400 kVA Step Down Oil-Immersed Distribution Transformer For Sale<\/strong><\/h2>\n

The 400 kVA Step Down Oil-Immersed Distribution Transformer<\/a> is designed to deliver reliable medium-to-low voltage power conversion for commercial, industrial, and utility sectors throughout North America and Europe. This 400 kVA oil-filled step-down transformer efficiently converts a primary voltage of 13.8 kV to a standard 480Y\/277 V secondary output, making it ideal for office complexes, manufacturing facilities, residential substations, and renewable energy installations.<\/p>\n

Constructed with premium copper windings and a grain-oriented silicon steel core, the 400 kVA oil-immersed distribution transformer offers low core losses, quiet operation, and superior thermal stability. Its primary winding is configured in Delta, with a grounded Wye secondary, fully compliant with ANSI C57 standards<\/a> and supporting both 50 Hz and 60 Hz power systems.<\/p>\n

Built for durability and longevity, this oil-filled 400 kVA step-down transformer is housed in a sealed tank with corrosion-resistant coating, suitable for both indoor and outdoor applications. The standard ONAN<\/a> (Oil Natural Air Natural) cooling system ensures efficient heat dissipation, with an optional upgrade to ONAF (Oil Natural Air Forced) for high-temperature environments.<\/p>\n

Voltage customization is available for this 400 kVA oil-immersed transformer, including primary inputs of 12.47 kV or 13.2 kV to meet local distribution codes in the US, Canada, UK, Germany, France, the Netherlands, Spain, Italy, and other European markets. Each unit undergoes comprehensive testing\u2014such as vector group verification, temperature rise measurement, dielectric withstand, and load loss testing\u2014to guarantee safety, reliability, and compliance with IEC 60076, IEEE, CSA, UL, and CE certifications.<\/p>\n
