In wet weather, dirty insulators are prone to flashover discharge, so they must be cleaned to restore the original insulation level. General area for one year
Clean once, clean the dirty area twice a year (once before fog season).
1. Power failure cleaning
Power failure cleaning is to wipe the workers with rags after the power failure of the line. If it is not clean, it can be wiped with a wet cloth or scrubbed with detergent. If it is not clean, replace the insulator or replace the composite insulator.
2. Cleaning without power-off
Generally, an insulating rod equipped with a brush or tied with cotton yarn is used to wipe the insulator on the running line. The electrical performance and effective length of the insulating rod used, and the distance between the person and the live part should all meet the requirements of the corresponding voltage level, and the operation must be monitored by a special person.
3. Flushing with charged water
There are two methods: large water flushing and small water flushing. The flushing water, effective length of the operating rod and distance between the person and the live part must comply with the requirements of the industry regulations.
