WebThe weight of a 20 MVA transformer also varies depending on the cooling system. As a result, ONAN transformers are typically heavier than ONAF transformers. For example, the 20 MVA transformer weight of an oil-filled transformer is 65,036 lbs. (29500 kg.) The weight of your 20 MVA transformer will also vary depending on the accessories included. WebSistemas de refrigeración TIPO ONAF: Al igual que en el método ONAN, este enfriamiento se basa en la convección del aceite para disipar el calor mediante un movimiento natural, pero ese enfriamiento se ve apoyado por ventiladores de aire externos para el enfriamiento en las aletas del trasformador.
