Single-Phase 25–167 kVA · Three-Phase 75–2500 kVA
Miami Transformers is a nationwide padmount transformer supplier with rotating in-stock inventory ready to ship. Dead-front and live-front configurations, all standard utility primary voltages (4160 V through 34.5 kV) and secondaries (120/240 V, 208Y/120 V, 480Y/277 V). Remanufactured to ANSI standards with a 2-year warranty.
What Is a Padmount Transformer?
A padmount transformer is a ground-level distribution transformer housed in a locked, tamper-resistant steel cabinet and mounted on a concrete pad. Unlike pole-mounted transformers used on overhead lines, padmount transformers serve underground electrical distribution — the standard for modern subdivisions, commercial properties, shopping centers, hospitals, schools, data centers, and industrial sites.
Padmount units step medium-voltage utility primary (4 kV to 35 kV) down to the secondary voltages used by buildings (120/240 V single-phase or 208Y/120 V, 240/480 V, 480Y/277 V three-phase). All Miami Transformers padmounts ship remanufactured, tested to ANSI/IEEE standards, and carry a 2-year warranty.
Single-Phase & Three-Phase Padmount Transformers
