What are the cleaning and maintenance methods of insulators?

In wet weather, dirty glass insulators are prone to flashover and discharge, so they must be cleaned to restore the original insulation level. The general area shall be cleaned once a year, and the polluted area shall be cleaned twice a year (once before the fog season).

1. There are two methods of charged flushing: large water flushing and small water flushing. The flushing water volume, the effective length of the operating rod and the distance between the person and the live part must meet the requirements of the industry.

2. Power off cleaning refers to that after the line is powered off, workers climb up the pole and wipe it with a rag. If it is not cleaned, it can be wiped with a wet cloth or detergent. If it is not cleaned, replace the insulator or composite insulator.

3. The continuous cleaning is generally to wipe the insulators on the wiring with the insulating rod with a brush or the insulating rod bound with cotton yarn. The electrical performance and effective length of the insulating rod used and the distance between the person and the live part shall meet the requirements of the corresponding voltage level. The operation must be supervised by special personnel.
