DW-2 Primary Switchgear - Air Insulated and Metal-Clad

SGC Withdrawable

Cubicles consist of 2 mm galvanized steel plates. By opting for this particular plate size, the cubicles are able to withstand internal arcs effortlessly, both in the cable compartment as well as in the busbar compartment. A lot of detail went into the functional design to ensure that, in the event of an internal malfunction, no bursts of flames can move between plating surfaces, the door or between cubicles. Possible internal arcs are also guaranteed to be restricted to the compartment where they originated. The roof of the cubicle can be easily dismantled to provide smooth access to the busbar during installation and/or maintenance activities.
