Leilang Electric proudly presents the 2.5MVA (2500KVA) Conservator Type Oil-Immersed Substation Transformer (24940V to 480Y/277V), engineered and manufactured in strict compliance with ANSI/IEEE, DOE, CSA and ASTM international standards for North American power distribution systems. This pad-mounted radial feed transformer features KNAN/KNAF dual cooling technology and high-purity copper windings, delivering exceptional overload capacity, long-term reliability and energy efficiency for industrial parks, commercial centers, data centers and utility grid applications.
Our 2.5MVA conservator type transformer adopts an advanced oil expansion system that effectively isolates insulating oil from air, preventing moisture ingress and oil oxidation, significantly extending service life. Equipped with a grain-oriented silicon steel core and 5-position off-load tap changer, it maintains stable voltage output even under fluctuating load conditions. The transformer is designed to operate reliably in extreme temperatures ranging from -40°C to +40°C, making it suitable for harsh environmental conditions across North America.
Every unit undergoes 9+ rigorous factory tests before shipment to guarantee compliance with all stated performance parameters. With a production capacity of 500 units per month and a standard lead time of 30 days, Leilang Electric can fulfill both small and large-scale orders efficiently. All our transformers come with a 24-month comprehensive warranty from the bill of lading date, backed by lifetime technical support and free replacement of easily damaged accessories.
