The Universal Connection System for Cables, Transformers, and GIS

The Universal Connection System

The Pfisterer Connex system is the leader in plug-in contact systems. The original Pfisterer MV Connex system became the standard on which all plug-in systems are now based. Continual research and development has increased the size and range of the products. There are now nine sizes of Connex covering 6kV up to 550kV. The system is used worldwide as a dry plug-in system for transformers and GIS switchgear. Connex connectors feature high fault ratings across the range and are suitable for all polymeric and EPR cables for both indoor and outdoor use.

Installation Training Courses are available from Intertech Enginnering for experienced Cable Jointers. Successful trainees are certified by Pfisterer for CONNEX product installation.
