Sustainability by technology

Blue portfolio – combine high-tech performance, easy operation and sustainability

Since global carbon emissions in 2019 hit an all-time high record of 36.8 billion metric tons, the pressure on power utilities to expedite their decarbonization efforts is increasing!

Our blue portfolio makes it possible to modernize and expand the existing power grids at the highest level of safety and to simultaneously reduce our ecological footprint to an enormous extent without having to compromise on performance and economic feasibility. The combination of vacuum switching technology and clean air insulation reduces emissions while greatly increasing the recycling rate – without maintenance. The outstanding technical performance and low lifecycle costs makes it a perfect choice for substation products up to 145 kV. The technology is available for gas-insulated switchgear, circuit breakers and instrument transformers all with absolutely zero CO2 equivalent emissions over the lifetime of the equipment.
