This series of switches is composed of an electric transmission mechanism, a switch body, and an electric controller. It is designed to be used in 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 operated electrically or manually when the transformer is not in the excitation state. These switches are intended to be used in conjunction with our company’s electric controller JLK-718A.
This tap changer can only be operated when the transformer is de-energized.
