Vertical electric cage type tap changer-voltage central regulation

Consisting of an electric transmission mechanism, a switch body, and an electric controller, this series of switches is applicable to oil-immersed transformers with a maximum equipment voltage of 126 kV or lower and a rated current of 1250A or lower. The tap switching can be performed either electrically or manually in the non-excitation state. These switches are designed to be used together with our company’s electric controller JLK-718A.

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