Hermetic Power Transformer (up to 245 kV)

Hermetically Sealed Power Transformers

With the ongoing changes in the energy supply industry, power transformers are expected to maintain a higher degree of operation and longer service life. The hermetically sealed transformers, without oil conservator, are a field-proven answer to these needs, combatting the problems of load/temperature-dependent aging that oxygen and humidity from atmosphere would otherwise accelerate.

Main Characteristics

  • Ratings up to 200 MVA
  • Voltage up to 245 kV
  • On Load Tap Changer with vacuum switch
  • Complies with international standards
  • Special design of the radiators, patented by AREVA T&D, to accommodate the thermal expansion of the transformer oil.

Key Benefits

  • Substantially longer service life
  • Higher load ratings
  • Reduced maintenance thanks to:
    • lower oil aging
    • no dehydrating breather
    • no hydro-compensator
    • no contact erosion
  • Low lifecycle cost
