Product Overview
The 500 kVA (0.5 MVA) step down distribution transformer from Sichuan Yawei Transformer is designed to provide stable, reliable, and efficient power for industrial plants, commercial buildings, and utility projects worldwide.
It converts medium voltage inputs of 11 kV, 13.8 kV, or 33 kV to low voltage outputs of 400 V, 415 V, or 480 V, making it ideal for factories, shopping complexes, substations, and renewable energy systems.
Available in oil-immersed (ONAN/ONAF) and dry type (cast resin) designs, the transformer is built for durability, high efficiency, and compliance with international standards such as IEC, ANSI, and IEEE. Our factory-direct supply ensures competitive pricing, fast delivery, and full OEM/ODM customization for EPC contractors, distributors, and industrial clients.
