As these two videos show, the clean air technology used in our Blue switchgear is the only viable and sustainable way forward.
Developing a 420 kV SF6-free solution isn’t easy. But it is possible. And it’s available now, because climate change demands we act now to reduce the GWP of high-voltage products to Zero. Siemens Energy is supplying SSEN with a 600 m gas-insulated busduct which cuts out 3 tons of SF6, by using clean air insulation instead, which is the equivalent of 75,000 tons of CO2. Connecting new renewable generation to the grid by operating at 420 kV voltage level. A significant step towards reducing the use of F-gases to Zero.
Close cooperation with Netze BW was essential to the development of their new high-voltage substation in Burladingen, southern Germany. It is the first in the world to be ecoefficient, to operate without SF6 and to use digitalization to achieve new levels of connectivity. Both parties have gained enormously from the project in terms of acquiring knowledge – but of course the biggest beneficiary will be the planet.
