Discover our certified low-loss electrical power and distribution equipment, customized to support minimal load loss profiles and high dielectric stability.
As global industries pivot toward net-zero emission mandates and high-efficiency smart grids, the demand for low loss transformers has accelerated significantly. Modern grid infrastructure losses account for a sizeable percentage of global energy waste. By integrating high-permeability grain-oriented silicon steel cores or amorphous alloys, low loss transformers dramatically reduce hysteresis and eddy current losses (no-load losses) alongside load losses during high-demand operation.
Regulatory frameworks, including the EU EcoDesign Directives, US DOE standards, and China's updated national green limits, have set mandatory efficiency benchmarks. Industrial sectors such as metallurgy, petrochemicals, rail transportation, and hyperscale data centers now mandate ultra-efficient distribution networks. Meeting these global design rules requires manufacturing partnerships capable of supplying high-reliability machinery that operates at minimal degradation over a 30+ year lifecycle.
Every kilowatt-hour saved in transmission and distribution assets translates directly to reduced greenhouse gas emissions and lower lifecycle operational expenditure (OPEX) for critical infrastructure 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.
In addition to transformers, the company also provides complete electrical system solutions, including high and low voltage switchgear, European-style compact substations, American-style pad-mounted substations, and underground distribution substations. These integrated solutions are widely applied in power grid construction, industrial manufacturing, mining, metallurgy, petrochemicals, transportation systems, and renewable energy projects.
Our factory processes leverage modern automation and mechanical arm precision to guarantee structural stability, optimized core clamping, and exceptional dielectric integrity.

How low loss transformers are deployed across varying climates, installation limitations, and modern grid architectures.
Urban grids require compact, quiet, and reliable solutions. Pad-mounted compact substations and dry-type cast resin transformers (SCB series) fit indoor vaults and dense urban districts where space limits cooling and demands low noise.
Solar PV arrays and wind generation stations experience variable load cycles. Low loss transformers mitigate losses during standby or low-generation intervals, protecting feed-in energy margins for grid operators.
Chemical plants, mining complexes, and furnace systems demand stable isolation and continuous thermal tolerance. Customized isolation, VPI, and rectifier transformers handle load transients and hazardous harmonic distortions.
China's advanced power equipment sector benefits from an integrated raw material supply chain. This guarantees consistent access to top-grade, thin grain-oriented electrical steels and high-quality copper windings. Henan Pirooz Power Co., Ltd. leverages these supply linkages to offer energy-efficient, robust transformers at competitive capital cost terms (CapEx).
By maintaining modern facility certifications and utilizing CNC laser cutting, robotic winding tooling, and automated spray lines, we achieve excellent core alignment and low mechanical noise profiles. This allows us to supply global EPCs and grid developers with bespoke solutions matching complex tender parameters.

For substation managers and utility developers, purchasing a transformer involves evaluating the 30-year lifecycle cost. The primary selection metric is the Total Owning Cost (TOC), calculated as:
Where A and B represent the capitalized cost values per kilowatt of loss, reflecting regional power prices and grid operational hours. Investing in low-loss designs reduces system losses, paying back the initial investment within a few years of high-load service.
With 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. The company continues to expand its production capacity and technological capabilities to meet increasing international demand. 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.
No-Load losses (core losses) occur continuously whenever the transformer is energized, caused by hysteresis and eddy currents in the steel laminations. Load losses (copper losses) vary with the square of the load current, driven by the electrical resistance of the windings. Low loss designs reduce both through high-grade steel selection and optimized winding geometries.
Dry-type cast resin systems are self-extinguishing and suitable for indoor applications with strict environmental and fire safety codes. Oil-immersed units offer higher dielectric performance and efficient natural cooling, making them suitable for outdoor distribution and high-voltage transmission lines.
Amorphous alloy metals feature an irregular, non-crystalline atomic structure. This allows them to magnetize easily, reducing no-load losses by up to 70% to 80% compared to traditional grain-oriented electrical steels.
