Horizontal electric cage tap changer neutral point voltage regulation

This series consists of an electric transmission mechanism, a switch body, and an electric controller. It is designed for use in oil-immersed transformers with a maximum equipment voltage of 40.5 kV or lower and a rated current of 630A or lower. The tap and switch functions can be operated electrically or manually when the transformer is de-energized. It is specifically used in conjunction with our electric controller JLK-718A, and it is important to note that it can only be operated when the transformer is de-energized.
