Explore our primary array of high-voltage and medium-voltage sealed oil-immersed and cast resin dry-type distribution transformers designed for extreme conditions.
We operate an advanced production ecosystem spanning computerized cutting, high-precision bending, robotic welding, clean-room assembly, and standard-compliant high-voltage electrical testing. This ensures that every sealed transformer we export operates safely for decades under challenging conditions.
Our key portfolio focuses on 10kV to 35kV oil-immersed power transformers (including energy-saving S11, S13, S14, and S20 series), and fire-resistant dry-type transformers (such as SCB10, SCB11, SCB13, and SCBH15 amorphous alloy series), optimized for power grid networks and industrial applications.
Beyond isolated units, we deliver end-to-end electrical distribution schemes. This includes engineered high/low voltage switchgears, European-style compact package substations, American-style pad-mounted loop feed substations, and dedicated mining/underground distribution hubs.
The global energy transition demands smart, reliable, and eco-friendly distribution architectures. Henan Pirooz Power is driving the future of grid management through several technological fields:
Our oil-immersed systems utilize hermetically sealed designs with corrugated tank elastic expansion or nitrogen cushions. By completely sealing the oil from contact with air and moisture, we eliminate aging of the dielectric oil, drastically cutting lifecycle maintenance overheads and enhancing operating safety.
To support corporate decarbonization goals, we are actively transitioning towards natural and synthetic ester fluids. These eco-friendly alternatives provide high fire points (above 300°C) and excellent biodegradability, lowering environmental risk in sensitive aquatic or metropolitan environments.
Our upcoming generation of high-voltage transformers integrates smart thermal sensors, online dissolved gas analysis (DGA), and winding vibration monitors. These inputs feed directly into edge computing gateways to predict faults before they cause grid downtime.
Our state-of-the-art facility in China guarantees structural integrity, precise electrical windings, and strict quality control through advanced automated machinery.
Our technical engineering team configures every sealed transformer to conform perfectly with local code directives, ecological constraints, and climate profiles.
Our pad-mounted step-up transformers are engineered specifically for renewable energy installations. Designed with high transient overvoltage tolerance, they withstand the fluctuating power cycles typical of utility-scale solar farms and wind parks.
Featuring robust anti-vibration structures, explosion-proof components, and advanced thermal cooling profiles, these hermetically sealed systems are ideal for mining operations, steel plants, and chemical manufacturing plants.
We guarantee compliance with IEC, IEEE, ANSI, and regional European directives. From custom dual-voltage taps to localized seismic ratings, we supply products designed to clear technical inspections smoothly.
