A Comprehensive Pioneer in Advanced Electrical Grid Infrastructure and Systems Integration
Henan Pirooz Power Co., Ltd. is a globally recognized, comprehensive electrical power equipment manufacturer integrating cutting-edge research and development, engineering design, precision production, global sales, and complete lifecycle after-sales support. The company specializes in delivering highly customized, end-to-end solutions for medium-to-high voltage power transformers and integrated high/low-voltage transmission and distribution equipment. Our core mission is to provide resilient, efficient, and cost-effective electrical hardware designed to support modern energy transition initiatives and global infrastructure projects.
Operating from a state-of-the-art manufacturing campus, our facility employs a fully integrated production ecosystem. This ranges from precision structural sheet metal fabrication, core wind assembly, to rigorous high-voltage electrical testing procedures. Backed by automated production systems and a strict quality control matrix, Henan Pirooz Power Co., Ltd. guarantees that every transformer leaving the production line conforms strictly to international frameworks (including IEC, IEEE, ANSI, CE, and GB standards). We engineer our systems to guarantee operational safety, thermal stability, and low-loss profiles under the most demanding loading conditions.
Our expansive catalog encompasses 10kV to 35kV oil-immersed power transformers (including the high-performance S11, S13, S14, and ultra-low loss S20 series) and premium dry-type distribution transformers (such as the SCB10, SCB11, SCB13, and amorphous alloy SCBH15 series). For industrial applications demanding specialized thermal profiles, we engineer custom on-load tap-changing (OLTC) transformers, heavy-duty rectifier transformers, and furnace transformers. These units are designed to withstand harmonic distortion and structural mechanical vibrations typical of heavy metallurgical and chemical operations.
Beyond isolated transformers, Henan Pirooz Power Co., Ltd. manufactures integrated power distribution platforms. These include custom high/low-voltage switchgears, space-saving European-style compact substations, utility-grade American-style pad-mounted substations, and robust underground distribution cabinets. These comprehensive systems find wide application in global grid construction, large-scale industrial manufacturing plants, mining facilities, petrochemical hubs, public transit grids, and solar/wind renewable integration schemes.

An engineering comparison of structural efficiency, insulation mediums, and thermal management methods.
Three-phase transformers serve as the foundational nodes of modern energy grids. When selecting equipment for industrial, commercial, or municipal applications, the choice typically hinges on balancing operational environment constraints, safety mandates, and efficiency curves.
| Parameter | Oil-Immersed (S11, S13, S20 Series) | Dry-Type Cast Resin (SCB10, SCB13, SCBH15) |
|---|---|---|
| Insulation Medium | Mineral Insulating Oil / Biodegradable Esters | Solid Epoxy Resin Matrix & Air Class F/H |
| Thermal Performance | Superior (ONAN / ONAF cooling configurations) | Convection cooled, dynamic air cooling fans (AN/AF) |
| Fire Safety Profile | Requires containment bunds & fire suppression | Self-extinguishing, fireproof (Zero risk of explosion) |
| Primary Application | Outdoor Substations, Mining, Heavy Utilities | Indoor Buildings, Subways, Data Centers, Hospitals |
| Maintenance Overhead | Periodic dissolved gas analysis (DGA) & oil filtering | Minimal (dust removal & connection inspection) |
| Overload Capacity | High transient overload capability due to thermal mass | Moderate, relies on forced cooling blowers |
Our manufacturing philosophy leverages cold-rolled grain-oriented (CRGO) silicon steel sheet designs to construct transformer magnetic cores. Through precise alignment of the magnetic domains along the rolling direction, we achieve exceptionally high permeability and minimal hysteresis loss. In our ultra-efficient models like the S20 and SCBH15 (Amorphous Alloy), we substitute traditional CRGO steel with amorphous alloy ribbon. The non-crystalline structure of amorphous metal exhibits near-zero magnetic resistance, cutting no-load losses by up to 70% to 80% compared to standard configurations. This translation of advanced material science directly reduces operational costs for utilities and private microgrids, helping operators meet stringent environmental mandates.
How Henan Pirooz Power adapts core products to address unique operational demands across global industries.
Wind and solar installations present challenging load profiles, characterized by frequent load cycling and transient voltage surges. Our 1250kVA Pad-Mounted Transformers are engineered with specialized low-loss, high-insulation windings designed to stabilize voltage outputs. We use electrostatic shield configurations to prevent high-frequency inverter harmonics from coupling back into the high-voltage transmission grid.
Mining environments require equipment that can withstand high vibration, ambient dust, and moisture ingress. The ACT 2500kVA Oil-Immersed Transformer with integrated Oil Conservator features robust steel structural reinforcement, heavy-duty anti-corrosive powder coatings, and hermetically sealed tanks. This configuration guarantees complete isolation from atmospheric coal dust and corrosive chemical fumes, preventing dielectric breakdown.
For high-rise residential properties, medical centers, and high-density data servers, fire prevention is critical. Our Box-Type Resin Cast Epoxy Dry-Type Transformers utilize a self-extinguishing Class F insulation matrix. This eliminates the risk of catastrophic fires or leakage of hazardous dielectric fluids, ensuring complete compliance with building safety regulations.
