Product Description

300Kva Three phase pad mounted Transformer Loop Feed 13800V to 208Y120V



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.
