Henan Pirooz Power Co., Ltd. stands as a titan in the electrical power equipment landscape, a comprehensive manufacturer that harmonizes cutting-edge Research and Development (R&D) with world-class engineering design, precision production, and a global logistics network. As a dedicated Custom OEM Cast Resin Transformer Supplier & Exporter, we specialize in bridging the gap between complex energy needs and reliable hardware execution.
Our operational philosophy is rooted in the E-E-A-T principle: providing firsthand Experience through decades of grid involvement, Expertise via our senior electrical engineering teams, Authoritativeness as a certified Chinese high-tech enterprise, and Trustworthiness by adhering to IEC, ANSI, and GB standards. From 10kV to 35kV oil-immersed power transformers (including the ultra-efficient S20 series) to our signature epoxy resin cast dry-type transformers (SCB series), we provide the vital arteries for modern civilization.
Unlike traditional oil-filled units, Cast Resin Dry-Type Transformers utilize a specialized epoxy resin mixture to encapsulate the windings. This creates a monolithic, moisture-proof, and fire-resistant core that is ideal for sensitive environments.
Our vacuum casting process ensures zero air bubbles in the resin, preventing partial discharge and extending the insulation life to over 30 years.
Cast resin is self-extinguishing. In the event of an external fire, the transformer will not support combustion or release toxic gases, making it mandatory for high-rise buildings.
Zero oil means zero risk of groundwater contamination. These units are 100% recyclable at the end of their lifecycle, aligning with ESG (Environmental, Social, and Governance) goals.
We are constantly pushing the boundaries of Information Gain in energy efficiency. Our technical roadmap highlights the transition from standard silicon steel cores to Amorphous Alloy cores, which reduce no-load losses by up to 70%.
| Feature | SCB10 Series | SCB13/14 Series | SCB18 (Amorphous) |
|---|---|---|---|
| Efficiency Class | Standard | High Efficiency | Ultra-Low Loss |
| Core Material | Cold-Rolled Silicon Steel | High-Permeability Steel | Amorphous Alloy Ribbon |
| Best Application | Industrial Parks | Public Utilities | Green Data Centers |
In cities like London, Dubai, and Singapore, our cast resin units are placed in basement substations of skyscrapers where fire safety is the non-negotiable priority.
Our step-up transformers connect solar farms and wind turbines to the grid, designed to handle the harmonic fluctuations inherent in renewable power generation.
Heavy-duty ZBPW series transformers provide stable input for mining operations and petrochemical plants, where dust and humidity require sealed, resilient equipment.
Being based in Henan, the heart of China's industrial manufacturing hub, gives Pirooz Power a unique advantage in cost-efficiency and logistical speed. Our facility is a modern ecosystem of precision and automation.

Our supply chain resilience is built on vertical integration. We don't just assemble; we control the R&D, the winding logic, and the final electrical testing. This ensures that every unit—whether it's an 800kVA dry-type or a 3000kVA oil-immersed transformer—is a masterpiece of durability.
The energy grid of 2030 will be defined by Smart Manufacturing. Henan Pirooz Power is already integrating IoT sensors into our cast resin units to monitor temperature, humidity, and load in real-time. This predictive maintenance capability reduces downtime and total cost of ownership (TCO) for our global partners.
We provide full documentation and compliance support for regional markets, including:
A: The primary advantage is safety and placement flexibility. Cast resin transformers are fire-resistant and environmentally friendly, allowing them to be installed inside buildings, hospitals, and underground stations where oil-filled units are prohibited due to fire and leakage risks.
A: Yes. We specialize in custom voltage ratios, specific vector groups (like Dyn11 or Yyn0), and specialized cooling systems (AN/AF). Our engineers can design equipment tailored to the unique grid requirements of any country.
A: We use premium F-class or H-class insulation materials and perform vacuum pressure impregnation (VPI) or vacuum casting to ensure the resin is completely homogenous, protecting the coils from moisture and chemical contaminants.
A: Depending on the complexity and KVA rating, lead times typically range from 4 to 8 weeks. Our efficient Henan supply chain allows us to maintain faster turnaround times than many European or North American manufacturers.
