1. Winley Electric pole-mounted distribution transformers are UL and cUL Listed under File No. E543292, with ratings from 10 kVA through 500 kVA. They are built to meet or exceed applicable requirements of ANSI/IEEE, CSA, DOE 2016, and IEC 60076 standards.
2. Winley Electric pole-mounted transformers can be flexibly customized to meet project requirements. Customer-specified accessory brands, such as Eaton Cooper Power series and Qualitrol, can also be provided upon request.
3. Winley Electric transformers are supplied to global markets, including North America, South America, and Southeast Asia. Backed by decades of industry experience, we deliver safe, reliable, and efficient transformer designs with comprehensive technical support.
This 25kVA single phase pole mounted transformer is designed for overhead utility distribution systems requiring 14.4kV or 7.2kV primary service to 120/240V low-voltage output. Built as an ONAN oil-filled transformer with CSA C2.2-06 / CSA 802 referenced testing, it is suitable for rural distribution lines, utility service points, small commercial loads, and outdoor single-phase power supply.
Its dual primary voltage configuration allows one transformer design to match common 24.94GrdY/14.4kV and 12.47GrdY/7.2kV distribution networks. For buyers managing feeder extensions, replacement programs, or pole-mounted service upgrades, this helps cover practical utility distribution needs with a compact, field-ready transformer format.
