250Kva Single Phase Pad Mounted Transformer Oil Immersed Power
Electrical Distribution 4160V
structure
Summarization
1)Single phase pad mounted transformers are placed inside a cabinet
with doors and locks, usuallylocated outdoors. These transformers
are manulactured with ratings from 15-250 kVA.
2)Al of these distribution transformers are oil-insulated,
sef-cooled,available in loop or radial feed, and are dead-front
3)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.
