During Heating and cooling process of transformer oil Air pressure comming out and going inside the transforemer, This process is called BREATHING of Transformer. Silica Gel Breather helps to avoid entry of humidity and dust inside the transformer oil, humidity is main causes of fluctuation of DIELECTRIC STRENGTH, which is damaging the transformer functionality and out put of current flow. To maintain Humidity Silica Gel Breather plays a very important role in TRANSFORMER.
Silica Gel Breather is made from the finest quality raw material of Orange Silica Gel. We are Silica Gel Breather Supplier and Exporters.

Application

They are available in two varieties viz. Clear View Type and Aluminum Type. The Silica Gel Breather, we provide, is up to the capacity of 2000kva. Our quality speaks for itself it has brought our name among some of the finest Silica Gel Breather Supplier and Exporters. We have two types of Silica Gel Breather one is Blue Silica Gel Breather and other one is Orange Silica Gel Breather.

Useful Area

Breathing Process of Transformer :
Breathing is the process where the transformer Breather-In or Breather our the air from its body due to thermal contraction & expansion of oil mass. When the transformer is loaded or unloaded, the oil temperature inside the transformer tank rises or falls accordingly the air pressure inside the tank changes by either breathing in or breathing out the air. This phenomenon is called "Breathing" of the transformer. Now, the air which is being breathed in contains either dust particles and/or humidity that change the dielectric strength of the oil. For proper functioning of transformer, it is absolutely necessary that dielectric strength of transformer oil remains unimpaired. Hence, it is necessary that, the air entering into the transformer is free from moisture & dust particles.

For proper functioning of transformer dehumidification of Silica Gel crystals & removal of dust particles from breathed air is necessary.
 
Moisture is removed from Silica Gel crystals by heating it inside a ventilated oven at to 150 C, until the color becomes deep blue again.
 
Dusts particles are filtered by the oil in the oil cup.Pressure value for air passage into the breather are: 0.003 Kg/cm inlet or 0.005 Kg/cm outlet.
 
Criteria for Selecting Silica Gel Breather :
Keeping in view the above functions of Silica Gel Breather the main criteria for selecting the breather becomes,
 
Gel changes color from deep blue to pinkish white as it absorbs moisture. By reheating, the Gel becomes free from moisture & hence transformer always breathe in dry air. Visibility of Gel color is very important to decide when to reheat the Gel.
Oil in the oil cup allows dust particles of air to settle in the oil. By changing the oil & cleaning the oil cup air becomes free from dust particles. Visibility of oil level & dust particle in the oil cup is very important to decide when to change the oil.
Transformer should breath from breathing holes (provided in breather) only. If air enters through any other portion of the breather except breathing holes it is called leakage of air.
Leakage of air will lead to entrance of air with moisture & particles in the transformer, which ultimately may lead to formation of spark, and short circuit in the transformer.
