Pfisterer HV-CONNEX Separable Connector System

Pfisterer MV-Connex Pluggable Connection System Advantages

  • Approx. 50 % shorter mounting length compared with conventional systems in accordance with IEC62271-209 (former IEC60859)
  • No opening of the cable termination and associated costly gas or oil work
  • Horizontal, vertical and angled versions for connection to GIS and transformers
  • Considerably reduced installation times
  • The use of pre-assembled and tested components means maximum safety and efficiency
  • Installation errors are minimised
  • If a fault does arise, rapid separation of cable and equipment
  • Cable sheath test possible without unplugging
