Explore our high-performance power transformation and combined instrument transformer systems built for Turkish solar parks, wind corridors, and municipal distribution substations.
The Republic of Turkey represents one of the most dynamic and rapidly growing electricity markets in the Mediterranean and Eurasian junction. Driven by aggressive national decarbonization targets, industrial expansion across Organized Industrial Zones (OIZ / OSB), and continuous grid modernization overseen by TEİAŞ (Turkish Electricity Transmission Corporation) and regional distribution operators (such as BEDAŞ, GDZ Elektrik, and Başkent EDAŞ), the demand for reliable, compact, and highly precise combined instrument transformers has surged.
An Integrated CT PT Transformer (Combined Current and Potential Instrument Unit) serves as the mission-critical sensory organ of electrical power systems. Combining high-accuracy current transformers (CT) and voltage potential transformers (PT) within a unified, hermetically sealed or cast-resin enclosure, these units drastically minimize substation footprint, eliminate external cabling vulnerabilities, and deliver synchronized measurement signals vital for revenue tariff billing, SCADA telemetry, and digital relay protection across 10kV, 35kV, and high-voltage transmission networks.
Integrates precision current and potential induction within a single rugged enclosure, reducing substation space consumption by up to 50% across compact Turkish urban sites.
Engineered for rigorous EPDK revenue metering standards, offering 0.2S and 0.5S metering accuracy grades over wide thermal spans and harsh grid fluctuations.
Equipped with high creepage porcelain/silicone bushings designed to resist seismic stresses in Central Anatolia and saline sea-fog corrosion along the Aegean & Marmara coasts.
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, including energy contractors, utility providers, and infrastructure developers across Turkey and neighboring regions.
The company specializes in the production of power transformers up to 110kV and 220kV, rectifier transformers, amorphous alloy transformers, oil-immersed distribution transformers, dry-type transformers, compact prefabricated substations, and specialized integrated CT PT metering units. 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.
Our CE-certified integrated CT PT transformers, distribution units, and compact substations are designed to integrate seamlessly with the unique technical demands of the Turkish industrial landscape.
In high solar irradiation zones such as Konya Karapınar, Antalya, and Şanlıurfa, integrated CT PT transformers handle real-time metering and differential protection for multi-megawatt solar booster stations, enduring ambient field temperatures exceeding +45°C without insulation degradation.
From the mega-factories in Gebze, Bursa, and Kocaeli to emerging manufacturing hubs in Gaziantep, integrated CT PT units provide ultra-precise 0.2S multi-tariff sub-metering, helping heavy industries optimize energy efficiency and comply with carbon emission regulations.
Wind farms situated across the Aegean and Marmara windy corridors (Izmir, Balıkesir, Çanakkale) require ruggedized step-up transformers and combined CT PT units that withstand continuous dynamic vibration, harmonic distortion, and coastal saline humidity.
Turkey’s expanding TCDD electrified railway networks require specialized rectifier transformers and combined instrument monitoring units capable of absorbing steep traction load swings and high-frequency transient switching overvoltages.
Fully compliant with IEC 61869-1/2/3, IEC 60076, and European CE directives for seamless integration with Turkish grid switchgear and SCADA platforms.
