In the era of "Green Energy" and "Smart Grids," the efficiency rating of a power transformer is no longer just a technical specification—it is a critical economic and environmental metric. For global EPC contractors and industrial procurement officers, selecting a transformer with high-tier efficiency ratings (such as S20 or SCBH15) translates to thousands of dollars saved in No-Load Losses and Load Losses over a 20-year operational lifespan.
Henan Pirooz Power Co., Ltd. is leading the shift towards S13, S14, and S20 series oil-immersed transformers, which comply with the latest stringent energy-saving standards in China and the EU. Our R&D team focuses on "Semantic Reliability"—ensuring the intent of the design matches the extreme conditions of the field.
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.
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.
Our products are engineered to meet and exceed IEEE (North America), IEC (International), and EN (Europe) standards. This ensures seamless integration into national grids from Southeast Asia to Latin America.
We provide full documentation for local energy commissions, including Type Test Reports from accredited third-party labs, ensuring your project passes audit on the first attempt.
Beyond the factory gate, we offer localized technical consultancy to help engineers match transformer impedance and cooling classes (ONAN/ONAF) to specific regional climates.
Sourcing from a top-tier Chinese exporter like Henan Pirooz Power offers "Information Gain" that traditional local suppliers cannot match:
By 2025, over 65% of global renewable energy projects will utilize China-manufactured amorphous alloy transformers due to their superior performance in fluctuating load environments.
The "Game Changer" for distribution networks. By using non-crystalline metal, these cores allow for easier magnetization, nearly eliminating no-load losses.
Efficiency is no longer static. Integration of real-time temperature and gas analysis sensors allows for "Active Efficiency Management" and predictive maintenance.
Global regulations are moving toward mandatory Stage 2 compliance, requiring even higher efficiency levels for medium power transformers. We are already ahead of these benchmarks.
Our facility is equipped with state-of-the-art machinery to ensure every transformer meets the highest efficiency ratings. Below is a glimpse into our precision engineering process.
Heavy duty power distribution for smelting, mining, and petrochemical plants where stable voltage and high efficiency are non-negotiable.
Compact European-style substations and dry-type transformers for high-rise residential complexes and commercial hubs.
Custom-built step-up transformers for solar farms and wind parks, designed to handle the variable loads of green energy generation.
A: The rating system primarily refers to energy loss standards. S11 is the traditional standard efficiency. S13/S14 are high-efficiency, and S20 represents the current peak of energy-saving technology, offering significant reductions in both copper and iron losses.
A: Amorphous alloy cores have a disordered atomic structure, which makes them incredibly efficient at magnetizing. This results in no-load losses that are 70-80% lower than standard silicon steel, making them ideal for grids with low average load factors.
A: We use hermetically sealed designs and high-grade insulation oils with high flash points. For dry-type units, our cast resin technology ensures moisture resistance and fire retardancy for humid or tropical environments.
A: Absolutely. We specialize in multi-tap configurations (e.g., 10kV, 11kV, 33kV) and various output frequencies (50Hz/60Hz) to match any national grid requirement.
