Sulfur hexafluoride has high thermal and chemical stability at 150°C. Does not work with water, acids, alkalis, halogens, oxygen, hydrogen, carbon, silver, copper and insulating materials, does not decompose at 500T; In addition, Sulfur Hexafluoride also has good insulation properties and arc extinguishing capabilities. Its breakdown strength is about 2.3 times that of nitrogen or air. At 4 atmospheres, its breakdown strength is similar to that of a transformer oil at atmospheric pressure. Therefore, many high voltage switches use sulfur hexafluoride gas in recent years.
Although sulfur hexafluoride gas has the above advantages, under the high temperature of spark discharge and arc, it also decomposes fluorine atoms and some toxic low-fluorine compounds. Once these decomposition products are hydrolyzed, highly toxic and highly corrosive substances such as hydrogen fluoride will be produced. Therefore, when using sulfur hexafluoride must pay strict attention to moisture.

Gas Inflatable cables, pipelines and pneumatic cables need to be filled with insulating gas, which is an integral part of the insulating or insulating layer. It is generally required that such a gas insulation or insulation layer have a high breakdown strength, chemical stability, and incombustibility. Gases commonly used for cable insulation include nitrogen, sulfur hexafluoride, freon-12 gas, and the like. Sulfur hexafluoride gas, Freon-12 gas has a much higher breakdown strength than nitrogen, and the price is higher. Their main physical properties are seen in practice.
