SF6free
SF6free refers to technology or equipment that does not contain sulfur hexafluoride (SF6), a potent greenhouse gas commonly used as an insulating and arc-quenching medium in electrical switchgear, circuit breakers, and other high-voltage devices. Due to its high global warming potential (GWP), SF6 has been identified as a significant contributor to climate change, leading to increasing efforts to develop SF6-free alternatives.
The main motivation behind SF6free technologies is environmental sustainability. SF6 has a GWP that is approximately
Developments in SF6free solutions include the use of alternative gases such as clean air, mixture of gases
The adoption of SF6free equipment is gradually increasing across various sectors, especially in power transmission and
While SF6free technologies represent significant progress, challenges remain in ensuring long-term operational stability, cost-effectiveness, and standardization
