摘要：
A High Temperature Superconducting (HTSC) cable is expected to transport large electric power with a compact size because of its high critical current density. A 30m 66kV-1kA HTSC power cable system has been developed. The critical currents measured at 67K similar to 80K are 1800A similar to 800A. At the loading test, the 40kV-500A was successfully applied with a constant tan delta and capacitance. During the test, the temperature and pressure of circulating liquid nitrogen were controlled to 72K and 20kPa, respectively. Heat leak through the thermally insulated pipe was estimated as 1.5W/m, which is good performance for a long HTSC cable.
