Take a look inside our high-tech Chinese manufacturing facilities. We leverage precision automated systems to ensure strict quality control from raw material processing to final testing.
Understanding the critical priorities of modern grid operators and industrial electrical engineers.
Modern power networks demand step-up and step-down systems optimized for the cyclical output profiles of wind and solar setups. Dynamic load changes require robust mechanical stabilization and advanced low-noise thermal isolation systems.
No-load loss reduction is the cornerstone of efficiency guidelines. Transitioning to Amorphous Alloy cores (such as SCBH15 and SCBH19 series) reduces core losses by up to 70-80% compared to typical silicon steel designs, cutting operating costs over a 30-year lifecycle.
Engineers operating in industrial coastal regions or remote dry plains need custom enclosures. From outdoor pole-mounted cylindrical units with anti-corrosive finishes to indoor IP20 cast resin setups, environmental protection is essential to prevent dielectric breakdown.
China is at the center of the global power transformer supply chain. Henan Pirooz Power Co., Ltd. utilizes these local raw material and industrial advantages to supply high-end, reliable electrical machinery worldwide.
1. Premium Silicon Steel & Copper Core Sourcing: By sourcing raw cold-rolled grain-oriented (CRGO) silicon steel sheets and premium electrolytic copper coils directly from domestic manufacturers, we can manage costs and ensure high permeability and low resistivity in our cores.
2. Modern Automation Ecosystem: Our workshops leverage automated laser cutters, CNC bending machines, and robotic arms to construct transformer tanks and core laminations with micron-level accuracy. This precision maintains tight tolerances and minimizes stray losses.
3. Scalable Custom Fabrication: Our production line is optimized for rapid configuration changes. This allows us to supply specialized designs, such as rectifier configurations, variable tap changers, and compact substations, far faster than traditional manufacturers.
Ensuring seamless installation, commissioning, and grid synchronization in any jurisdiction.
We engineer custom 13.8kV single-phase pole-mounted systems and loop-feed pad-mounted compartmental substations that align with IEEE C57 standards. All enclosures feature anti-tampering designs and comply with ANSI safety requirements.
Our SCB dry-type and S20 oil-immersed distribution lines comply with EN 50588-1 and IEC 60076 specifications. These designs minimize load and no-load losses, helping European customers meet regional energy-efficiency directives.
Our engineers provide clear documentation, electrical schematic details, and remote video consultation. For large infrastructure deployments, we coordinate with local service partners to assist with site testing, oil testing, and initial energization.
We manufacture customized substations built to withstand extreme temperatures ranging from -40°C to +55°C. These systems feature high-altitude insulation design options, heavy-duty dust filtering, and high wind-load ratings.
How our custom transformers and compact substations serve global infrastructure projects.
Underground and pad-mounted substations provide space-saving and touch-safe configurations in highly populated commercial zones, resorts, and metropolitan hubs.
Step-up substations capture output from wind turbines and PV arrays. Our low-maintenance, cast-resin designs withstand transient overvoltages and cyclic loads.
For demanding environments like smelting furnaces, mining operations, and petrochemical plants, our custom-engineered systems ensure high harmonic resistance and thermal safety.
Direct answers to the design and purchasing questions electrical engineers ask most.
Standard SCB series (such as SCB10, SCB11, SCB13) utilize high-permeability cold-rolled grain-oriented silicon steel cores. In contrast, amorphous alloy dry-type transformers (such as the SCBH15 and SCBH19 series) feature a core made of metallic glass.
The primary advantage of amorphous alloy is its atomic structure, which has no crystal boundaries. This reduces no-load core losses (iron losses) by up to 70% to 80% compared to silicon steel, making it ideal for solar installations, schools, and offices where load rates vary throughout the day.
An On-Load Tap Changer (OLTC) adjusts the turns ratio of the transformer while the unit is under load, maintaining a stable secondary voltage despite primary side line voltage variations. This is necessary for grids connected to volatile renewable energy sources, heavy industrial loads, or fluctuating utility feeds.
Off-circuit tap changers (typically providing ±2×2.5% settings) require the system to be de-energized before adjustment. Specify an off-circuit changer only when primary supply voltages remain highly stable and seasonal adjustments are sufficient.
For coastal, high-humidity, or marine environments, we offer customized corrosion protection options:
Every transformer manufactured by Henan Pirooz Power Co., Ltd. undergoes routine tests according to IEC 60076 standards prior to export:
Special tests (such as temperature rise tests and lightning impulse tests) can be requested during the engineering design phase.
Yes. We specialize in engineering and assembling European-style compact substations and American-style pad-mounted systems. These units combine the medium-voltage switchgear (such as SF6 ring main units or air-insulated switches), the distribution transformer, and the low-voltage distribution panel into a single, pre-wired, and tested enclosure.
