Liquid Filled Transformers

Substation
Square D three-phase, substation liquid-filled transformers are used in a wide variety of commercial and industrial applications. These units are designed to meet all applicable industry standards of ANSI, NEMA, CSA and IEEE and are available with mineral oil for outdoor use or high-fire point fluids for indoor use.

Construction allows for stand-alone installation using terminal compartments or close-coupled to primary and secondary switchgear providing a complete substation line-up.

Available in primary voltages from 2.4 kV to 69 kV in 225 through 20,000 kVA sizes, 600 volt through 35 kV secondary voltage ratings are available.
