Summary

WHEN SUPERCONDUCTING OXIDES, WHICH HAVE SMALLER LOWER-CRITICAL FIELD VALUES, HC, ARE APPLIED TO A HEAVY-CURRENT POWER TRANSMISSION CABLE, ITS OPERATION IN THE SURFACE CURRENT REGION IS IMPOSSIBLE. FOR A LARGE ALTERNATING CURRENT CAPACITY WITH A RESTRICTED CABLE DIAMETER, OPERATION IN THE REGION ABOVE HC IS REQUIRED FOR AN OXIDE CABLE. IN THE STUDY, THE ALTERNATING CURRENT LOSS FOR AN OXIDE CABLE AT LIQUID-NITROGEN TEMPERATURE IS CALCULATED BY USING THE BEAN MODEL. THE RESULT INDICATES THAT, FOR A 60 MM DIAMETER CONDUCTOR, CRITICAL CURRENT DENSITIES, 10,000 AND 100,000 A/CM2 OF OXIDE SUPERCONDUCTORS ARE REQUIRED FOR 5,000 AND 10,000 A CURRENT-CAPACITY CABLES, RESPECTIVELY.
