10.4 MVA dry-type rectifier transformer is a high-capacity transformer designed to supply rectifier or converter systems that transform AC power into DC power. Unlike oil-immersed rectifier transformers, this VPI dry-type design uses vacuum pressure impregnation insulation and contains no liquid dielectric.
Varelen's 10.4 MVA rectifier transformer is designed with copper windings, Class H insulation, phase-shift capability and four voltage outputs. The configuration can be adapted to the electrical requirements of high-power rectifier systems.
The transformer is suitable for applications including electrolysis, electrometallurgy, railway transit and industrial drives, where high reliability, thermal performance and resistance to harmonic effects are important.
The transformer can be engineered according to project requirements for voltage ratio, phase-shift angle, output configuration, cooling method, impedance, insulation level and installation environment.
10mva dry type converter transformer is one of the biggest dry type rectifier transformer on the world, which weight is up to 25 tons.

Sustainable, Its design and operation is considerate of the environment through:
• A long service life of 20+ years,
• Its low loss levels; meaning it uses less electricity, and • 90% recyclable transformer materials; meaning less waste.
This high-capacity dry rectifier transformer is suitable for electrolysis, electrometallurgy, rail transit, industrial drive and other high-demand applications, taking into account safety, reliability and efficiency.
Varelen developed its 10.4 MVA dry-type rectifier transformer technology in 2019 and has continued to develop high-capacity converter and railway traction transformer solutions.
Varelen manufactures both VPI and cast resin dry-type transformers, allowing the insulation technology to be selected according to the application and project requirements.
Voltage ratio, phase-shift configuration, number of secondary windings, impedance, cooling system and insulation requirements can be engineered according to the converter or rectifier system.
Transformer testing can include winding resistance, voltage ratio and phase displacement, short-circuit impedance, load loss, no-load loss, AC withstand tests and partial discharge measurements according to the applicable project standard.
A rectifier transformer is specifically designed to work with rectifier or converter equipment. Its winding configuration, phase displacement, impedance and thermal design are coordinated with the rectifier system and its harmonic currents.
VPI dry-type converter transformer contains no liquid dielectric, eliminating oil leakage and reducing fire-related risks. It can be suitable for indoor industrial installations where environmental and fire-safety requirements are important.
Yes. The transformer can be engineered according to the required HV/LV voltage, phase-shift angle, number of outputs, pulse configuration, impedance, cooling system, insulation level and installation conditions.
