Three Phase Pad Mounted Compact Type Distribution Transformer

Three-Phase Pad-Mounted Compact Type
 
Compact Type is a three-phase pad-mounted transformer housed in a minimum profile enclosure. It is designed for applications requiring three-phase service in a small, unobtrusive package and is the ideal choice for small commercial loads. The design is easier to handle, install and maintain. Its removable flip-up hood allows easy access to the terminal compartment.
