Winley supplies project-specific single-phase pole-mounted transformers for rural utilities, farms, remote properties and cold-climate distribution. These projects can involve higher-voltage overhead feeders, long outdoor distribution routes and substantial 120/240V loads at the point of use.
This 100kVA design supports 35kV-class overhead distribution and ambient temperatures down to -50°C, giving utilities and EPCs a practical option for bringing single-phase service to locations where conventional lower-voltage distribution designs do not cover the project requirement.

-
Farms & Ranches
The 100kVA single-phase capacity can support agricultural properties with several buildings, workshops, pumps or other substantial 120/240V loads.
-
Remote Properties & Facilities
Suitable for remote load points reached by overhead distribution where a local pole-mounted transformer is used to provide low-voltage service.
-
Cold-Climate Distribution
The -50°C operating limit suits outdoor projects where severe winter temperatures form part of the transformer specification.
- External Five-Position Tap Changer: Allows primary voltage adjustment from outside when the transformer is de-energized.
- Double Hanger Brackets: Built for secure pole mounting while keeping the transformer off the ground.
- H1/H2 High-Voltage Bushings: Provide the two primary-side connections required by this 34.5kV configuration.
- X1/X2/X3 4-Hole Spade Terminals: Provide practical connection points for the high-current 120/240V secondary circuit.
- Grounded X2 Neutral: Supports the grounded-neutral arrangement used for the 120/240V secondary service.
- Lightning Arrester Mounting Provisions: Pre-arranged mounting points allow external surge protection to be added when required.
- Automatic Pressure Relief Device: Releases excessive internal pressure to help protect the transformer tank.
- Weather-Resistant Exterior Finish: Coated-steel construction with stainless-steel hardware is configured for permanent outdoor installation.
