Frequently Asked Questions
What is a padmount transformer?
A padmount transformer is a ground-level, enclosed transformer used in underground electric power distribution. It sits on a concrete pad and features a locked steel cabinet for safety and tamper resistance.
What sizes of padmount transformers are available?
Fluxco offers padmount transformers from 75 kVA to 10,000 kVA (10 MVA) in both single-phase and three-phase configurations to meet various load requirements.
Are your padmount transformers DOE compliant?
Yes, all our padmount transformers meet or exceed DOE 2016 efficiency standards (10 CFR 431). We can provide efficiency documentation and compliance certificates.
Where are Fluxco's padmount transformers sourced?
Fluxco draws on a vetted network of 150+ manufacturers worldwide, matching each order to the supplier best suited to your specs, voltage class, and compliance needs. Every unit meets IEEE C57.12.00 and DOE 10 CFR 431 standards. For projects claiming clean-energy tax credits, we can prioritize US-made units and provide the domestic-content and FEOC documentation you need to qualify.
