A wide range of distribution and medium power transformers. These transformers can be free breathing or hermetically sealed. Conventional transformers are fitted with a conservator with breather for free breathing while hermetically sealed are without breathing with bolted cover. Wide range of transformers in accordance to above standards with different combinations can be manufactured. The transformers are generally designed and manufactured to comply with the IEC publications 60076.

In Hermetically Sealed Transformers, the dielectric insulating fluid in the transformer tank is completely sealed and not connected to atmospheric air. This type of transformer is used in applications where the transformer is to be installed in harsh climatic conditions (moist, smoke, polluted, dusty environment, etc.) or where the user prefers a low maintenance transformer. The design avoids air in the transformer tank, thereby avoiding sludge formation and oxidation of the dielectric fluid. Product Feature These Transformers are used in highly humid environment.Perfect for areas with limitation of maintenance service  and confined space conditions.Excellent for compact substation units.Excellent for Highly Polluted Atmosphere.

Hermetically sealed transformer is a transformer design which has no conservator. Here the dielectric insulating fluid in the transformer tank is completely sealed and is in zero contact to the atmosphere. The design avoids air in the transformer tank thereby avoiding sludging and oxidation of the dielectric fluid. Hermetically sealed transformers are totally maintenance free and are particularly suited for use in exposed outdoor environments such as moisture, salt or dust laden atmospheres. They are used extensively in chemical plants, oil and gas terminals where poor accessibility makes regular maintenance impracticable. Transformers immersed in synthetic coolants are suitable for use indoors with adequate ventilation or near to the load center where oil would not be considered environmentally acceptable. Normally these type of transformers are accommodated by devices that measure heat related volume variations. Gas cushion is used to compensate the volume variation due to heat. Normally the gas is nitrogen. This gas is thermally uncoupled from the dielectric liquid

Hermetically sealed oil filled Transformers are widely used these day all over the world for this compactness, excellent heat dissipating properties and longer life. Vardhaman make Hermetically Sealed Transformer is most commonly installed inside Package Sub-stations in India. Salient Feature : Step up and step down transformers. Sealed type Bottled Top With dry air inside. No conservator, so expansion of oil takes place through flexible corrugated walls or compression of dry air. Maintenance free as oil has no contact with external air thus no contamination of oil. Suitable for installation inside package Sub-stations. Compact in size as compared to normal tank with PSR radiators. Excellent heat dissipation properties through corrugated fin walls. Can be with corrugated fins walls or press steel radiators. DGPT2/DMCR relay for multiple Protections is optional. Tailor made designs to meet customer requirement.

We are the prominent Manufacturer, Exporter, and Supplier of Hermetically Sealed Transformers. Our range of Hermetically Sealed Transformers are completely sealed against air and water, hence protecting it from oxidation, humidity and other harmful effects of any leakage in the transformer.
