ABB Three phase oil filled distribution transformers

ABB Three phase oil filled distribution transformers 

Three phase distribution transformers used to step down three-phase high voltage to low voltage for power distribution, mainly in metropolitan areas and for industrial applications. The transformers in standard versions are three phase and can be installed both outdoors and indoors. Distribution transformers are hermitically sealed (the tank is completely filled with oil) or equipped with oil conservator. Flexible corrugated tank walls enable sufficient cooling of the transformer and compensate for the changes in the oil volume during operation. An advantage of the hermitically sealed transformers is that the oil is never in contact with the atmosphere thus avoiding periodic oil analysis. Our products are manufactured in ISO 9001 and ISO 14001 certified factories.
