  "account": "HD Hyundai Electric has unveiled Korea's inaugural eco-friendly 420kV power breaker, bolstering its entry into Europe's burgeoning market for green power equipment. The company announced on Monday that it had finalized the development of the 420kV-class circuit breaker, marking the first such achievement by a Korean firm and the third globally.\n\nThis environmentally conscious circuit breaker replaces sulfur hexafluoride (SF6), a powerful greenhouse gas commonly utilized in high-voltage devices, with a C4-based gas blend. The transition necessitates redesigning the insulation and interruption systems to suit the characteristics of the substitute gas. The 420kV-class product is engineered for ultra-high-voltage transmission networks, necessitating robust, enduring performance under rigorous operational conditions, which made its creation particularly demanding, as per the company.\n\nHD Hyundai Electric has been independently crafting SF6-free circuit breakers since 2021, commencing with a 170kV-class model and subsequently introducing 145kV- and 72.5kV-class variants. This latest development further solidifies the company's commitment to sustainable power solutions.",
