500kva Three Phase Pad Mounted Transformer Ansi Standard Loop Feed
34500v To 480y/277
Performance Characteristic
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.
