50Kva Single Phase Pad Mounted Transformer step down 12.47Kv to
208V
Single phase pad mounted transformer is oil-immersed distribution
transformer.The traditional transformer is designed in a box-type
shell. It has the characteristics of small size, light weight, low
noise, low loss, safety and reliability.It is widely used in
residential quarters, commercial centers, hospitals, parks,
schools, etc.Single phase pad mounted transformers are self-cooled,
available in loop or radial feed, and are dead front,Meet or
exceeds ANSI /CSA/IEEE standards.
