Methods of ground protections for metal sheath of high voltage single-core cable are introduced briefly in this paper. Meanwhile, taking the ground lead fracture defect for metal sheath of 35kV single-core cable happened in State Grid Qingdao Power Supply Company as an example, combing the situation of critical defect treatments of actual cables, the applications of ground protection for metal sheath of single-core cable, the causes and treating process of the failures are analyzed, and several suggestions for the application of ground protections for sheath of single-core cable are presented.
