Product Overview
This 2000/2667kVA dual-rating three phase VPI dry type transformer is configured for 6900V to 480Y/277V power distribution systems. Built with copper windings, AN/AF cooling, Dyn11 connection, and a NEMA 3R coated steel enclosure, it is suitable for outdoor pad mount or floor mount installations where an oil-free transformer design is preferred. The transformer complies with DOE 2016 and ANSI C57.12.01 requirements for North American project use.
The dual-rating design allows the transformer to operate at 2000kVA with natural air cooling and up to 2667kVA with forced air cooling. This makes it practical for building service entrances, facility distribution points, data center support areas, and industrial sites where load growth or extra cooling capacity may be required.

Commercial Buildings
Suitable for commercial facilities requiring 6900V to 480Y/277V power distribution, such as building service entrances, HVAC systems, lighting panels and low-voltage switchgear.
Light Industrial Facilities
The 2/2.667 MVA AN/AF capacity supports plant distribution, workshop power supply, production equipment and auxiliary facility loads where both normal load and peak demand need to be considered.
Outdoor Electrical Rooms
With a NEMA 3R pad/floor mount enclosure, the transformer is suitable for outdoor or semi-outdoor electrical rooms where oil-free dry type equipment is preferred.
Facility Power Distribution Systems
The 480Y/277V secondary output can supply common North American facility loads, including lighting, HVAC, panels, motors and downstream distribution equipment.
Data Center and Critical Facility Support
LV winding temperature sensors, fan control, alarm and trip contacts make the transformer suitable for controlled power environments where thermal monitoring and load stability are important.
Campus and Infrastructure Projects
Suitable for campus buildings, public facilities and infrastructure power rooms requiring medium-voltage step-down to 480Y/277V distribution.
