10Kva Single Phase Pole Mounted Transformer 12.47KV To 120V Power Distribution Transformer UL Listed
A compact, reliable single‑phase pole‑mount distribution transformer designed for utility and commercial applications. Built to meet ANSI/IEEE standards, it provides dependable 120/240 V secondary service from a 7200/12470Y grounded‑wye primary and is optimized for low‑loss, long‑term operation.
Performance & Design: High‑efficiency copper windings with a grain‑oriented steel core and mineral‑oil (ONAN) cooling deliver stable thermal and electrical performance with low no‑load and load losses.
The transformer’s coated steel enclosure with corrosion‑resistant details, porcelain high‑voltage bushings and tin‑plated terminals, together with grounding and lightning‑arrestor provisions, simplifies installation and maintenance, while pole‑mount hanger brackets, lifting lugs, a fill valve and removable access covers ensure straightforward field handling and servicing.
WINLEY’s pole‑mount transformers are UL/cUL certified and available in rated capacities from 10 kVA to 333 kVA. Our products meet or exceed major international standards, including ANSI, IEEE, CSA, and IEC 60076. With extensive experience in pole‑mount transformer design and manufacture, WINLEY provides comprehensive technical support and after‑sales service.
