3 Phase Oil Immersed Distribution Transformer
3 Phase Oil Immersed Distribution Transformer Description
Our 3 Phase Oil Immersed Distribution Transformer can be divided into step up auto transformer and step down auto transformer. The oil tank of transformer adopts corrugated oil tank, and the oil conservator is canceled. The tank cover is completely welded with the tank edge or fastened with bolts, which extends the service life of the transformer oil. Our MVA distribution transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
