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.

Advantages of Pole-mounted Transformers
1.Cost-effective:The installation of pole mounted transformer is less expensive
than the construction of pad mounted systems.These types of systems
are frequently the most cost-effective choice available.
2.Reliability :In terms of maintenance and repair, pole mounted transformers are
easy to maintain and examine.As a result, they are an alternative
for the distribution of power to the general population and are
generally considered to be more dependable.
3.Flexibility:A pole mounted transformer can adapt to the ever-changing
electrical requirements of communities because of the modular
nature of its design.
4.Safety :Pole-mounted transformers are generally designed with safety
standards before mounting on a pole. Engineers follow a certain
safety requirements to reduce the risk of electrical shocks.
5.Compatibility :The use of pole-mounted transformers is an ideal option since it
is extremely flexible. These units are compatible with electrical
grids and concrete woods, making the distribution of power easy and
smooth.
