Abstract
A pole assembly of a switching device is provided. The pole assembly includes a first interrupter unit operably connected to a pole plate of the pole assembly via first post insulators. The first interrupter provides a path for current flow through the first interrupter in a closed state and interrupts the current flow in an open state. A second interrupter unit is operably connected to the first interrupter unit and to the pole plate via second post insulators. The second interrupter allows the current flow through the first interrupter unit in an open state and grounds the switching device in a closed state. The pole assembly includes a dielectric shield physically disposable between and operably connected to the first post insulators and the second post insulators for uniformly distributing an electric field generated during operation of the pole assembly.
