Abstract :
A conceptual design of a compact high-Tc superconducting cable was developed by using the Bean model. The experiments suggested that the Bean model provides a rough evaluation of hysteresis loss in high-Tc superconducting wires, which is supposed to be the main component of AC loss. A compact high- Tc superconducting cable was designed using a method based on the Bean model so that it could be installed in existing cable ducts. The results indicated that a compact high-Tc superconducting cable system can increase the power transmission capacity without the need to construct new cable ducts or tunnels. It has also been found that the high-Tc superconducting cable system is acceptable with regard to such system aspects as stability and short-circuit capacity
