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