GE Ttransformer’s American-style box transformer puts the transformer body, high-voltage load switch, fuse, and other components together in the transformer oil tank because it is immersed in oil, the volume of components is greatly reduced, the structure is more compact, beautiful appearance, small volume, easy installation, flexible, fully insulated, fully sealed structure, safe and reliable, convenient operation, maintenance-free. The GE Ttransformer’s American-style box transformers can be divided into ring type and terminal type according to the function and structure of the high-voltage section, and are available for use outside and inside the building. They are suitable for use in digital centers, solar, wind and energy storage, industry, urban housing, street lighting, high-rise buildings, and temporary construction sites.

Pad mounted transformer features：

Small size, compact structure, small floor space, easy installation, about 1/3 of the same capacity of European type box transformer
Low loss, low noise, low-temperature rise, high load capacity over the nameplate, high resistance to sudden short circuit
Fully enclosed, fully insulated structure, safe and reliable operation
Easy to operate, easy to maintain, short production cycle, low cost of construction
Flexible wiring can be used in both terminal systems and ring grid systems.
It is easy to change over and enhances the reliability of the power supply.
Anti-corrosion design and special painting treatment for the box body, suitable for various harsh environments.
Can realize the functional requirements of on-load voltage regulation and high voltage metering
JB/T10217-2013 Combined transformer
DL/T1267-2013 Combined transformer conditions of use

Pad mounted distribution transformer structure：

The transformer body, high-voltage load switch, and protection fuse are placed in the same oil tank. The tank is a fully sealed structure with concealed high-strength bolts and an oil-resistant nitrile rubber ring sealing the cover, which can withstand 50kPa pressure for a long time. The inlet end of the apparatus adopts a fully insulated and shielded European-style cable attachment connection, and the box is designed with waterproof and anti-condensation requirements in mind, with the top cover designed with a 5% slope to prevent water accumulation.
According to the relative position of the high-voltage side, transformer, and low-voltage side, it can be divided into the pin type and the eye type, see the attached diagram for details.
