UL Certified Single Phase Pad Mounted Transformer for North American Distribution

Compact & Efficient Distribution Solution
Designed for ground‑level pad mounting, this transformer seamlessly integrates with underground cable networks, eliminating unsightly overhead lines while providing reliable power to residential communities, commercial outlets, and rural areas.

UL Certified for North American Market
Fully compliant with UL and cUL North American safety standards, ensuring smooth customs clearance and utility acceptance across the United States and Canada.

Wide Capacity & Voltage Range
Available from 15kVA to 250kVA, with primary voltages up to 34.5kV and secondary voltages 120‑240V or 240‑480V, flexibly addressing power demands ranging from single‑family homes to small commercial complexes.

Modular Compartmentalized Layout
Adopts a modular compartmentalized design that balances electrical safety, ease of operation and maintenance, and space utilization. The oil tank houses high‑voltage and low‑voltage cable terminal compartments cleverly arranged side by side, suitable for long‑term stable operation under complex outdoor conditions.

Removable Flip‑Top Cover for Easy Maintenance
The cover opens fully 180°, providing unobstructed top visibility and operating space. Stainless steel hinge pins ensure robust, durable, and corrosion‑resistant performance, guaranteeing smooth opening and closing even after years of use. This design greatly facilitates internal wiring inspection, bushing maintenance, and troubleshooting.

Flexible Network Connectivity
Equipped with external clamping high‑voltage bushing wells, supporting both loop feed and radial feed as mainstream wiring methods. This design enhances the flexibility and reliability of grid connections, facilitating the expansion and reconfiguration of distribution networks.

Low Maintenance & High Efficiency
Advanced core construction using high‑grade grain‑oriented silicon steel delivers extremely high efficiency with minimal heat generation. Mineral oil insulation and cooling ensure efficient operation even under harsh conditions.

Energy Savings & Environmental Benefits
Higher efficiency extends transformer lifespan and delivers significant cost savings through reduced energy bills and lower total ownership cost.

Weather‑Resistant Construction
Weather‑resistant enclosure with advanced coating technology withstands rain, sleet, snow, and external ice formation, ensuring reliable outdoor service for decades.
