Medium Voltage Cubicle Switch Disconnector with Fuse SDF - ABB

Uniswitch is an air insulated ( AIS) , metal enclosed, switchgear cubicle design of the next generation developed through continous innovation and vision to meet the changing market needs. Switchgear for electricity distribution application such as: Secondary Substations, Manufacturing, Shopping centres, Airport, Small/ Medium size Power Plants, Building, etc The Fused Switch Disconnector Cubicle, type SDF is primarily used for Transformer Protection & Voltage metering. The Basic Unit is equipped with an SF6-insulated, 3-position Load Break Switch type SFG with its operation mechanism. For fuse earthing, the integrated earthing switch operates on the upstream side and separate earthing switch operates on the downstream side of the fuse.The mechanism used is a double spring mechanism with automatic fuse tripping for Transformer Protection. 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.
