HV-CONNEX Socket Size 9 for GIS, up to 550 kV


  • 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)
