CONNEX Socket, Size 5-S, for Transformer, up to 145 kV

Application:

  • Socket for mounting into transformers and other oil-insulated equipment.

Characteristics:

  • Compact design of the socket allows very small cable boxes and reduction of insulation oil
  • Preassembled Ventilation Valve for vertically installation of the socket, e.g. for mounting pluggable bushings or surge arresters
  • Transformer testing 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)
