Transformer Breather Silica Gel Moisture Indicator Desiccant

Transformer Breather Silica Importance: If a transformer comes into direct contact with unfiltered air, it can absorb impurities and moisture from the air, causing the transformer oil to deteriorate. This is particularly true for transformers above 100 kVA, which are larger in size and have a larger surface area, making the transformer oil more susceptible to moisture. Moisture in the transformer not only easily damages the transformer itself but can also compromise the safety, reliability, and stability of other energized lines. Therefore, do not neglect the use of desiccants to better protect the transformer!

　　Usage: Blue silicone has the moisture-proof function of fine-pored silica gel. Its characteristic is that it turns purple as the moisture absorption increases. The on-duty staff can judge whether the silica gel has absorbed moisture by observing the color change inside the respirator. When the colored part of the silica gel accounts for more than one-third of the whole, it should be replaced.
