Transformer Features

        This 315 KVA pad-mounted transformer comes in single and three-phase configurations with a voltage rating of 2,400 – 46,000 V on the primary side and 208Y/120 V to 14,400 V on the secondary side. 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 pad-mount unit can be used for indoor or outdoor applications. This transformer is primarily used in Electric power distribution, stepping down primary voltage, energy management systems, and underground industrial power distribution.
