In wet weather, dirty composite post insulators are prone to flashover discharge, so they must be cleaned to restore the original insulation level. The general area is cleaned once a year, and the dirty area is cleaned twice a year (once before the fog season).
1, live water flushing and small water flushing two methods. The flushing water, the effective length of the operating rod, and the distance between the person and the live part must meet the requirements of the industry regulations.
2, power failure cleaning power failure cleaning is in the line power failure after the workers boarded the pole with a rag to wipe. If it is not clean, it can be wiped with a wet cloth or scrubbed with detergent. If it is not clean, the insulator should be replaced or replaced with a synthetic insulator.
3, no power failure cleaning is generally the use of a brush or tied to the insulation rod with cotton yarn, on the line to wipe the insulator. The electrical performance and effective length of the insulation rod used, the distance between the person and the live part, should comply with the provisions of the corresponding voltage level, and the operation must be supervised by a special person.
