Substation Transformer
Heavy-duty units built for demanding applications in non-public areas.
Capabilities
These ruggedized transformers are ideal for substation yards and power distribution line-ups.
Product Details
Rucker liquid-filled distribution substation, and power-class substation transformers are designed, built, and tested in accordance with the highest industry standards including NEMA, ANSI C.57, DOE, and IEEE as applicable. With a range of customizable features, Rucker substations can be configured to maximize performance, minimize potential arc flash exposure, and address environmental concerns. All designs can be supplied with full, or partial length air terminal chambers to make installation easy.
