Product Feature
Non excitation tap changer is suitable for three-phase oil immersed transformer. Under the condition of non excitation, the secondary voltage can be adjusted by changing the number of turns of the transformer's primary coil. The three-phase oil immersed transformer non excitation voltage regulating switch produced by hengfengyou has the advantages of simple structure and low cost. It is used in occasions where the voltage requirement is not too high and there is no need for frequent regulation.
