In the complex landscape of electrical distribution, the Scott-T transformer (also known as a Scott connection) remains a critical bridge between three-phase and two-phase systems. Originally designed to derive two-phase power from a three-phase source, its modern application has expanded into high-speed rail, industrial furnaces, and sensitive electronic testing environments. As a premier Scott-T transformer manufacturer, Henan Pirooz Power Co., Ltd. leverages decades of engineering expertise to deliver solutions that optimize magnetic flux and minimize harmonic distortion.
Unlike standard single-phase taps, the Scott-T connection ensures a balanced load on the primary three-phase supply, even when the secondary two-phase loads are unequal.
Our OEM designs integrate two separate transformers into a single tank, reducing the physical footprint in urban substations and industrial plants.
Utilizing high-permeability silicon steel cores and oxygen-free copper windings to achieve 98.5%+ efficiency ratings.
Henan Pirooz Power Co., Ltd. is a comprehensive electrical power equipment manufacturer integrating research and development, engineering design, production, sales, and after-sales service. The company specializes in customized solutions for power transformers and complete sets of transmission and distribution equipment, providing reliable and efficient electrical products for global energy infrastructure projects.
The global shift toward electrification in transportation and heavy industry has placed the Scott-T transformer manufacturer at the center of the supply chain. In Europe and North America, the upgrading of legacy rail systems requires precise 2-phase power for catenary lines, while in emerging markets like Southeast Asia and the Middle East, industrial growth is driving the need for specialized phase-shifting transformers.
Different regions present unique challenges. In the United States, our customers often require American-style pad-mounted substations with Scott-T internals for data center applications where phase isolation is paramount. In Japan and South Korea, the focus is on high-frequency Scott-T units for induction heating and glass manufacturing. Our ability to provide Custom OEM Scott-T Transformers ensures that local voltage standards (from 110V to 35kV) and frequency requirements (50/60Hz) are met with precision.
Sourcing from China, specifically from clusters like Henan, offers a unique Information Gain for procurement officers. The integration of the entire supply chain—from raw silicon steel processing to final dielectric testing—allows Henan Pirooz Power to offer shorter lead times and higher customization flexibility than Western counterparts. Our facility operates a modern manufacturing system covering product design, precision machining, assembly, and full electrical testing.
Our core product range includes 10kV–35kV oil-immersed power transformers (such as S11, S13, S14, and S20 series), dry-type transformers (including SCB10, SCB11, SCB13, and SCBH15 series), as well as on-load tap-changing transformers, rectifier transformers, and furnace transformers designed for specialized industrial applications.
Looking ahead, Henan Pirooz Power is committed to smart manufacturing. Our Scott-T transformers are now being designed with IoT-enabled sensors that monitor oil temperature, dissolved gases, and load balance in real-time, feeding data into AI-driven predictive maintenance platforms. This technological leap ensures that our "Manufacturer" status isn't just about bending metal, but about providing intelligent energy nodes for the smart grids of tomorrow.
We use cold-rolled grain-oriented (CRGO) steel with multi-level step-lap core joints to reduce no-load losses by up to 30%.
Advanced cooling ducts and high-grade mineral or synthetic ester oils ensure long life cycles even under 120% overload conditions.
Our production follows ISO 9001, CE, and IEC standards, ensuring that every Custom Scott-T Transformer is ready for international grid interconnection.
The energy sector is moving towards Sustainability and Digitalization. As a forward-thinking Scott-T Transformer Manufacturer, Henan Pirooz Power is investing in the development of biodegradable insulating oils and low-noise core architectures. Our products are widely applied in power grid construction, industrial manufacturing, mining, metallurgy, petrochemicals, transportation systems, and renewable energy projects (Solar/Wind).
With a growing international footprint, we have exported to multiple countries, building long-term partnerships across global energy markets. We invite procurement engineers and project managers to consult with our technical team for high-efficiency, cost-effective power solutions that exceed industry standards.
