High-voltage power cable is used more and more in the process of urban modernization in China .The metal sheath generating circulation is a common phenomenon in the high -pressure single-core power cable .The induced voltage model of sheath and the factors influencing the circulation are briefly described , and the impact of sheath protector on sheath circulation is qualitatively analyzed .It is proposed that the sheath circulation will be increased caused by the abnormal sheath protector , and the research is verified through the fault case in 220 kV Houtang transmission line .
