Abstract
Numerical calculations of the AC transport losses under self field were made as a function of current amplitude for models of parallel-conductor cables composed of single-layer or multi-layer configurations of superconducting tapes with rectangular cross sections as the strands in order to obtain a guide for the design and construction of AC power cables with redacted AC transport loss. The loss values of cable conductors are strongly influenced by the tape gap on cylindrical former or the separation between the face-to-face tapes of each layer. These results suggest that improvements in tape and cable structure (i.e., the arrangement of superconducting cores in the cable conductors) is important to suppress the losses generated in cable conductors under AC current transmission.
