided.
