Pfisterer CONNEX Separable Connector
CONNEX Separable Connector, Size 4, up to 72.5 kV
- Pluggable separable connector for all XLPE cables
- Available as factory-tested and preassembled field installation cable
The dry pluggable CONNEX connection system connects the transformer, MV and HV GIS without timeconsuming SF6 gas work.
CONNEX connection joints in cast resin technology up to 170 kV enable pluggable connections that can be separated quickly if necessary. The longitudinal water barrier prevents water penetration as a result of cable faults.
The solid-insulated CONNEX connections are maintenance-free and the only ones on the market with. DNV – GL certification.
- The separable connector is installed without any gas- and oil work at the transformer or GIS
- Considerably reduced installation time and safe installation
- Horizontal, vertical and angled versions for connection to GIS and transformers
- Rapid separation and change of cable and equipment possible
- Touchproof, submersible, and maintenance-free
- Routine-tested from factory
