High-reliability 10kV, 20kV, and 35kV oil-immersed and earthing transformer units customized for Turkish regional electricity distribution companies (EDAŞ), industrial zones (OSB), and rural electrification projects.
Turkey sits at the crossroads of Europe and Asia, operating one of the fastest-growing medium-voltage (MV) electrical grids in the Mediterranean and Middle East regions.
With Turkey’s 21 privatized regional electricity distribution companies (such as Boğaziçi EDAŞ, Başkent EDAŞ, GDZ EDAŞ, and Toroslar EDAŞ), significant capital expenditure is allocated annually toward replacing aging overhead lines, reducing technical distribution losses, and deploying hermetically sealed pole-mounted transformers.
The surge in licensed and unlicensed Solar PV (GES) and Wind (RES) installations across Central Anatolia, the Aegean, and Southeastern Anatolia requires rugged 20kV and 34.5kV step-up pole-mounted and pad-mounted transformers capable of handling bi-directional load flows and solar inverter harmonic distortions.
Turkey’s 350+ Organized Industrial Zones (Organize Sanayi Bölgeleri) in Bursa, Kocaeli, Gaziantep, and Izmir demand uninterruptible medium-voltage power distribution with high overload capabilities, low acoustic noise levels, and superior short-circuit withstand performance.
Pole-mounted transformers in Turkey must operate across severe climatic contrasts—from the humid, saline maritime air of Izmir and Antalya to the sub-zero freezing winters and high-altitude plateaus of Erzurum and Kars. Our 20kV transformer series is engineered with robust technical parameters aligned with Turkish Electricity Distribution Corporation (TEDAŞ) specifications.
Equipped with high-grade, cold-rolled grain-oriented (CRGO) magnetic steel cores or ultra-low-loss amorphous alloy options, these transformers dramatically minimize no-load losses (P0) and load losses (Pk), achieving compliance with European EcoDesign Tier 2 guidelines widely adopted across Turkey.
Hot-dip galvanized tanks & multi-layer epoxy coating for coastal Mediterranean & Aegean resilience.
Engineered to withstand Zone 1 earthquake acceleration spectra per AFAD & Turkish seismic codes.
Elastic corrugated cooling fins accommodate oil expansion, preventing moisture contamination.
Off-circuit tap changers (OCTC) with ±2x2.5% or ±5% taps for stable regional secondary voltage.
Versatile, compact, and maintenance-free transformer configurations built to support diverse municipal, rural, and heavy industrial infrastructures across Turkey’s 81 provinces.
Providing continuous 20kV to 400V step-down power for deep-well submersible pumps and pivot irrigation across the Southeastern Anatolia Project (GAP) and Central Anatolian agricultural belts.
Serving medium manufacturing plants, textile factories, and automotive parts suppliers in Gebze, Manisa, and Çorlu with low-loss, high-overload capacity distribution units.
Stepping up output from commercial solar string inverters to 20kV/34.5kV distribution feeders with specialized electrostatic shielding and high BIL impulse protection.
Supplying compact, low-noise power for hotel complexes, residential estates, and marina facilities in Antalya, Bodrum, and Fethiye with superior anti-saline finishes.

For Turkish electrical contractors, tender bidders, and industrial plant managers, selecting the right pole-mounted transformer manufacturer requires evaluating crucial technical criteria.
Ensure the manufacturer holds accredited short-circuit withstand, temperature rise, and lightning impulse test reports issued by internationally recognized laboratories (such as KEMA, CESI, or accredited national labs) matching TEDAŞ requirements.
In Turkey’s energy market, electricity tariffs make capitalized loss evaluation critical. Investing in low-loss core designs (A0Ak or Amorphous) yields significant lifetime financial savings over standard high-loss transformers.
Seamless sea freight logistics to major Turkish container ports—including Ambarlı (Istanbul), Mersin, Alsancak/Aliağa (Izmir), and Gemlik—paired with export seaworthy wooden packaging and nitrogen/oil protection ensure defect-free site arrival.

Common questions regarding 20kV and 34.5kV pole-mounted transformer deployment in Turkey’s power network.
In Turkey, medium-voltage distribution systems predominantly use 34.5kV (31.5kV/33kV in legacy zones) and 20kV/15kV/10kV for localized medium-voltage networks, stepping down to 400V (phase-to-phase) / 230V (phase-to-neutral) at 50Hz for low-voltage consumers.
Yes, for pole-mounted ratings up to 2500kVA, hermetically sealed oil-immersed transformers without gas cushions (where flexible corrugated fins absorb thermal oil expansion) are widely favored by Turkish DisCos due to virtually zero maintenance and no silica gel breather replacement requirements.
Our transformers are built with reinforced core clamping structures, heavy-gauge steel tanks, and high-strength porcelain or polymeric bushings rated for dynamic seismic accelerations up to 0.5g ground acceleration, fully conforming to Turkish AFAD earthquake regulations.
We supply units filled with high-grade uninhibited or inhibited mineral oil (IEC 60296) as standard, as well as synthetic or natural ester biodegradable fluids (K-class) for environmentally sensitive projects in national parks or dense tourist centers along the Turkish coast.
