Dry Type Transformers

Dry Type Cast Resin Transformers Upto 20 MVA, 36 KV Class

TMC India manufactures VPI & cast resin transformers designed to meet customer specifications and various national and international standards. The range includes distribution & medium power transformers up to 20 MVA, 36 kV class with class F (or) Class H temperature class of insulation. The design and process followed in TMC ensures very low level of partial discharges.

TMC India is the only manufacturer in India to conduct E2-C2-F1 test on transformer as per IEC 60076-11 issued in 2018.

Special Features:
  • E2 C2 F1 certification
  • Foil winding in Low voltage and High voltage windings
  • Copper / Aluminum windings as specified
  • High permeability core laminations with step-lap construction
  • Losses as per latest issue of ECBC 2017
  • Enclosure protection class upto IP44
  • Transformers with OLTC upto 36 KV class

Advantages Of Cast Resin Transformers:

  • Highly resistant to fire and self-extinguishable
  • Non-toxicity of combustion gases in case of fire
  • can be used in highly humid and polluted environments
  • Non hygroscopic insulation provide longer life expectancy
  • Not required to wait long periods to load transformer
  • Not required to provide special arrangement for fire barriers & oil catchment etc.
  • Low installation costs
  • No maintenance required compared to oil filled transformers
  • Low losses of the operation , thanks to the possibility of installing transformers in proximity of the load
  • High resistance to short circuit stress
  • High resistance to over voltage
  • High insulation degree and no partial discharges

Application Areas:

  • Power Distribution
  • Converter/Inverter applications
  • Renewable energy (Wind & Solar)
  • Traction applications
  • Oil & Gas Offshore platform
  • Industrial cranes
  • Seismic Conditions
