Certificate Collection

1400 MVA, 1500 MVA, and 2000 MVA ultra high power transformers are designed for national grid, power generation, and ultra-high-voltage transmission systems. Built with advanced copper or aluminum windings, they provide excellent mechanical strength, low loss, and high efficiency under extreme load conditions. Featuring enhanced insulation systems, efficient oil or forced-air cooling, and precise voltage regulation, these transformers ensure long-term stability and reliability. They are fully compliant with IEC 60076 standards and suitable for 400 kV to 800 kV grid applications.

Applications:

The 1400 MVA to 2000 MVA ultra high power transformers are primarily used in large-scale power generation plants, national grid interconnection systems, and ultra-high-voltage (UHV) transmission networks. They are ideal for 400 kV–800 kV substations, hydroelectric and thermal power stations, as well as major industrial zones requiring high-capacity and stable energy transmission. These transformers play a key role in reducing transmission losses, stabilizing voltage, and ensuring reliable long-distance power supply across regions.

All products carry CE/IEC/SGS/BV/GOST certifications. Our $8M R&D center develops next-gen solutions.Our air natural cooling transformer series represents the pinnacle of power conversion technology, delivering unmatched performance, safety, and durability. Engineered for excellence, these transformers set industry benchmarks for reliability across global power applications.
