Henan Pirooz Power Co., Ltd. stands as a titan in the electrical power equipment sector, serving as a comprehensive manufacturer that seamlessly integrates R&D, engineering design, precision production, and global export services. We specialize in providing high-end, customized solutions for power transformers and full-scale transmission and distribution equipment.
Our modern manufacturing facility is a testament to industrial excellence, featuring a complete ecosystem that spans from the initial design phase to precision machining, final assembly, and rigorous electrical stress testing. By adhering to E-E-A-T principles, we ensure that every unit leaving our facility not only meets but exceeds international standards (IEC, ANSI, IEEE) and specific regional technical requirements.
In the realm of oil-immersed transformers, the Conservator Tank is the lungs of the system. Its primary role is to accommodate the volumetric expansion and contraction of the insulating oil due to temperature fluctuations during operation. Unlike hermetically sealed units, conservator-type transformers allow for a controlled "breathing" process.
Technical Edge: Our conservators are equipped with advanced moisture-absorbing breathers (silica gel) or air-cell diaphragms. This prevents atmospheric oxygen and moisture from coming into direct contact with the oil, significantly slowing down the oxidation process and preserving the dielectric strength of the insulation. This engineering choice extends the transformer's lifespan by up to 30% compared to traditional open-air designs.
Our facility utilizes state-of-the-art automation to ensure consistency and reliability.
China is home to the world’s leading CRGO (Cold Rolled Grain Oriented) silicon steel producers. By sourcing premium magnetic materials locally, Henan Pirooz Power reduces core losses and noise levels while maintaining cost-efficiency that Western manufacturers cannot match.
Our supply chain ecosystem allows for rapid prototyping and customization. Whether you need a 167KVA pole-mounted unit for rural electrification or a 2500kVA industrial transformer, our lead times are 40% faster than the industry average.
As seen in our use of robotic mechanical arms and laser cutting machines, we eliminate human error. This ensures that every winding, tank welding seam, and insulation layer is executed with sub-millimeter precision.
Modern power grids are shifting toward decentralized energy. Our S11 and S13 series oil-immersed transformers are engineered to handle the harmonic distortions and variable loads characteristic of photovoltaic and wind farms. With robust conservator tanks, these units manage the rapid temperature shifts common in outdoor solar fields.
In harsh environments like mining sites and petrochemical plants, reliability is non-negotiable. Our rectifier and furnace transformers provide stable voltage for high-current industrial processes. The use of high-grade copper/aluminum windings ensures thermal stability during 24/7 heavy-duty operations.
We provide integrated solutions including European-style and American-style compact substations. These units combine the transformer, high-voltage switchgear, and low-voltage distribution into a single, space-saving enclosure—ideal for modern metropolitan residential developments.
Growing demand for biodegradable ester oil transformers to reduce environmental impact in case of leaks.
Smart transformers equipped with sensors for real-time monitoring of oil temperature and dissolved gas levels.
Strict global adherence to Tier 2 efficiency standards, pushing for ultra-low no-load loss designs like the S20 series.
For international procurement officers and engineering firms, selecting a transformer manufacturer involves more than just price. At Henan Pirooz Power, we focus on the Total Cost of Ownership (TCO).
We provide complete Type Test Reports from third-party laboratories. Every batch undergoes routine tests including insulation resistance, turns ratio, and impedance voltage tests before shipping.
Understanding the rigors of sea freight, we use vacuum-sealed packaging and reinforced steel frames to ensure our transformers arrive in pristine condition, ready for immediate installation.
A conservator type uses an external tank to allow oil expansion and "breaths" through a moisture-absorber. A hermetically sealed transformer uses corrugated fins that expand to accommodate oil volume without any air contact. Conservator types are typically preferred for larger power capacities (above 2500kVA) and higher voltages.
Yes. As an OEM/ODM specialist, we manufacture transformers for any grid standard, including 11kV/400V, 13.8kV/120V, 33kV/11kV, and more. We also support specialized tap-changer requirements (NLTC or OLTC).
With proper maintenance and regular oil testing, our transformers are designed for a service life of 25 to 35 years.
We provide comprehensive digital installation guides and remote technical video support. For large-scale projects, we can coordinate with local engineering partners for on-site commissioning.
