Engineered to international IEC 60076 & IEEE standards with custom voltage configurations (11kV, 15kV, 33kV to 110V/240V/480V/415V)
The Turkish electrical landscape is undergoing an unprecedented modernization phase. As the bridge between European energy networks (ENTSO-E) and the Middle Eastern power corridor, Turkey’s transmission and distribution authorities—namely TEİAŞ (Türkiye Elektrik İletim A.Ş.) and local distribution companies under TEDAŞ—are demanding higher reliability, lower total cost of ownership (TCO), and strict compliance with eco-design loss mandates.
For Turkish engineering procurement contractors (EPCs), industrial developers in Organized Industrial Zones (OSBs), agricultural irrigation co-operatives in Central Anatolia, and telecom infrastructure providers, sourcing single-phase pole-mounted and pad-mounted distribution transformers from top-tier Chinese manufacturers has become a vital strategic advantage. This technical report provides comprehensive guidance on grid voltage adaptation, thermal endurance, maritime corrosion protection, and loss optimization tailored specifically for buyers in Turkey.
Precision stepping down from 34.5kV, 15kV, or 11kV medium voltage feeders down to single-phase low voltage (110V, 220V, 240V/480V) with ±2x2.5% off-circuit tap changers.
Built using high-grade Cold-Rolled Grain-Oriented (CRGO) silicon steel cores and high-purity electrolytic copper coils to meet Tier-2 energy efficiency standards.
Designed for extreme thermal ambient conditions (+45°C in Anatolian summers) and anti-corrosion C4/C5-M zinc-rich epoxy paint systems for coastal Marmara & Mediterranean sites.

Single-phase distribution transformers play a specialized, high-impact role in Turkey’s electrical topography. Unlike dense urban centers relying on heavy 3-phase grid substations, single-phase units provide localized grid flexibility:
Turkey’s National Energy Plan and 2030 Climate Goals emphasize grid digitalization, loss reduction, and continuous power reliability. Key market developments influencing transformer selection include:
Turkish distribution utilities are actively enforcing eco-design specifications (Ecodesign Tier 2). OEM manufacturers in China must supply transformers with minimized no-load (P0) and load losses (Pk) to reduce carbon taxes and total grid operational overhead.
With Turkey’s rapid surge in wind and solar power generation in the Aegean and Marmara sectors, single-phase step-up/down auxiliary transformers are increasingly specified with ester-filled natural insulating liquids for fire safety and environmental protection.
TEDAŞ is systematically upgrading aging oil-immersed units to compact, maintenance-free hermetically sealed single-phase pole-mounted units that feature low audible noise levels and high lightning impulse withstand capability (BIL up to 170kV).
Backed by over three decades of transformer innovation, our manufacturing facility operates under strict ISO 9001:2015 Quality Management Systems. Every transformer engineered for export to Turkey undergoes stringent quality validation:
Our transformer designs have been type-tested at internationally acclaimed testing authorities, including the Central Power Research Institute (CPRI). Routine tests—such as winding resistance, voltage ratio, phase displacement, short-circuit impedance, separate-source AC withstand voltage, and induced overvoltage testing—are 100% executed in strict compliance with IEC 60076, IS 2026, IS 1180, and IS 11171 standards before dispatch.
Trusted by over 600+ major global utility, defence, infrastructure, and real estate clients, we specialize in high-capacity custom power and distribution units up to 5000 kVA 33kV/34.5kV, special furnace transformers, dry-type units, and ferroresonant constant voltage transformers.
