200KVA Single Phase Pad Mounted Transformer IEEE ANSI 34500V to
120V
Summarization
1)Single phase pad mounted transformers are placed inside a cabinet
with doors and locks, usuallylocated outdoors.
2)These transformers are manulactured with ratings from 15-250 kVA.
3)Al of these distribution transformers are oil-insulated,
sef-cooled,available in loop or radial feed, and are dead-front
4)These transformers come in two basic configurations radia and
loop feed,which are selectied based on the type of circuit on which
the transformers wil be insalled.
