225kva 3 Phase Pad Mounted Transformer 34500V To 480V ANSI/IEEE Standards UL Certification
summary
A padmount transformer is a ground-mounted utility distribution transformer, which usually is housed in a locked metal cabinet,situated on a small concrete pad. They are usually manufactured in power ratings from around 75 to around 5000 kVa and often includes built-in fuses and switches. A typical enclosure includes a tank for holding the core/coil assembly of the padmounted transformer immersed in oil or the like, and a wiring cabinet having high and low voltage wiring compartments for enclosing the high and low voltage bushings, respectively, of the transformer, etc. Our pad mounted transformer is design and tested in accordance with industry standards including CSA,ANSI C.57,DOE,and IEEE as applicable.

STRUCTURE
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.
