Rectifier transformer is a dedicated special power transformer designed to match silicon rectifier or thyristor rectifier equipment, converting alternating current into stable direct current for industrial production. Unlike conventional distribution transformers for power grid distribution, rectifier transformers operate under serious harmonic interference, uneven load current and frequent surge current caused by rectifier circuit commutation. Its core design targets anti-harmonic performance, low output voltage ripple, strong overload resistance and stable long-running performance under non-sinusoidal working conditions, complying with IEC60076, GB/T10226 and related international industrial equipment standards. Jiangsu Tianhua specializes in full-series rectifier transformer R&D and production with decades of export experience, supplying both oil-immersed and dry-type structures to global industrial clients across metallurgy, chemical, electroplating, new material electrolysis, wastewater treatment and mining industries.
The product capacity range covers dozens of kVA up to tens of thousands of kVA. Input high voltage options include 6kV,10kV,33kV,35kV, while secondary windings adopt multi-group split winding design commonly used for 6-pulse,12-pulse,24-pulse rectifier systems. More pulse numbers can effectively restrain input-side harmonic current and reduce power grid pollution, which becomes the mainstream configuration for large electrolysis and smelting projects. Cooling solutions include ONAN natural oil cooling, ONAF forced air cooling for oil type and AN/AF air cooling for dry type, selected based on site ambient temperature, installation environment and client’s equipment layout requirement.
In recent years, global industrial upgrading accelerates the demand of high-performance rectifier equipment. Aluminium electrolysis, copper refining, rare earth electrolysis and new energy raw material production keep expanding in emerging markets of Southeast Asia, Middle East, Africa and Latin America, continuously boosting the order demand of customized rectifier transformers. Our factory supports full non-standard customization on rated capacity, input & output voltage, winding group number, pulse mode and installation dimension according to customers’ rectifier cabinet parameters and on-site workshop layout. Every finished rectifier transformer passes complete routine test, partial discharge test, harmonic simulation test and temperature rise test before leaving factory to eliminate potential hidden faults during continuous industrial production.
