Pfisterer SEANEX 66kV Inner Cone Connection

The SEANEX cable connector offers a robust inner cone HV connection system.

 

SEANEX is a dry pluggable inner cone connection and contact system specifically for offshore applications up to 72.5 kV. It is based on the CONNEX system by PFISTERER for voltages up to 550 kV. SEANEX components have been optimised for requirements at sea, are DNV GL certified and meet the new IEC 63026 offshore standard.

All connections are easy to connect. On the low- voltage side with the PLUG, on the high-voltage side with SEANEX. Installation is quick and easy, and maintenance times are significantly reduced. Due to our close corperation with the transformer manufacturers very compact device designs can be realised.

Separate electrical and mechanical contact

Compared to other connection solutions, SEANEX is the much more robust system. Electrical and mechanical contacts are separate from one another. The proven lamella contact technology and spring system ensure reliable power transmission – even during sudden load changes. For installation, the SEANEX connectors simply plug into the corresponding sockets and joints, and are secured with three screws. The rotatable bell flange enables 360° installation.

  • Quick and simple installation
  • The rotatable bell flange enables 360° installation
  • Rapid separation and change of cable and equipment possible
  • Touch-safe thanks to metallic encapsulation
  • Maintenance-free
  • Saltwater resistant
  • Routine-tested from factory
  • Offshore certified by DNV GL and IEC 63026
  • Separate electrical and mechanical contact
  • Electricity flows in a line – no angles, corners or edges
  • Transition box is eliminated
  • No twisting of cables
  • Connection can be separated without loss of quality
