The S18 Oil Immersed Transformer is another giant leap in transformer efficiency and reliability. Equipped with high permeability silicon steel cores and state of the art winding technology, the Transformer greatly reduces no-load as well as load losses, over its predecessor.
The oil immersed cooling system guarantees excellent heat dissipation so that it runs steadily not only under no load but also under full load. The transformer is a totally-enclosed construction type to prevent the penetration of moisture and oxidation of oil, and thereby enlarges service life.
The S18 transformer, U and I rated according to the international norms, is often used in the Electric Power Plant, Subsystem, Industry and City Grid. With excellent over load capacity and insulation, it provides such safe, continuous and enough electric power transmission.
