In the current global industrial era, the demand for heavy-duty transformers is surging, driven by massive infrastructure upgrades in the US and Europe, and rapid industrialization across Southeast Asia and Africa. As the backbone of the electrical grid, these units facilitate the movement of power from high-voltage transmission lines to end-use industrial applications.
Aging grids in developed nations are being replaced with smart, high-efficiency systems. Heavy-duty transformers now incorporate advanced materials like amorphous alloys and specialized resin casting to ensure long-term stability under fluctuating loads, critical for 24/7 manufacturing environments and mining operations.
The transition to green energy—solar, wind, and EV infrastructure—requires transformers capable of handling bi-directional power flows and harmonizing intermittent energy sources. Chinese exporters are at the forefront of providing custom-engineered substations and pad-mounted solutions for global renewable projects.
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 company operates a modern manufacturing facility with a complete production system covering product design, precision machining, assembly, and full electrical testing. Equipped with advanced production lines and strict quality control procedures, Henan Pirooz Power Co., Ltd. ensures that all products meet international standards and customer-specific technical requirements, maintaining high performance, safety, and durability.
Its 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. These products are widely used in power utilities and heavy industries requiring stable and efficient energy distribution.
China's transformer industry benefits from a complete ecosystem. From the sourcing of high-grade CRGO (Cold Rolled Grain Oriented) steel to the production of high-purity copper windings and insulating resins, every component is sourced locally. This reduces lead times by 30-50% compared to Western counterparts.
By leveraging large-scale automation and optimized engineering, Chinese factories offer heavy-duty transformers that meet IEC and IEEE standards at a significantly lower "Total Cost of Ownership" (TCO). This allows global enterprises to allocate budget towards wider grid expansion.
Unlike rigid production lines in other regions, Henan Pirooz Power provides "Agile Manufacturing." Whether it is a unique climate requirement for the Middle East (high heat resistance) or specialized enclosures for mining, our engineering team can adapt designs rapidly without sacrificing quality.
Our facility utilizes AI-enhanced monitoring and state-of-the-art machinery to ensure every transformer leaving our warehouse is a masterpiece of electrical engineering. From the initial laser cutting of the steel core to the final electrical impulse tests, we leave no room for error.
Our European-style and American-style compact substations are designed for urban developments and high-rise commercial buildings, providing efficient footprint management and safety.
Designed for the harsh environments of mining and metallurgy, our transformers feature reinforced casings and enhanced cooling systems (ONAN/ONAF) to handle heavy particulate matter and vibration.
Step-up transformers for solar farms and wind turbine nacelles, customized to handle the specific harmonic distortion and fluctuating voltage associated with inverter-based power generation.
Looking ahead, the company is committed to innovation, energy efficiency, and smart manufacturing development. By continuously improving product performance and system integration capabilities, Henan Pirooz Power Co., Ltd. aims to become a globally recognized provider of advanced power equipment solutions, supporting the development of modern and sustainable energy infrastructure.
Oil-immersed transformers generally offer better cooling and a longer lifespan for outdoor, high-voltage applications. Dry-type transformers are preferred for indoor use (hospitals, data centers) because they pose zero fire risk and require minimal maintenance.
We strictly follow IEC 60076 standards for transformers. Each unit undergoes a series of routine tests, including winding resistance measurement, voltage ratio checks, and insulation resistance tests before shipment. We also provide full documentation for customs and local regulatory approval.
Yes. Our "Middle East Hot Climate" series is specifically designed with larger radiator surfaces and high-temperature insulation class materials to operate efficiently in ambient temperatures exceeding 50°C.
Typical lead times range from 4 to 8 weeks depending on the complexity and KVA rating. Our vertical integration allows us to prioritize urgent infrastructure projects.
With a growing international footprint, Henan Pirooz Power Co., Ltd. has exported its products to multiple countries and regions worldwide, building long-term partnerships across global energy markets. We invite distributors, engineering firms, and industrial buyers to experience the reliability of China's premier heavy-duty transformer factory.
