Description

50kVA Single Phase Pole Mounted Transformer 43800V To 120/240V ANSI/IEEE Standards


The Winley Electric 50 kVA Single-Phase Pole-Mounted Transformer is engineered for high-reliability utility and residential power distribution. Designed specifically for the North American market, this conventional-type liquid-filled unit combines robust construction with strict adherence to ANSI/IEEE safety and efficiency standards, fully compliant with DOE 2016 requirements.

Featuring a 43800V primary to 120/240V secondary dual-winding design, 5-position de-energized tap changer, and ONAN self-cooling, this transformer delivers stable voltage regulation and long-term durability in demanding outdoor overhead environments. Its copper/aluminum-compatible bushings, subtractive polarity, and non-PCB mineral oil insulation ensure superior thermal performance, corrosion resistance, and operational safety for pole-mounted distribution applications.

50 KVA Single Phase Pole Mounted Transformer 43800V To 120/240V ANSI/IEEE Standards Electric Pole Transformer


Key Feature

1.50kVA High Capacity and Wide Voltage Range:

Steps down 43800V high primary voltage to 120/240V secondary voltage, catering to overhead utility and remote load distribution needs.


2.ANSI/IEEE and DOE 2016 Compliance:

Fully meets ANSI/IEEE C57 standards, DOE 2016 efficiency requirements, ensuring safety and performance validation for the North American market.


3.Robust Overhead Design:

Conventional-type liquid-filled construction with a compact, pole-mounted form factor; engineered to withstand harsh outdoor weather conditions.


4.Efficient Self-Cooling System:

Equipped with ONAN (Oil Natural-Air Natural) self-cooling, eliminating the need for external fans and reducing maintenance costs.


5.Precise Voltage Regulation:

Integrated with a 5-position de-energized tap changer (2.5% tap range) for accurate voltage adjustment, optimizing performance for varying load conditions.


6.Superior Insulation and Safety:

Features non-PCB mineral oil insulation (high fire point) and Class E insulation rating, ensuring excellent thermal stability and operational safety.


7.High-Quality Construction:

Copper windings, corrosion-resistant tank, and weatherproof epoxy coating guarantee long-term reliability and durability in overhead environments.


8.Subtractive Polarity and Flexible Termination:

Designed with subtractive polarity for easy integration into standard utility grids; compatible with both aluminum and copper conductor connections.



Applications


1.Residential and Community Development:Supplying clean, stable power to suburban neighborhoods, housing complexes, and remote residential areas where overhead lines are the primary distribution method.


2.Agricultural and Rural Facilities:Powering farms, ranches, irrigation systems, and rural light industrial facilities, where transformers must withstand extreme weather conditions and low-maintenance requirements.


3.Utility and Municipal Infrastructure:Serving as a critical step-down solution for public utility grids, city street lighting, municipal parks, and community centers, complying with ANSI/IEEE and local electrical codes.


4.Remote Industrial Loads:Supplying power to small manufacturing facilities, construction sites, mining operations, and off-grid industrial locations where a compact, weatherproof overhead solution is essential.


5.Resort and Recreational Areas:Ideal for campgrounds, golf courses, marinas, and outdoor recreational facilities, providing reliable power infrastructure in open, exposed environments.
