SF6 gas (sulfur hexafluoride) is used as an insulating and arc-extinguishing medium due to its excellent dielectric strength and thermal stability. These circuit breakers ensure fast and efficient interruption of fault currents, protecting electrical equipment and maintaining system stability. Designed for indoor and outdoor installations, they offer compact construction, high reliability, and low maintenance. SF6 circuit breakers are extensively used in substations, power plants, transmission networks, and industrial facilities for safe and uninterrupted power distribution.
