As an insulating gas in medium and high voltage electrical systems, it plays a role in arc extinguishing protection and has a low "global warming potential" (GWP). It is a high-quality alternative material to the conventional insulating gas SF₆ (a potent greenhouse gas) and is commonly used for insulation and protection of medium and high voltage transmission and distribution infrastructure. In commercial power grid equipment, replacing SF₆ with fluorinated special gas mixture can reduce 99% of carbon emissions and greatly reduce the impact on the environment. It has the characteristics of non flammability, high dielectric strength, etc. When used according to design requirements, it can improve workplace safety.
