Switchgear for electricity distribution application such as: Secondary Substations, Manufacturing, Shopping centres, Airport, Small/ Medium size Power Plants, Building, etc. The Switch Disconnector Cubicle, type SDC is mainly used as an incoming, ring or branch cubicle. The Basic Unit is equipped with an SF6-insulated, 3-position Load Break Switch type SFG with its operation mechanism. The 3-position Load Break Switch may be in one of three positions, ” closed” , ” open” or “ earthed” , therefore preventing incorrect operation. Access to the cable compartment is possible in earthed position. “ Open” and “ earthed” positions are “ visible” through the inspection windows placed behind the low voltage compartment door. Inspection of cable connections and fault indicators, when used, is easily carried out through the front-door window. For safe cable testing a unique interlocking mechanism is included as standard feature.
