  • ABB

    ABB manufactures liquid-filled substation ANSI transformers, substation non-auto transformers, and substation secondary unit ANSI transformers. The substation ANSI transformers are step down distribution transformers and feature 750 kVA through 20 MVA, with primary voltages through 69 kV. The substation non-auto transformers are step down power transformers for network application when separate grounding systems between the high voltage and low voltage is required. These transformers feature rating up to 1300 MVA. The substation secondary unit ANSI transformers features 112.5 kVA-20MV, primary voltages through 69 k, and are typically close coupled to switchgear, motor control, bus duct, or other incoming and outgoing equipment.

  • Cooper Power Systems

    Cooper Power Systems offers primary or secondary open substation transformers with cover-mounted bushings, or primary and secondary unit substation transformers with enclosed sidewall-mounted bushings for connections to switchgear. The substation transformers are available as unit, open of VFI types,  and meet IEEE, ANSI, CSA/CEA, and NEMA standards.

  • Eaton Corp.

    Eaton Corporation manufactures primary and secondary unit substation transformers that feature 112.5 kVA through 3750 kVA; and low voltages of 208V, 240V, 480V, or 600V. The company's substation transformers can be indoor or outdoor, and are available with a selection of high-voltage incoming sections.

  • GE

    GE Industrial manufactures two types of secondary substation transformers: liquid filled, and ventilated dry-type.
