Silica Gel for Breather Transformer

Silica gel is an adsorbent that helps in adsorbing the moisture, humidity, odor etc, from the products and helps in maintaining their effectiveness. Silica gel is used in breather transformers for controlling the level of moisture and prevents it from entering the equipment. They are mainly useful in protecting the transformer oil from the damaging effects of moisture. Silica gel blue crystals and orange beads work effectively in this application. They are manufactured by keeping in mind the requirement of the application as per the industry standards.

When load on transformer increases, it gradually increases the flow of current too. With the current increment, heat degenerated into the transformer oil. This result into the less denser transformer oil and moves into the preservation stage. The heat from the hot transformer oil gets started dissolved in the air. This way breather transformer inhales the air containing the moisture.  Such contact of oil and air with moisture may affect the purity of the oil and thus may damage its insulation parts. In order to avoid such type of damage due to entry of moisture into the transformer oil, silica gel is used. When the crystals or beads of silica gel adsorb the moisture, their color turns from blue to pink.
