Explore our core industrial transformer lineup, featuring high-efficiency configurations, standard compliance, and rugged designs engineered for harsh electrical environments.
Navigating the transition toward high-reliability, fire-safe, and environmentally conscious power distribution architectures.
In modern industrial and commercial energy systems, electrical safety, thermal stability, and low environmental impact have transitioned from operational preferences to strict global regulatory mandates. Henan Pirooz Power Co., Ltd. stands as a premier globally recognized manufacturer integrating research and development, engineering design, precision production, sales, and complex system after-sales services. Our expertise delivers highly customized, reliable, and energy-efficient electrical solutions optimized for grid infrastructure projects, offshore wind energy farms, marine applications, data centers, and heavy processing facilities.
Pirooz Power designs and manufactures an extensive portfolio of MV/HV power assets. Our core product range covers 10kV to 35kV oil-immersed power transformers (including the ultra-efficient S11, S13, S14, and S20 series) and high-performance dry-type transformers (SCB10, SCB11, SCB13, and the low-loss amorphous alloy SCBH15 series). Furthermore, we design custom-engineered tap-changing, rectifier, and furnace transformers to survive highly challenging electrical duties.
Vacuum Pressure Impregnated (VPI) dry-type transformers represent a critical design paradigm shift. Unlike traditional Cast Resin (CR) dry-type systems, which encapsulate the coils in a solid block of epoxy resin, VPI technology uses a polyester or silicone resin coating applied under cycles of intense vacuum and high pressure. This technique forces the insulating varnish to deeply penetrate the microscopic voids within the conductor windings.
This mechanical impregnation yields outstanding advantages:
Our manufacturing facilities feature fully automated winding, vacuum chambers, and precision CNC core cutters. We guarantee compliance with international standards, delivering minimum partial discharge (<10pC) and lower load losses than the industry average.
Witness our complete vertical manufacturing capability, from laser steel cutting to automated testing stages.
The manufacturing center of Henan Pirooz Power Co., Ltd. utilizes state-of-the-art tooling lines to ensure precise control over electromagnetic tolerances. Our production flow follows a rigorous quality gates protocol, including precision laser cutting of silicon steel sheets, computerized copper winding alignment, high-vacuum chamber pressure cycles, and automated spray coating lines. Our facilities are designed to eliminate moisture and microscopic air pockets, the two primary causes of partial discharge in high-voltage environments.
How VPI dry-type transformers are shaping energy distribution grids on every continent.
Densely populated municipal grids, subway networks, and commercial high-rises enforce strict fire-safety regulations (such as NFPA and regional European directives). Because our VPI transformers avoid flammable fluids, they reduce the footprint, ventilation, and expensive fire-suppression equipment required in urban substations.
In chemical plants, oil refineries, mining sites, and steel mills, environmental pollution (e.g., coal dust, saline air, gaseous corrosive chemicals) represents a severe threat to electrical equipment. Our custom VPI varnishing processes shield the copper windings from environmental ingress while providing superior cooling under persistent overloads.
Hyperscale data centers require highly stable step-down transformers capable of managing substantial non-linear harmonic currents generated by thousands of IT servers. Pirooz VPI systems utilize custom-wound K-factor-compliant geometries to prevent transformer overheating and harmonic losses.
As energy efficiency requirements increase worldwide (such as the EU Ecodesign Directive and US DOE standards), our technical roadmap emphasizes the integration of amorphous alloy cores (featured in our SCBH15, SCBH17, and SCBH19 series). By utilizing a non-crystalline magnetic structure, no-load core losses are reduced by up to 70% to 80% compared to traditional silicon steel.
Furthermore, we are integrating IoT diagnostic interfaces into our OEM custom lineups. These sensors monitor winding temperatures, insulation resistance, and mechanical vibration patterns in real time. This system alerts maintenance teams to thermal anomalies or partial discharge signs, shifting operations from reactive maintenance to automated predictive care.
Integrated electrical packaging designed to operate under diverse regulatory environments.
Pirooz Power provides complete, integrated electrical systems to streamline procurement and construction. These systems include high and low voltage switchgear, European-style compact substations, American-style pad-mounted substations, and underground distribution substations. We coordinate design files, thermal layouts, busbar routing, and protective relay settings to reduce project timelines and ensure single-source engineering accountability.
