Korea's HD Hyundai Electric has unveiled the country's inaugural 420-kilovolt (kV) SF6-free high-voltage circuit breaker, a significant step in the company's drive into Europe's burgeoning market for environmentally friendly power equipment. On Monday, HD Hyundai Electric confirmed the successful completion of the 420kV-class circuit breaker's development, marking it as the first Korean firm to achieve this milestone and the third globally.
This groundbreaking eco-friendly circuit breaker substitutes sulfur hexafluoride (SF6), a potent greenhouse gas commonly employed in high-voltage equipment, with a C4-based gas mixture. The switch necessitates a redesign of the insulation and interruption systems to suit the attributes of the alternative gas. The 420kV-class product is engineered for ultra-high-voltage transmission networks and must exhibit robust, long-term performance under extreme operating conditions, rendering its development notably challenging, as per the company.
Since 2021, HD Hyundai Electric has been independently crafting SF6-free circuit breakers, commencing with a 170kV-class product and subsequently introducing 145kV- and 72.5kV-class products. This latest advancement further bolsters the company's commitment to sustainable power solutions.
