25Kva Single Phase Pad Mounted Transformer Oil-immersed 34500V To 120V MV&HV Ground-Mounted Transformer

This 25 kVA single-phase pad-mounted transformer features a liquid-filled design for loop feed to 3-phase grids. With 34500V primary and 120/240V secondary, it uses a 5-position tap changer for voltage adjustment. Equipped with dead-front primary and live-front secondary connections, plus a load break switch, it ensures safe operation. Using biodegradable oil, it meets strict efficiency standards (98.7%), offers weatherproof NEMA 3R housing, and suits outdoor use up to 3300ft. Its low-loss, low-noise design balances reliability and eco-friendliness.
