Switch Disconnector Cubicle, type SDC
 

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 switch

disconnector type SFG with its operation mechanism. The 3-position switch disconnector 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.
