Space limitations are an issue with numerous new applications for HVDC transmission. That’s why Siemens Energy has broken new ground in insulation technology to make one of the most space-saving technologies in HV power transmission available for HVDC systems: gas-insulated switchgear (GIS). Siemens Energy DC GIS are based on Siemens Energy’s proven 8DQ1 switchgear technology. The encapsulated, compact, and modular gas-insulated switchgear for DC voltages of up to ±550 kV and currents of up to 5 kA reduce space requirements for HVDC switchyards considerably, boast outstanding climatic resistance. Furthermore, a gas-insulated substation can even be installed underground or commissioned in prefabricated container modules for further space and time savings as well as minimum visual impact.
Modular Siemens Energy DC GIS help reduce the space requirements for HVDC systems, ensure safe and reliable operation even in demanding onshore and offshore applications, and enable quick project implementation.
Siemens Energy DC GIS is a fairly new technology, but thanks to its great advantages it has already been included in the design of future HVDC projects that are being planned at the moment.
