Abstract

The HTS power cable is composed of 2 layers for transmission and 1 layer for shield. The superconducting tapes of transmission layers and shield layer are wound in a cylindrical shape with a winding pitch. The radius of cylinder and the number of superconducting tapes are decided considering to the transmission current capacity and the critical current of superconducting tapes. The increasement of transmission current capacity will increase in volume of HTS cable system. In this paper, the composition method of super condcuting power cable using the multi-cable is presented. The coated conductor tape can be wound on the smaller cylinder because it has the smaller critical bending diameter than the BSCCO tape. A small-scale cable was composed using the coated conductor tapes and a multi-cable is composed using a small-scale cable considering to transmission current capacity. Even increase of transmission current capacity, this method has advantage that the HTS superconducting power cable can be composed easily. The 22.9 kV and 154 kV supercondcutign power cable was composed using the presented method.
