Product Description

Pad Mounted Transformer Single phase oil type 12470V to 120V 25kva 37.5Kva 50Kva 75Kva 100Kva



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.
