50Kva Single Phase Pad Mounted Transformer Distribution Oil
Immersed 22860V to 240V Residential
Single-phase padmount transformers designed to bring underground
1-phase power to homes, and commercial buildings from utility
feeds. These units are perfect for urban public locations due to
their tamper-proof and low profile design.
