Transformers manufacturers in Turkey
Transformers for power and distribution are made by both local Turkish factories and international OEMs with manufacturing in Türkiye; buyers should choose manufacturers based on rated power, voltage class, cooling type and local testing/certification capability. This list gives manufacturers that the search evidence explicitly shows produce transformers in or for Turkey.

What to specify in your RFQ
Manufacturers quote faster and more accurately when your request covers these points.
- Rated power (kVA / MVA)
Specify the required continuous apparent power rating and any short-term overload capability so manufacturers can confirm core and winding design.
- Voltage class (primary/secondary and highest system voltage)
Give nominal primary and secondary voltages and system impulse/phase-to-phase levels so insulation and bushing selection are correct.
- Cooling type / insulation (ONAN, ONAF, dry-type, oil-filled)
State cooling method and whether oil-immersed or dry-type is required, as this affects size, enclosure and maintenance needs.
- Tap changer and vector group
Specify on-load or off-circuit tap-changer range and required vector group (e.g., Dyn11) for system compatibility.
- Standards and certifications
List mandatory standards (IEC, ANSI, local Turkish grid specs) and any required factory inspection or third-party test reports.
- Impedance and short-circuit withstand
Provide required percent impedance and fault-withstand ratings so manufacturers can specify winding conductors and tank/mechanical strength.
- Quantity and delivery schedule
State total quantity, preferred shipment dates and acceptable delivery windows to obtain realistic lead-times and pricing.
