Medium Distribution Transformers
Medium distribution transformers
Medium distribution transformers are used to step down three-phase high voltage to low voltage for energy distribution, mainly in the countryside or low-density populated areas.
The transformers are three-phase, oil-immersed hermetically sealed, adaptable for pole-mounting or assembly in substations.
On request, the transformer can be equipped with an oil conservator and the transformer tanks surface can be hot dip zinc coating.
