75kVA Three Phase Pad Mounted Transformer Step Down 4160V To 208V 120V Electrical Power Transformers
WINLEY's three-phase pad mounted transformers are widely supplied to the North American market, especially the United States. We are committed to providing high-quality, reliable, and efficient power distribution solutions to meet our customers' needs.
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.
