High-voltage circuit-breakers and gas-insulated switchgear with SF6 as the insulating, switching, and quenching gas remain in our product range. They form the basis for the new development, whose vacuum switching, and so-called clean air technologies allow them to work without any SF6 at all. A vacuum interrupter unit handles the switching and arc quenching functions, while industrially treated and purified air provides the insulation for the current-carrying conductors inside the housing. "We are very pleased to have the opportunity to work with Iljin on the development and production of an environmentally friendly 170 kV GIS in Korea," says Cedrik Neike, Member of the Managing Board of Siemens AG. "By developing these innovative products, we play our part in Koreas future environmentally friendly energy landscape." After the recent milestone of commissioning the first Vacuum-Clean-Air Circuit-breakers and Clean-Air Instrument Transformers in the German 110 kV high-voltage grid was reached in June 2018, the next step is the further development for the 170 kV level.
Jung-Suk Huh, CEO of Iljin, says, "By developing this modern GIS, based on the extensive technological experience and knowledge of the two companies, we will be able to meet Korea's demand for environmentally friendly products."
