The THV on-load tap-changer is a composite structure that combines the functions of a diverter switch and a tap selector to form a selector switch that assumes both tap selection and load current switching.

Product DescriptionThe CT35 mechanism is a double clamp plate structure with a smaller overall size. The manual opening and closing operation, energy storage operation, counting indication, opening and closing indication, and energy storage indication of the mechanism are all on one surface, making it easy to operate and use. The mechanism adopts a driving claw driven block energy storage structure, which is easy to adjust and reliable in energy storage.

Product DescriptionThe CT17 spring operating mechanism adopts a clamp type structure, with the energy storage motor and driving part, closing cam and connecting rod, auxiliary switch, etc. arranged in the middle of the left and right side plates, ensuring reasonable force and good stability of each part. The closing spring, wiring terminal, and travel switch are arranged on the outer side of the side panel for easy maintenance and replacement.
