Product Details
10kva Single Phase Pole Mounted Distribution Transformer 12.47KV To
120V ANSI IEEE Standards UL Listed
Winley’s 10 kVA Pole-Mount Distribution Transformer, engineered for
reliable single‑phase service on overhead distribution systems.
This compact, ANSI‑compliant unit is designed for durable outdoor
use and optimized for efficient, long-term performance.
This transformer combines proven design with high efficiency and
field‑friendly features—externally accessible tap changer, robust
bushing insulation, and flexible terminal options—making it an
excellent choice for residential and light commercial distribution
on overhead lines. Most importantly, its UL/cUL certification
ensures it meets stringent safety and performance standards for
North American utilities and contractors.
