Insulated air duct Busduct

Renewable energy sources are only part of the solution as we aim for the decarbonization of the energy sector. It’s essential that we achieve Zero Global Warming Potential (GWP) in the transmission of power as well as in its generation. Most switchgear still uses SF6 for insulation – a gas 24,300 times more climate-hostile than CO2 and one which stays in the atmosphere for up to 1,000 years. Recognizing the harmfulness of this and other F-gases, the EU has legislated to restrict their use and allows only GWP < 1 solutions if available. By contrast, our future-ready Blue portfolio, including our gas-insulated busducts, uses Zero fluorinated gases of any kind and has Zero harmful impact on the environment. Zero SF6 – just clean air The sustainable, Zero harm alternative to SF6 is clean air. This is the only way to achieve Zero GWP. The Blue gas-insulated busducts operate with clean air insulation. This means Zero harmful greenhouse gases of any kind, with Zero toxic decomposition products and Zero safety requirements during handling and maintenance. The clean air used – consisting of 80% nitrogen and 20% oxygen, cleaned and free of humidity – can be released into the atmosphere with Zero harmful effects to people or the environment. At the same time, the busducts maintain the highest standards of technical performance and reliability, together with low lifecycle costs. They are capable of handling voltages up to 420 kV – while the handling, transportation and operation of the units require Zero special training
