New high voltage non-SF. 6. gas insulated alternatives have recently become more promising, with early adoption both in the United States and abroad. Utilities may

2021-3-18SF6 gas insulated switchgear is utilized as insulation between the earthed metal enclosure and live parts of the equipment. This type of switchgear is accessible from 12 KV systems to 800 KV systems. This type of SF6 insulated switchgear plays a crucial role in establishing an electrical substation in very

The integration of wind power is currently strongly on the agenda. As regards emissions, Saikkonen is able to present lower figures. “Equipment containing SF6 continuously experiences very minor leakages of 0.1–0.2 per cent per year.” In 2018, Fingrid’s SF6 emissions were 494 tonnes of carbon dioxide equivalent (CO2eq).

Gas mixture SF6-free Fluoroketone-based on a chemical compound developed for switchgear applications. Results The project is forecast to save 50% of CO2 emissions throughout the lifecycle of the equipment. These stems from 50% reduction in raw materials, manufacturing, thermal losses and 50% reduction in SF6 emissions
