CONNEX Socket, Size 7, for GIS, up to 300 kV
Application:
- Socket for mounting into gas-insulated switchgears (GIS), gas-insulated transformers, joints and other gas-insulated equipment
- Compact design of socket allows very small cable boxes and reduction of insulation gas
- Testing of switchgear in factory due to short time amount for plugging the accessories
- Assembly time is significantly reduced and safe assembling guaranteed
- Touch-proof, maintenance-free and floodable (IP67)
