  • Moving Toward SF6-Free High Voltage Circuit Breakers

    Although the industry has had success with non-SF6 alternatives in low and medium voltage (up to 72.5 kV) equipment, alternatives for high voltage equipment have proven to be more challenging.1 New high voltage non-SF6 gas insulated alternatives have recently become more promising, with early adoption both in the

  • What are the alternatives to SF6 gas?

    Mar 31, 2020It’s great at preventing short circuits in medium- and high-voltage electrical installations that would otherwise lead to damage, disruption, fire or explosion. Unfortunately, SF 6 is also believed to be the world’s most potent greenhouse gas, with a global warming potential 23,500 times more, kg for kg,
