Characteristics of Transformer Moisture Absorbers

Moisture-absorbing performance characteristics:

Efficient moisture absorption: the use of silica gel and other efficient moisture absorption materials, such as fine pore silica gel can be a large number of adsorption of moisture in the air, in the relative humidity of 40%, the adsorption amount> 20%, can effectively reduce the humidity into the air inside the transformer, to maintain the insulating strength of the transformer oil.

Color change indication: color changing silica gel moisture absorber can reflect the degree of moisture absorption intuitively through the color change, such as blue silica gel particles will gradually become purple after absorbing moisture, when the amount of moisture absorption > 23% when the pink, prompting the need to replace or regeneration of silica gel, to facilitate operation and maintenance personnel to keep abreast of moisture absorber's working status, do a good job in the maintenance work.
