CONNEX Socket, Size 4, for Transformer, up to 72.5 kV
Application:
- Socket for mounting into transformers and other oil-insulated equipment
- Transformer testing in factory due to short time amount for plugging the accessories
- Assembly time is significantly reduced and safe assembling guaranteed
- Preassembled Ventilation Valve for vertically installation of the socket, e.g. for mounting pluggable bushings or surge arresters.
- Touch-proof, maintenance-free and floodable (IP67)
