Product Description
This type of tap changer is designed as step changeable facility used for capacity regulating transformer under non-energized condition. It is suitable for three-phase oi-immersed capacity regulating with voltage rated 10kV and below, rated capacity 315kVA and below. It can be connected in series and parallel system on LV and HV windings or connected b star or delta method through which to realize transformer capacity changeable. By this way we can reduce iron loss and increase transformer load efficiency and power factor avoiding the phenomenon of "Big horse will drag small carriage", and can be used to regulate voltage terminals.
