off-Circuit Capacity Regulating Tap Changer Circuit Switch

Introduction:
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.Technical parameters:Main performance parameterInsulation Leve (kV)Sealing performance (Pa/24h)Machine Life(Ten thousand times)Rated
