SF6 Air Sensor evacuation for middle voltages

SF6 Air Sensor evacuation for middle voltages

Each of the six fluorine atoms shares two its electrons with the outer shell of the sulfur atom in the middle. This structure gives sf 6 its stability over a broad range of temperatures; the gas is thermally stable up to 500&C. sf 6 is often used in high voltage breakers. One example is the so-called dead tank breaker.
