UL certified 3750 kVA Three Phase Pad Mounted Distribution Transformer 12470V To 480V ANSI IEEE DOE 2016 Standards

UL/cUL Certified 3750 kVA Three Phase Pad Mounted Distribution Transformer 12470V To 480V ANSI IEEE DOE 2016 Standards

WINLEY offers a complete line of liquid-filled three phase pad mounted transformers that meet applicable ANSI®/IEEE® standards and has obtained UL/cUL certification.With high voltages up to 34.5 kV and ratings up to 5,000 kVA, It is suitable for high-voltage and large-capacity occasions, such as power substations, industrial power consumption, etc. In high-load, high-voltage scenarios, oil-immersed transformers have better performance and stability.

Main data

Technical drawings

The Pad-Mounted Transformer features a compartmental-type design with a lift-up hood, housed in a NEMA 3R-rated, coated steel enclosure. It includes separate HV (left) and LV (right) compartments with a steel barrier, analog gauges for monitoring, and automatic pressure relief. The unit built with copper windings, grain-oriented steel core, and a coated steel tank.

Performance

1)The structure is compact and reasonable, and the volume is small, which is only about one-third of the European-style box change of the same capacity;
2)Fully sealed, fully insulated structure, no need to set up safety barriers, and reliable guarantee for personal safety;
3)There are a variety of power supply schemes for users to choose from, which can adopt terminal power supply and realize ring network or dual power supply;
4)S11 oil-immersed power transformer is adopted, which has low loss, low temperature rise and strong overload capacity;
5)Double fuses (backup protection fuse + plug-in fuse) are used for protection, and the plug-in fuse fuse has the current and temperature dual sensitivity characteristics to ensure the safe and reliable operation of the product;
6)The 200A cable connector can be plugged and unplugged under load, and can be operated as a load switch in an emergency. It also has the characteristics of an isolating switch.
7)The winding adopts Dyn11 connection and the iron core adopts a three-phase four-column structure, so that the product can run under any asymmetric load, and the neutral point does not drift, the voltage is stable, the power supply quality is high, the cabinet heats up, the noise is low, and the lightning protection performance is good ；
8)The cabinet adopts anti-corrosion design and special spray paint treatment, beautiful and novel, suitable for various environments, and achieve the effect of beautifying the city.
