3 phase pad mounted transformer sizes 3000Kva Step-Down 12000V to
630Y/364
summary
The three phase pad mounted transformer immerses the load switch
and fuse on the high voltage side of the transformer with the core
and windings of the transformer in the same oil tank, has the
advantages of advanced structure, reliable performance, energy
saving and consumption reduction, flexible use, strong
adaptability, and economical advantages.

Application
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.
