The shaft insulator is used for the rapping of discharge electrodes, acting as the role of rotation and isolator.
The shaft insulator assembled with the cast iron flanges by Portland cement or high temperature resisting gluing. A buffer layer is put on for the purpose of preventing loosening and turning from the end so the mechanical strength is guaranteed.
