Padmount
Transformers
Tamper-resistant, compartmentalized liquid-filled padmount transformers for single-phase and three-phase underground cable systems. Rated from 10 kVA to 2,500 kVA at primary voltages from 2.4 kV to 34.5 kV.
Compact, Secure
Underground Power
Padmount transformers serve as the final voltage step-down stage in underground distribution systems, converting medium-voltage supply to the utilization voltage required by residential, commercial, and industrial loads. Their tamper-resistant enclosures and locked compartments make them the standard choice wherever public access is a concern.
Candron padmount transformers are built to ANSI C57.12.25 (single-phase) and ANSI C57.12.26 (three-phase) with CSA certification for Canadian installations. Standard features include radial or loop configurations, integral overcurrent protection options, and oil-immersed construction for thermal efficiency and long service life.
Both single-phase and three-phase configurations are available with customized tank dimensions, high-voltage arrangements (radial, loop, or multi-tap), low-voltage termination options, and a range of protective accessories.
Select Your Padmount Type
Three-phase liquid-filled padmount transformers for commercial, industrial, and utility underground distribution networks.
Single-phase padmount units for residential subdivision loops, streetlighting, and light commercial underground distribution.
Where Padmounts Are Used
Step down utility distribution voltage to 120/240 V for single-family and multi-unit residential developments with underground services.
Supply three-phase power to shopping centres, office buildings, and mixed-use developments from underground distribution feeders.
Connect plant equipment to the utility distribution system where overhead lines are restricted or aesthetics require underground routing.
Step up generation voltage for interconnection to the utility distribution network in ground-mount and rooftop solar installations.
Provide reliable, efficient primary power transformation with low-loss designs and custom secondary voltage arrangements for critical facilities.
Power transit stations, EV charging infrastructure, and public facilities from underground utility distribution loops.
