A Superconducting Cable With Curved HTS Tapes

Critical current density is an important parameter reflecting power transmission capacity of HTS cable. Based on the superconducting energy pipeline, a tightly wound cable structure along arc of the pipeline is studied in this paper. Critical current density of electromagnetic thermal coupling is calculated and optimized superconducting cable structure is evaluated. Experimental results are useful to the design of high-temperature superconducting (HTS) cable in energy pipelines.
