Engineered transformer solutions from 630 kVA distribution units to ultra-high-power electric furnace transformers — designed and tested to ANSI, IEEE, and IEC standards.
Full series 13.2 kV–230 kV oil-immersed and dry-type distribution and step-up power transformers for utility, industrial, and renewable applications.
Complete ultra-high-power EAF transformer packages engineered for full melting and refining working conditions. Our 140,000 kVA unit is the largest single-unit capacity electric furnace transformer built in China, and the third-largest capacity electric furnace transformer in the world.
Submerged-arc furnace transformers built to the JB/T 8506 “Yellow Phosphorus Furnace Transformer” national standard, a standard our engineering team helped author. Capacity up to 350,000 kVA with fully customized secondary output for continuous furnace operation.
Special submerged-arc furnace transformers engineered for calcium carbide production, built to the JB/T 6303 “Calcium Carbide Furnace Transformer” national standard. Heavy-duty design for continuous, high-current operation in demanding furnace environments.
Rounding out our product range with reactive and rectification equipment for utility and industrial applications.
Up to 220 kV, for reactive power compensation and voltage regulation on long transmission lines.
Up to 330 kV, engineered for electrolytic, traction, and industrial DC-conversion applications.
On-load and off-circuit tap changers, forced-air and forced-oil cooling systems, sized to application.
Bushings, gas relays, temperature and oil-level monitoring, and digital condition-monitoring packages.
