The UBB is a selector switch type of on-load tap-changer. It is designed for mounting inside of the transformer tank, but many of the features and benefits our customers appreciate from our UZ on-tank technology. This combination of the best qualities from both types of tap-changer makes the UBB model unique in its design and operation. Primarily designed for the small and medium sized transformer, the unit is compact and cost effective compared to equivalent diverter switch types of tap-changers.
