Hermetic-Type Oil-Immersed Transformers – A+ Class (TEDAŞ MLZ 99/032-E)

The flagship range. A+ class hermetic-type transformers deliver the highest energy efficiency available under TEDAŞ MLZ 99/032-E – significantly reducing no-load and load losses compared to standard classes, with measurable lifetime electricity savings. Hermetically sealed against the atmosphere, completely filled with oil under vacuum, with no expansion tank: the transformer oil never contacts air, eliminating moisture absorption, oil oxidation and the need for periodic oil maintenance. Ideal for distribution centers, organized industrial zones (OSB), wind farms, solar power plants, hospitals, hotels and inner-city distribution applications.

  • 50 kVA – 2500 kVA – 28.5–36 / 0.4 kV three-phase hermetic transformers
  • TEDAŞ MLZ 99/032-E specification compliance (A+ energy efficiency class)
  • ONAN natural oil cooling, no expansion tank, no periodic oil maintenance required
  • Pressure relief valve and hermetic protection relay included
  • Optional automatic on-load tap changer (OLTC) and idle tap changer versions
  • Suitable for indoor and outdoor installation in compact substations

Hermetic-Type Oil-Immersed Transformers – AOAk Class (TEDAŞ MLZ 99/032-D)

The cost-effective standard range. AOAk class hermetic transformers comply with TEDAŞ MLZ 99/032-D and provide reliable, durable performance for projects where the additional efficiency benefit of A+ class is not the primary driver. Same hermetic construction principles as the A+ range – fully sealed, oil-filled under vacuum, no expansion tank, no periodic oil maintenance – at a more accessible price point. Ideal for construction sites, factories, irrigation projects and general-purpose MV/LV distribution centers.

  • 50 kVA – 2500 kVA – 28.5–36 / 0.4 kV three-phase hermetic transformers
  • TEDAŞ MLZ 99/032-D specification compliance (AOAk standard class)
  • ONAN natural oil cooling, fully sealed hermetic design
  • Compact dimensions for tight installation spaces
  • Standard pressure relief valve and protection relay

Dry-Type Cast-Resin Transformers – TEDAŞ MLZ 99/031-B & IEC 60076-11

For applications where oil is not permitted – high-rise buildings, hospitals, data centers, shopping malls, marine vessels, mining facilities and underground installations. ASTOR dry-type transformers use cast-resin (vacuum-cast epoxy) coils with no flammable insulating liquid, delivering F1 fire behaviour, E2 environmental class and C2 climatic class. Available in two specification levels: TEDAŞ MLZ 99/031-B (Turkish market requirement) and IEC 60076-11 (international export specification). Optional cooling fan kits provide forced-air cooling for AF (Air-Forced) operation up to 50% capacity boost.

  • 400 kVA – 2500 kVA – 28.5–36 / 0.4 kV three-phase dry-type transformers
  • TEDAŞ MLZ 99/031-B specification for Turkish-market projects
  • IEC 60076-11 specification for international export markets
  • F1 / E2 / C2 fire, environmental and climatic classification
  • Optional cooling fan kit (250 kVA – 1250 kVA and 1600 kVA – 2500 kVA versions)
  • Optional fan control panel for automatic temperature management
