Frequently Asked Questions

What is a distribution transformer?

The final voltage step-down transformer in an electrical power distribution system. It converts medium-voltage utility power (typically 4 kV to 35 kV) down to 120/240 V or 277/480 V. Miami Transformers supplies distribution transformers from 25 kVA through 2500 kVA in padmount and polemount configurations.

What is a padmount transformer?

A ground-level distribution transformer enclosed in a locked steel cabinet mounted on a concrete pad, serving underground electrical systems for residential subdivisions, commercial buildings, shopping centers, and industrial sites.

What are remanufactured transformers?

Used transformers fully disassembled, rebuilt with new components where needed (coils rewound, core repaired, gaskets replaced, tank reconditioned), refilled with reclaimed or new oil, and tested to ANSI/IEEE standards. Miami Transformers' remanufactured units carry a 2-year warranty and cost 50–70% less than new, with 4–6 week delivery instead of 30–50 weeks.

How fast can Miami Transformers deliver?

In-stock remanufactured padmount and polemount units ship nationwide within days. Custom-spec remanufactured units deliver in 4 to 6 weeks. New transformers from OEM manufacturers typically take 30 to 50 weeks.

What kVA range is available?

25 kVA up to 2500 kVA. Common in-stock sizes: 25, 50, 75, 100, 167, 250, 333, 500, 750, 1000, 1500, 2000, and 2500 kVA, in single-phase and three-phase, padmount, polemount, and substation styles.

What certifications does Miami Transformers hold?

ISO 9001 quality management, NETA testing accreditation, NFPA 70E electrical safety, OSHA safety, and EPA environmental compliance for oil and PCB management. Family-owned and operating since 1994.

What payment methods do you accept?

Wire transfer (ACH and domestic wires) for US orders, and wire transfer (T/T) or irrevocable letters of credit (LC) confirmed by a US bank for international orders. We do not accept credit cards.
