Nexans successfully achieves electrical Type Test for 525 kV DC GIS cable sealing end

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).

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.
