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 nine HTS tapes were used and set as a similar structure in the cable with a two-layer structure. The critical current of BSCCO tapes are measured against the gap between the tapes in the same layer. The experiments show the improvement of the critical current by optimizing the tape arrangements due to magnetic field interaction between the tapes. We will present the experimental results and discuss the design of the HTS DC cable.
