Silica gel for transformer breather

Silica gel is used in breather transformers for controlling the level of moisture and prevents it from entering the equipment. Here, as the silica gel bed acts as a drying agent for the transformer insulation oil, it traps the moisture from the air released as a result of the transformer breathing. Silica gel blue and orange are the best choices for this purpose.
