About Silica Gel Breather
Dehydrating breathers, sometimes referred to as
Silica gel breather,Dessicant breather or Transformer breather, prevent moisture and remove dust particles from ambient air coming into contact with an electrical transformer's insulating liquid when air is breathed in by the transformer and make sure that the air entering into the transformer is free from moisture and dust particles.
Silica gel breathersare filled with
Blue Silica gelor
Orange Silica gel(Indicating Type) which has the moisture absorption capacity and signals the saturation degree by changing its color. Transparent portion of the breather is used to check
Silica gelcolor.Clear View Oil Cup filters the dust particles and allow them to settle in the oil and hence only dry air is breathed in by the transformer.
Silica gel breathersare also used in gear boxes where it allows the transmission to breathe air when the air inside transmission expands or contracts due to heating and cooling of lubricating oil thus preventing unnecessary overheating issue.
Transformer breathersare available in various sizes and the appropriate one is chosen based on the transformer electrical rating and oil quantity.
