Transformer Features 

 

           This clam-shell pad-mounted oil-immeresed transformer comes in single-phase configurations with a voltage rating of 480 V on the primary side and 240/120 V on the secondary side with dual winding. This unit’s cores are made from cold-rolled silicon steel laminations using state-of-the-art technology.

         This transformer is highly energy efficient with lower heat emissions, resulting in fewer cooling requirements. The unit also features mineral oil as an insulating fluid with a 65°C temperature rise. With its NEMA Type 3R enclosure, this clam-shell pad-mount unit can be used for indoor or outdoor applications.

        This transformer is primarily used in Electric power distribution, industrial sites, electrical rooms, underground vaults, manufacturing facilities, processing plants, commercial buildings, and underground industrial power distribution.
