Vacuum interrupting technology and clean air insulation for wind turbine applications
Enabling higher voltage levels within wind turbines
It is essential to raise environmental awareness and increase resource efficiency, and offshore wind power is making a major contribution to meeting these challenges. Growing power demand requires a new generation of wind power plants equipped with innovative technologies.
One core aspect: Due to increased wind turbine power, there is a movement to higher voltages within the wind turbine network to decrease the current and therefore the cable losses. This is where compact, environmentally friendly, gasinsulated high-voltage switchgear can make an optimal contribution.
Clean air as insulating medium
Vacuum interrupting technology facilitates the implementation of clean air as insulating medium in gas-insulated switchgears.
Clean air technology from Siemens Energy is free of fluorinated greenhouse gases and it supports the company’s goal to develop completely environmentally friendly technologies.
Clean air is composed of 80 % nitrogen and 20 % oxygen, cleaned and free of humidity.
Clean air technology has a Global Warming Potential (GWP) of 0. It is a non-toxic, non-harmful and safe medium.
No specially trained personnel is needed for the transport, handling, or operation of the clean air GIS. Expensive purchasing, handling, and recycling costs of sulfur-hexafluorinate (SF6) or other gases do not apply.
