Hitachi 1000 kVA 13.2kV Delta to 480Y/277V Wye Unused Surplus Transformer

Available for sale is one unused surplus Hitachi Energy USA three-phase distribution transformer rated 1000 kVA for 60 Hz service. This unit features a 13,200V delta primary and 480Y/277V wye secondary with ONAN cooling and mineral oil insulation fluid.

The nameplate shows ONAN cooling, mineral oil insulation fluid, 5.64% impedance, and 65°C temperature rise. The transformer is also marked DOE compliant with PCB content below detectable level (<1 ppm). A five-position de-energized high-voltage tap arrangement is provided, offering ±5% adjustment in 2.5% steps around the nominal 13.2 kV primary.

This listing is a strong fit for buyers seeking a modern liquid-filled distribution transformer from a major OEM with standard 480Y/277V secondary service for facility power distribution, plant expansion, infrastructure upgrades, and standby or replacement projects.
