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.
Industrial power demands are shifting toward intelligence, lower operational losses, and higher environmental resilience. Global procurement teams require highly specialized OEM partners capable of satisfying rigid compliance rules while optimizing energy loss curves.
Rapid integration of renewable energy grids (solar, wind, and storage) demands dual-directional flow control and smart grid compatibility. Standard off-the-shelf transformers often fail to accommodate harmonic distortions. Our custom-designed transformers (such as amorphous alloy and PV box-type configurations) reduce no-load losses significantly, supporting grid decarbonization targets.
Global procurement specialists search for custom OEM partnerships to satisfy specific geographical grid codes (such as IEEE, ANSI, IEC, or CSA). High-performance dry-type transformers (VPI and Cast Resin SCB series) are critical for urban commercial structures, data centers, and heavy industrial plants where indoor safety and zero fire hazards are absolute requirements.
Henan Pirooz Power integrates Industry 4.0 automation, utilizing high-precision laser cutting, mechanical-arm welding, and standardized drying processes. This ensures dimensional accuracy, mechanical robustness, and reliable electromagnetic coil properties, giving us an unmatched cost-to-performance ratio and excellent delivery lead times compared to global competitors.
Every electrical system components and transformer built by Henan Pirooz Power Co., Ltd. undergoes a comprehensive, rigorous assembly-and-test workflow to secure maximum field longevity.
Our custom OEM electric transformers are designed to perform reliably in demanding and extreme operating conditions worldwide.
Continuous uptime requires highly isolated, low-heat generating transformers. Our VPI (Vacuum Pressure Impregnated) and SCB series transformers offer enhanced heat dissipation and robust short-circuit ride-through performance to ensure zero outages for critical IT servers.
We engineer customized outdoor step-up step-down box type substations for solar, wind, and industrial storage projects, safeguarding localized distribution components against environmental stress and dynamic load changes.
We supply high-efficiency rectifier, furnace, and distribution transformers designed to handle extreme electric-arc loads and harsh chemical environments, protecting primary electrical systems from grid feedback anomalies.
To provide an optimized design and accurate pricing, please supply: nominal primary and secondary voltages, power capacity (kVA/MVA ratings), winding material preference (copper or aluminum), cooling type (ONAN/ONAF/AN/AF), impedance percentage, vector group requirements, and any ambient environmental conditions (altitude, indoor/outdoor placement, humidity).
SCB cast resin dry-type transformers use epoxy resin insulation, making them self-extinguishing, highly flame-retardant, and virtually maintenance-free. They are ideal for high-density commercial spaces and indoor installations. Oil-immersed units offer superior heat dissipation, overload capacity, and a longer lifecycle in outdoor, high-voltage utility applications.
All finished transformers undergo rigorous testing at our facilities: winding resistance measurement, voltage ratio checks, phase displacement verification, short-circuit impedance & load loss testing, no-load loss & current measurements, and applied/induced overvoltage withstand tests in compliance with IEC and IEEE standard frameworks.
