Intro
A loop feed padmount transformer is designed for underground power distribution where reliability matters. Unlike a radial feed, it uses two primary cable entries forming a loop, allowing power to be rerouted if a fault occurs.
How It Works
Power enters via one set of bushings, passes through the transformer, and exits to the next unit. When a fault happens, the loop can be opened at the defective section – the rest of the network stays live.
Main Advantages
- High reliability – minimal outage area
- Faster restoration – isolate fault without shutting down the whole line
- Safe & compact – tamper-proof, ground-level enclosure
- Easy expansion – add more transformers without redesign
- Low maintenance – sealed compartments, no exposed live parts
Typical Applications
- Commercial complexes & office parks
- Industrial plants
- Residential subdivisions with underground cabling
- Solar farms & wind power connections
- Data centers & critical infrastructure
