Dry Transformers (VPI)

dry transformers using vacuum process impregnation up to 2.5 MVA and 22 kv class

We manufacture and supply dry transformers using vacuum process impregnation up to 2.5 MVA and 22 kv class. Our transformers have following features.

• Use of Nomax insulation for better performance
• Temperature rise of 115 and 150 degree centigrade
• + 5% or - 5% voltage control using taps in steps of 2.5%
• EC grade copper windings
• Air natural cooling with or without fans
• Very low noise within permissible limits of IS/IEC specifications

These transformers are now a days widely where fire hazard is very dangerous like hotels, shopping malls and hospitals and community centers. Dry type transformers are light in weight compared to conventional oil cooled can easily be installed on upper floors and roofs.

Dry Transformers (Resin Cast)

dry transformers using resin vacuum casting up to 1.0 MVA and 11kv class

We manufacture and supply dry transformers using resin vacuum casting up to 1.0 MVA and 11kv class. Our transformers have following features.

• Ourtransformers have following features.
• Lowest risk of fire hazard as oil is not used
• Designed for low operating losses
• Very low noise within permissible limits of IS/IEC specifications
• +5% AND -5% voltage control using taps in step of 2.5%
• Air natural cooling with or without fans
• Highest humidity resistance
• Smaller dimensions and hence light weight
• Can be used in off shore applications and near sea shore
