"Oil immersed transformers are one of oldest type of transformer and still most of industrial area using oil immersed transformer." 

Transformers cooled and insulated by insulating oil are widely used in power generation, power grid infrastructures, and industrial applications. With more than 30 years' experience in engineering and manufacturing, Sanil has been recognized as quality supplier of oil immersed transformers and exports its products to more than 20 countries worldwide. 
 Sanil oil immersed transformers were type tested in KEMA and KERI. Short circuit test was performed successfully for 20MVA transformer.
 Custom built design for special customer demands led to more than USD 15 million annual export to utilities and oil companies in Middle East.
