Explosion-proof desiccant for transformers
The explosion-proof desiccant for transformers is an air purification device installed at the end of the air intake port of the oil tank of transformers and mutual inductors. It can effectively filter out dust and moisture in the air to maintain the cleanliness and electrical performance of the transformer oil; the main body of the desiccant is clamped between the upper and lower flanges of the transparent glass cylinder with screws. According to customer needs, the cylinder is filled with blue silica gel (desiccant). At the bottom of the desiccant, there is a fully transparent double-layer glass oil cup for transformer oil. A protective cover is added to the outside to prevent external impact and enhance its own strength.
