Abstract

A 1-km, cold dielectric, high-T_c superconducting (HTS) power cable is being planned in China. The rated voltage and current are 110 kV and 2 kA, respectively. The termination, which connects the superconducting cable conductors at cryogenic temperature to a power transmission line at room temperature and an external cooling system at ground potential, is one of the crucial parts of the superconducting cable system. In this paper, such a termination is designed, including the current lead, the electrical insulation, the condenser cone and the SC-NC joint.
