In wet weather, dirty insulators are prone to flashover and discharge, so they must be cleaned to restore the original insulation level. The general area is cleaned once a year, and the polluted area is cleaned twice a year (once before the fog season).
1. Power off cleaning
Power off cleaning means that after the line is cut off, workers climb on the pole and wipe it with rags. If it cannot be cleaned, it can be cleaned with wet cloth or detergent. If it cannot be cleaned, replace the insulator or composite insulator.
2. Uninterrupted cleaning
Generally, the insulator is wiped on the running line with an insulating rod equipped with a brush or bound with cotton yarn. The electrical performance and effective length of the insulating rod used, as well as the distance between the person and the live part, shall comply with the provisions of the corresponding voltage level, and special personnel must be assigned to monitor the operation.
3. Charged water flushing
Large water flushing and small water flushing. 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.
