Design and Current Transporting Characteristics of 80 kV Direct Current High Temperature Superconducting Cable Core

We are now developing a high-temperature superconducting (HTS) dc cable system with the purpose of installing and operating the system on a real power grid in Cheju-island in 2013. As part of the development process, the basic design of the 250 MW HTS cable core was performed. In this paper, the key technical issues focused on the design of dc HTS cable core will be addressed and some important design results to satisfy the requirements of the power network will be presented.
