Premium grade dry-type transformers, neutral grounding resistors, and earthing solutions engineered to comply with Turkish TSE, European CE, and IEC 60076 standards for reliable distribution in industrial hubs and renewable facilities.
A comprehensive overview of Turkey's evolving power distribution framework, industrial growth, and the strategic pivot toward eco-friendly, fire-safe dry-type transformers.
Turkey hosts over 350 Organized Industrial Zones (Organize Sanayi Bölgeleri - OSB) across manufacturing powerhouses such as Kocaeli, Bursa, Gebze, Gaziantep, and Manisa. High equipment density and continuous 24/7 operating cycles necessitate fire-safe, non-explosive cast resin dry-type transformers that require minimal routine maintenance and withstand severe load surges without thermal degradation.
The skyline expansion in Istanbul, Ankara, and Izmir, along with mega-infrastructure projects such as Istanbul New Airport, Integrated Health Campuses (Şehir Hastaneleri), subterranean metro networks, and financial centers, strictly mandates indoor-grade dry transformers with zero flammable liquid risks, toxic gas emission prevention, and self-extinguishing epoxy resin encapsulation.
As Turkey accelerates solar (GES) installations across Central Anatolia and wind farms (RES) across the Aegean and Marmara coasts, dry-type transformers serve as vital step-up and auxiliary distribution units. Turkish EPC contractors actively seek transformers compliant with EU EcoDesign Tier 2 (EN 50541-1 / Regulation 2019/1783) standards to minimize no-load losses.
Hanzhong Xinsanhuan Transformer Co., Ltd. is a professional transformer manufacturer located in Hanzhong City, Shaanxi Province, China—a renowned historical and cultural city known for its strategic geographical location at the heart of the country. Since its establishment, the company has been dedicated to the research, development, design, manufacturing, and service of high-quality power transmission and distribution equipment, providing reliable solutions to customers across domestic and international markets.
With an extensive global export footprint, the company delivers specialized distribution transformers, medium-voltage power transformers, and custom substation units tailored to the exact voltage levels, environmental specifications, and technical standards demanded by utilities, EPC contractors, and industrial developers worldwide, including the fast-growing Republic of Turkey.
The company specializes in the production of power transformers up to 110kV, rectifier transformers, amorphous alloy transformers, oil-immersed distribution transformers, dry-type transformers, compact prefabricated substations, and other customized transformer solutions.
With years of industry experience and continuous technological innovation, XINSANHUAN has developed a comprehensive product portfolio capable of meeting the diverse requirements of power utilities, industrial facilities, renewable energy projects, infrastructure developments, and commercial applications. Every dry-type unit is manufactured utilizing vacuum cast epoxy resin techniques, high-permeability magnetic cores, and premium electrolytic copper windings to deliver exceptional mechanical strength, partial discharge resistance, and thermal efficiency.
Technical advantages engineered into every dry-type transformer to ensure uninterrupted power delivery across Turkish seismic fault zones, diverse coastal-to-continental climates, and strict TEİAŞ / TEDAŞ network requirements.
Recognizing that major Turkish economic corridors (Marmara, Aegean, Eastern Anatolia) are situated along active seismic fault lines, our dry-type transformers are built with reinforced structural steel enclosures, high-rigidity clamping plates, and vibration-damped core-coil assemblies tested to withstand seismic accelerations conforming to IEEE 693 and Eurocode 8 standards.
Our cast resin dry transformers conform strictly to IEC 60076-11 environmental class E2 (heavy condensation and severe pollution tolerance), climate class C2 (transport, storage, and operation down to -25°C in Eastern Anatolian winters), and fire behavior class F1 (self-extinguishing, halogen-free, minimal smoke density for subterranean metro and shopping mall installations).
By employing high-grade cold-rolled grain-oriented (CRGO) silicon steel or advanced amorphous alloy ribbon cores with step-lap mitered joints, our transformers significantly decrease no-load excitation losses and operating acoustic noise, facilitating rapid payback and lowering electricity tariffs for energy-intensive Turkish industrial operators.

Proven electrical distribution performance across specialized Turkish commercial sectors, public transportation networks, and heavy manufacturing clusters.
Dry-type transformers power traction substations and auxiliary station equipment for Istanbul Metro, Ankara Metro, and Izmir Metro lines. Operating deep underground, their complete absence of flammable mineral oils eliminates catastrophic smoke and explosion risks, ensuring continuous passenger safety and adherence to NFPA 130 and European transit safety codes.
Under Turkey's PPP Integrated Healthcare initiative, massive City Hospitals (Şehir Hastaneleri) in Ankara Bilkent, Istanbul Başakşehir Çam ve Sakura, and Adana demand fail-safe distribution with zero harmonic interference. Our cast resin transformers deliver low partial discharge and ultra-quiet operation vital for sensitive medical resonance and intensive care units.
Automotive clusters in Bursa and Kocaeli, alongside heavy metallurgical complexes in Iskenderun and Karabük, expose transformers to non-linear harmonic loads, welder surges, and high ambient metal dust. Our vacuum cast epoxy coils offer unmatched dielectric strength and impenetrable barrier protection against conductive atmospheric dust.
Essential guidance on importing, customizing, and installing dry-type transformers across Turkish industrial and commercial sectors.
