Three Phase Pad Mount Transformers

OMEX Pad Mount Transformers are constructed to the highest quality standards. We design and manufacture our transformers as per ANSI, IEEE, DOE and UL Standards (as applicable).

We can also provide UL Transformers as requested. We have capabilities to produce any custom product up to 10,000 VA. We can also provide reconditioned transformers for budgetary projects.

OMEX tamper-proof, compartmentalized, liquid-filled, pad-mounted (or padmount for short) transformers are all-in-one units designed, built, and tested in accordance with the highest industry standards and can be customized with over-current protection, and sectionalized switching to give you maximum control over your distribution system.
