50 KVA power pole transformer single phase pole mounted
distribution 34500V to 120V ANSI IEEE UL certified manufacturers
Powering the grid with confidence, WINLEY's pole mounted
transformers are a top choice for overhead power distribution.
Boasting UL and cUL certifications, they meet strict safety
standards. Fully compliant with ANSI and IEEE requirements, these
transformers shine with high - voltage resistance and strong load -
bearing capabilities.
Built tough with quality materials, they endure harsh outdoor
conditions like extreme weather and temperature swings. Resistant
to corrosion, they reduce maintenance needs. With various models
available, WINLEY's pole mounted transformers offer reliable, safe
power solutions for any scale of demand.

Drawing
The transformer is cylinder sealing structure. Each one is fixed
with grounding devices, hooks, sup porting lugs which conforms to
ANSI standard, and one or two high voltage bushing on the cover,
low voltage bushing on the wall of the tank and eyebolt,connecting
terminals. The tap changer should be adjusted basing on the
instruction after the power off.
