Customized Special Purpose Transformers For Industrial, Mining And Railway Power Supply Needs
Yulan Transformer designs and manufactures special purpose transformers engineered for specific industrial processes where standard power transformers cannot meet the electrical, thermal, or mechanical demands. Our special purpose transformer portfolio includes furnace transformers, rectifier transformers, and custom-engineered units for steel mills, metallurgy plants, electrochemical facilities, and power electronics systems.
Furnace transformers are designed for electric arc furnace (EAF) and ladle furnace (LF) applications in the steel industry. These units feature high secondary current, low secondary voltage, and robust construction to withstand the cyclic thermal and mechanical stresses of arc furnace operation. Typical ratings range from 5 MVA to 120 MVA, with secondary voltages from 100V to 1,500V.
Rectifier transformers supply power to rectifier systems in electrochemical processes, DC arc furnaces, and variable speed drive (VSD) applications. These transformers are designed with phase-shift windings to reduce harmonic distortion, and with multiple secondary windings for 6-pulse, 12-pulse, or 24-pulse rectifier configurations. They are commonly deployed in aluminum smelting, chlor-alkali production, and large DC power supply systems.
Custom special purpose transformers we manufacture include: earthing/grounding transformers, traction transformers for railway electrification, induction heating transformers, and voltage regulator transformers. Each unit is custom-designed to project specifications, including impedance, harmonic withstand capability, and cooling requirements.
All special purpose transformers are manufactured using the same production infrastructure as our power transformers — 400kW KVPD drying systems, computer-controlled winding machines, and 1200kV impulse test capability — ensuring consistent quality across all product lines. For reactive power compensation in furnace and rectifier installations, we also supply magnetically controlled reactors.
