Specifically, the column assembly extends along the height direction of the subway screen door and the lower end of the column assembly is fixed to the platform. Usually, the column assembly is isolated from the ground by insulating components at the upper and lower ends of the column assembly, thereby achieving insulation of the column assembly. In this way, there is no risk of electric shock even if the passenger touches the column assembly while getting on or off the subway.
