UL/cUL Certifications Supplier 25Kva Single Phase Pad Mounted
Transformers for Power Distribution 4160V To 120V
WINLEY’s single-phase pad-mounted transformers are reliable outdoor
power solutions designed for residential, commercial, and light
industrial use. Built with weather-resistant enclosures mounted on
concrete pads, they efficiently step down high-voltage utility
power to low-voltage outputs (ranging from 15 to 333 kVA),
featuring robust components like high-voltage bushings, fuses, and
load-break switches for secure operation.
UL-certified and compliant with ANSI/IEEE standards, these
transformers ensure safety, efficiency, and adherence to strict
industry regulations.Engineered for durability and long lifespan,
WINLEY’s transformers deliver stable performance, low noise, and
consistent energy distribution, making them ideal for urban and
suburban applications.
