HD Hyundai Electric has passed a final hurdle to export its eco-friendly circuit breakers to Sweden, cementing its product lineups in a European market known for environmental strictness. The Korean industrial electric equipment developer said Sunday it recently successfully tested its 145kV SF6-free circuit breaker with its client from Sweden present. SF6, or sulfur hexafluoride, has a global warming potential 23,500 times that of carbon dioxide. In 2024, the European Union tightened regulations on fluorinated greenhouse gases, or F-gases, increasing legal restrictions on artificial gases such as refrigerants (HFCs), semiconductor cleaning solvents (PFCs) and insulating gas (SF6). According to the Korean company, the bloc plans to ban SF6 in circuit breakers with capacities of 145kV or higher starting in 2032. HD Hyundai Electric said the EU regulations are expected to increase demands for high-voltage circuit breakers with zero SF6. Following its final test, the Korean firm’s SF6-free circuit breaker will be supplied to a substation run by a Swedish utility company. HD Hyundai Electri
