Description

technical field

[0001] The invention belongs to an electric power maintenance tool, and in particular relates to a power inspection and maintenance ladder. Background technique

[0002] At present, in the maintenance of electric power, it is often necessary to overhaul the overhead cables located at a higher position. The maintenance ladder is a commonly used tool for climbing up. However, most of the maintenance ladders currently used are made of aluminum alloy, which has good electrical conductivity. When it is necessary to erect When the leaning of the maintenance ladder is electrified due to electrical equipment leakage or other reasons, or when the maintenance ladder is misoperated and touches the live equipment, it is very easy to electrically injure the operator or cause a short circuit of the electrical equipment due to the conduction of the maintenance ladder, resulting in a safety accident. In addition, the currently used maintenance ladder does not have the functi...
