Power transformers are designed for high voltage transmission and efficient transformation of electrical energy across different voltage levels.
With large capacity and robust structure, they are widely used in power generation plants, transmission substations, and heavy industrial applications.
They are cooled and insulated using high-performance oil and fan-assisted systems.
Technical Specifications:
Power Range: 2.5 MVA – 100 MVA+
Primary Voltage: 36 kV – 245 kV
Frequency: 50/60 Hz
Cooling Type: ONAN / ONAF / OFAF / ODAF
Insulation Class: A
Protection Class: IP00 – IP23 (optional)
Standard: IEC 60076
Applications:
High-voltage transmission lines
Power generation stations (thermal, hydro, wind, solar)
Substations and interconnection systems
Large-scale industrial and infrastructure projects
Cross-border energy transmission systems
Oil-immersed distribution transformers are designed to safely and efficiently convert electrical energy from medium voltage to low voltage. Filled with high-grade mineral oil for insulation and cooling, these transformers feature an expansion tank system offering enhanced thermal performance and easier maintenance.
Technical Specifications:
Power Range: 25 kVA – 2500 kVA
Primary Voltage: 3.3 – 36 kV
Frequency: 50/60 Hz
Cooling Type: ONAN / ONAF
Insulation Class: A
Protection Class: IP00 – IP23 (optional)
Standard: IEC 60076
Applications:
Urban distribution networks
Industrial facilities
Commercial and residential projects
Renewable energy plants
Shopping malls, hospitals, schools
Dry type distribution transformers are designed with resin insulation instead of oil,
providing high fire safety, low maintenance, and environmentally friendly performance.
Thanks to their cast resin windings, they are moisture-resistant and suitable for indoor use in sensitive environments.
Technical Specifications:
Power Range: 100 kVA – 3150 kVA
Primary Voltage: 3.3 – 36 kV
Frequency: 50/60 Hz
Cooling Type: AN / AF
Insulation Class: F or H
Protection Class: IP00 – IP23 (optional)
Standard: IEC 60076-11
Applications:
Indoor low voltage rooms
Shopping malls, hospitals, hotels
Metro and tunnel infrastructure
Wind and solar energy facilities
Industrial and commercial buildings
