We also offer wide range of Dry-Type three phase transformers. Dry type transformers have high mechanical & dielectric strength. Dry type transformers (Vacuum Pressure Impregnated) of 11 KV voltage class have high grade insulation (i.e. class ‘F’ / class ‘H’ / class ‘C’) with bus-bars (Standard) as termination & cable boxes (on request). These generally have AN (Neutral or Natural) / AF (Forced) type of cooling with enclosure protection such as IP21 / IP33 / IP43 / IP00 & Non-ventilated. These are followed as per standards like BIS / IEC / ANSI C57.12.01 / IEEE & IS 1117. Dry type transformers have high dynamic short-circuit strength with good impulse withstand capability which (VPI) ensures void free insulation system. These have better resistance to temperature fluctuations, are immune to polluted atmosphere & are moisture ingress resistant. These are environment friendly & have easy maintenance. These are highly suitable for indoor use & have low fire hazard possibilities.

  • Advantages of Dry-Type Transformers:
  1. These have longer life due to low thermal & dielectric ageing.
  2. These require less space & civil work.
  3. Have better impulse withstand strength & high dynamic short circuit strength.
  4. Special safety features are not required.
  5. Moisture free & immune to polluted atmosphere.
  6. These are eco-friendly, fire-resistant, safe, and explosion-proof.
  7. These are easy to install & easy to maintain & have better appearance.
  8. Have low noise level.
  • Applications for Dry-Type Transformers:

These transformers are suitable where safety, reliability, low noise level, etc. are main concern like:

  • Airports
  • Hospitals
  • Hotels
  • Ports
  • Stadiums
  • Electronic Industries
  • Nuclear & Power plants
  • High rise buildings
  • Chemical & textile plants etc.
  • Metro railways
  • Parks
