    4. Structure Introduction
    JT8(JN)-40.5 Type indoor high voltage grounding switch from the undercarriage, touch knife, insulator voltage display devices (sensors), closing spring, and three-phase short-circuit connection contact copper components.
    Brace is bent plate welded into a rectangular frame. Supply at both ends with the assembly of the spindle bearings and bearing; a display device voltage insulator (sensor) installed in the bottom frame and top with J-type contact and bearing; touch knife spindle mounted welding Shui arm, by closing spring drive shaft and drive the touch knife switch on, so as to achieve the purpose of closing short-circuit current.
    When open and close, as long as the operating handle is rotated with the spindle drive shaft coupled to the spring over the dead point, closing by spring force acceleration. After closing the main shaft connecting the crank arm and the operating shaft into a dead point, it is possible to closing short-circuit current, touch knife does not open when the dynamic current test.

    5. Ordering Information
    The grounding switch for a wide range of products please specify the user type, size, distance, or gear crank arm mounting position (left or right), whether with live display device. User if there are special requirements, when ordering.
