Nexans successfully achieves electrical Type Test for 525 kV DC GIS cable sealing end28.04.2021
Nexans has achieved electrical Type Test of a 525 kV DC gas insulated switchgear (GIS) sealing end according to CIGRE TB 496 with the cooperation of Siemens Energy
In the frame of the high voltage direct current (HVDC) market, the cables with an insulation composed of cross-linked polyethylene (XLPE) have emerged in the last ten years and allowed the deployment of innovative electrical grids in Europe and worldwide. Nexans’ ecosystem encompasses best-in-class partners who share our values, working together to continually deepen our ability to stay a step ahead of what the market needs.
GIS type ends constitute an interesting component in the HVDC links due to the flexibility and compaction they allow in the connection of cables of different structures, especially in congested spaces such as an offshore platform. It is also suitable for use in back-to-back mode, thus constituting a mixed joint (e.g. between cables of different technologies).
- Nexans developed a dedicated GIS cable sealing end for a 525 kV DC XLPE cable system. The studies on electro-thermal aspects of the interface resulted in an optimized accessory design. The solution consists in a Nexans GIS termination plugged in a Siemens Energy DC GIS enclosure both compliant with IEC 62271-209 standards dimensions.
- The validation of the solution has been successfully completed through an electrical 525 kV DC VSC Type Test according to CIGRE TB 496. The test was accomplished in Nexans Calais high voltage laboratory under the certification of an independent third-party. This technologic breakthrough allows Nexans to offer competitive products for the deployment of HVDC links with direct connection to DC GIS.
At Nexans, we are leading the charge to the new world of electrification: safer, sustainable, renewable, decarbonized and accessible to everyone – connecting us all to new opportunities, technologies and behaviours that will build a better future.
