2500Kva Three Phase Pad Mounted Transformer step down 12470V to
400V
summary
WINLEY offers a complete line of liquid-filled ThreePhase
Pad-Mounted distribution transformers that meet applicable
ANSI®/IEEE® standards.With high voltages up to 34.5 kV and ratings
up to 5,000 kVA, It is suitable for high-voltage and large-capacity
occasions, such as power substations, industrial power consumption,
etc. In high-load, high-voltage scenarios, oil-immersed
transformers have better performance and stability.
