FAQ

Common questions

What is the lead time on MV pad-mounted transformers?

24–36 weeks from PO confirmation. Longer lead times apply to higher voltage classes and custom configurations.

What fluid options are available?

Mineral oil and FR3 (less-flammable fluid) are both available. Specify FR3 if the installation requires reduced fire risk or if local code requires it.

Do you support loop-feed and radial-feed configurations?

Yes. Both loop-feed (two-bushing primary) and radial-feed (one-bushing primary) are available. Specify your utility's required configuration at quote.

Are MV units UL listed?

Yes. All pad-mounted units are UL/cUL listed. IEEE C57.12.26 and C57.12.28 compliant. File number provided on request.

What warranty applies to pad-mounted transformers?

5 years from date of shipment covering windings, core, tank, and terminals. Full terms in our Terms & Conditions of Sale.

Beyond transformers

Transformers are our main focus, but we are able to source other electrical equipment to fulfill project needs. Among these include motors, generators, and various types of switchgear. Sourced through the same supply channels, one PO, and the same point of contact ensures consistency and reliability across the board.
