Is There Any Damage, Rupture, Or Discharge Marks On The Insulation Sleeve Of The Distribution Transformer

If the insulation sleeve is not cleaned for a long time, or there are damaged cracks and discharge marks, the leakage current of the insulation sleeve will increase due to humid air in rainy or foggy weather, and the insulation will decrease, leading to ground flashover. In addition, severe scaling of the insulation sleeve, as well as large fragments and cracks on the insulation sleeve, can also cause flashover or explosion accidents. To solve this phenomenon, besides observing the insulation sleeve itself, attention should also be paid to the accumulation pattern of the sleeve, such as wind direction and surrounding environment, in order to do a good job in cleaning.
