Description
This paper proposes a novel approach to enhance both the engineering current density and the uniform distribution of the magnetic field in a high-temperature superconducting (HTS) strand. This is achieved by weaving the strand using transpositional REBCO tapes. The H formula is utilized to establish a three-dimensional (3D) Finite Element Model (FEM) in the proposed approach. In the proposed investigation, both numerical and experimental methods are employed to analyze the distribution of magnetic field and critical current at a temperature of 77 K under the magnetic field. Based on the obtained results, it has been observed that the novel high-temperature superconducting (HTS) strand exhibits several favorable characteristics when compared to the strand stacked by three REBCO tapes. These characteristics include larger critical current under the magnetic field.
