Abstract
This paper recommends the importance of secondary cable shielding grounding scheme in substations. The appearance of the shield grounding corrosion has been investigated from the substation environment ,secondary cable shielding wire corrosion condition, the corrosion point distribution and the shield current. While the map about corrosion product sample is analyzed respectively from the composition,physical and chemical characteristics,crystal structure and corrosion fracture morphology. According to the shielded wire corrosion reasons,the cause of the corrosion process is concluded which is about the copper clad aluminum shielded wire. This paper lists the simple identification methods of the copper clad aluminum shielded wire,and puts forward some solutions and suggestions about that.关键词
