The Conductor on Round Core (CORC®) cable is a type of high-temperature superconducting cable that is suitable for power transmission with high current density, accelerator magnets, and high field magnet devices. The CORC cable wound with RE-Ba 2 Cu 3 O 7−δ (REBCO) tapes around a central metallic core can offer isotropic flexibility and good stability. In this paper, two kinds of tapes from different manufactures were selected to study the effect of the winding parameters (winding angle, former diameter, thickness of the superconducting tape, and width of the superconducting tape) on the critical performance of a single-layer CORC high-temperature superconducting cable. Based on the experimental results, a fitting equation was proposed to evaluate the critical current of the cable with different winding parameters. In addition, optimal winding parameters, which provide valuable guidance for designing a high-performance single-layer CORC cable, were proposed.
