Abstract:We have been studying the effect on the performance of BSCCO tapes for the superconducting DC power cables by critical current measurements. In the present experiments several HTS tapes were used to simulate a cable structure used in the DC power transmission and distribution lines with a two-layer structure. Their critical currents are measured by varying the space gaps between the tapes in the same layer. The experiments show the improvement of the critical current by optimizing the tape arrangements due to the correlated magnetic field interaction by the applied current in the tapes.
