Product Details
Outstanding Features
SSPGS is puffer interrupting pad mounted fully deadfront switchgear for underground systems up to 25.8kV, 630A, enclosed in stainless steel tank full of SF6 gas insulation media. It incorporates grounding switches in every way to provide added safety and faster working.
SF6 Gas Insulation Media which is enclosed in stainless steel tank sealed for life and maintenance free with less than 0.2% leakage rate per year
Normal insulation and interruption performance even at an atmospheric gas pressure
Unique and field proven puffer and heavy duty tulip-shaped contacts made of arc resistant Cu-W tip
Internal power source through integrated capacitor-potential transformer combination for the control circuit's power
Three phase group-operated mechanism offers regular close-open speed regardless of operating speed or method (manual or electrical)
Front ground circuit bushings offer easy cable testing
Deadfront design and mechanical interlock between main and earth switch provides a high level of safety and efficient maintenance.
Integrated capacitive voltage sensors, CT's and internal power supply makes this switch easy to be installed in SCADA system
