All Bardeen’s pad-mounted transformers meet the latest ANSI/IEEE, DOE, and CSA standards.
Rated up to 34.5 kV and 10,000 kVA (ONAN cooling), they provide underground distribution power for commercial, industrial, and utility applications.
Engineered for outdoor concrete pad mounting, with sealed HV and LV compartments for maximum safety.
Customize from Our Standard Product Line
If you spot a near-match in our catalog, we can quickly modify our standard transformers for your application. Adjustments cover capacity, voltage class, cooling type and installation structure.
Build per Your Technical Documents
Send us your specifications or drawings. Our engineering team reviews the design, validates all key parameters with you, and manufactures strictly in accordance with international standards.
