Due to its excellent performance in critical current, REBCO high-temperature superconductor (HTS) has important applications in superconducting cables, superconducting magnets and superconducting transformers Quasi-isotropic superconducting strand stacked by superconducting tapes and copper tapes was proposed in this paper. The effects of stacking copper tape with different thicknesses on the critical current of superconducting strand were analyzed. At the same time, the bending and twisting characteristics of quasi-isotropic superconducting strand stacked by 2 mm wide REBCO tapes and copper tapes were studied. The conclusions obtained can provide important data for the practical application of superconducting cable/strand.
