Vertical electric cage tap-changer - series-parallel conversion

Off circuit cage type tap changer

Vertical electric cage tap-changer - series-parallel conversion

This series of tap changer is composed of an electric transmission mechanism, tap changer body and an electric controller. It is used for oil-immersed transformers with rated voltages of 10kV and 35kV and rated currents of 800A and below. Tap switching in the non-excitation state can be operated electrically or manually. Used in conjunction with our company's electric controller JLK-718A.

This tap changer can only be operated when the transformer is de-energized.
