2500Kva 3750 Kva Three Phase Pad Mounted Transformer Step Down 13.8KV to 480V
A padmount or pad-mounted transformer is a ground mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformer can be installed in places that do not have room for a fenced enclosure.
