Abstract :
SULPHUR HEXAFLUORIDE (SF6) is extremely stable and inert, remains a gas down to — 62 degrees centigrade at normal pressure, and is comparable to oil in dielectric strength at only 30 pounds per square inch gauge pressure. Its dielectric strength is generally two or three times that of air although the ratio is affected by the electrode configuration, voltage wave shape, and pressure.
