PMT - Pad Mounted Transformers
Our pad-mounted transformers are engineered to handle power capacities ranging from 500 kVA to 10,000 kVA, effectively stepping down high primary voltages to lower secondary voltages suitable for utility customers.
PMT - Pad Mounted Transformers
TMR Transformers manufactures pad-mounted transformers (PMT) — compact, ground-level distribution units housed in a tamper-resistant, locked steel enclosure and mounted on a concrete pad. With no exposed live parts, they can be installed safely in public and pedestrian areas without a fenced substation or elevated platform.
We build pad-mounted transformers for capacities from 500 kVA to 10,000 kVA with primary voltages up to 33 kV, in three-phase, oil-immersed configurations at 50 Hz or 60 Hz. The fully sealed, dead-front design gives maintenance-free, weatherproof operation and steps high primary voltage down to the secondary levels required by utility and industrial customers, all within a compact footprint.
Pad-mounted transformers are ideal for urban and residential distribution, commercial developments, campuses, and rural or space-constrained sites. As a direct manufacturer TMR can configure ratings, bushings and enclosure options to your specification. Request a quote for a pad-mounted transformer suited to your network.

Frequently asked questions
- What is a pad-mounted transformer?
- A pad-mounted transformer is a ground-level distribution transformer housed in a locked, tamper-resistant steel enclosure on a concrete pad. Because it has no exposed live parts, it can be installed safely in public areas without a fenced substation.
- What is the difference between a pad-mounted and a pole-mounted transformer?
- A pad-mounted transformer sits at ground level in a sealed cabinet and suits underground distribution networks, while a pole-mounted transformer is fixed on an overhead pole for overhead lines. Pad-mounted units are safer in populated areas and blend into the streetscape.
- What capacity pad-mounted transformers does TMR manufacture?
- TMR manufactures pad-mounted transformers from 500 kVA to 10,000 kVA with primary voltages up to 33 kV, in three-phase oil-immersed configurations at 50 Hz or 60 Hz, configured to your network requirements.
- Are pad-mounted transformers safe and maintenance-free?
- Yes. The fully sealed, dead-front design keeps all energised parts enclosed and locked away, and the weatherproof construction gives largely maintenance-free operation, making it well suited to urban and residential sites.
