Curtain mechanism
The curtain mechanism is designed to restrict operating personnel's access to the live parts of the cable compartment and the busbar compartment from the chassis cart compartment of Switchgear Panels / Cubicles when the chassis cart is in the test position or withdrawn from the cubicle.

The curtain mechanism consists of guides 1, curtains 2, and levers 4, which rotate around the axis 5 under the action of pushers located on the chassis cart. Rotating, the levers drive the curtains by means of pull rods 3. At the customer's request, the curtain mechanism can be equipped with guide rails 6, 7 for the chassis cart. The right guide rail 7 has installation sites 8 for mounting an interlock kit to arrange operational interlocking between the chassis cart and the FES.
All parts of the curtain mechanism are made of galvanized steel. The curtains are coated with red powder paint (by default). The color of the curtains can be changed at the customer's request.
