With the application of high purity sulfur hexafluoride electrical equipment in China,the consumption of sulfur hexafluoride is increasing.But if the gas contains moisture,it will cause great harm to the electrical equipment.Below,small make up to say!

　　In the presence of water,high-purity sulfur hexafluoride will decompose and hydrolyze,which hinders the recombination of sulfur hexafluoride decomposition products and reduces the strength of its medium recovery,thus reducing the insulation characteristics of the equipment.

　　Impure gas will aggravate the hydrolysis of low fluoride and the decomposition of metal fluoride.High purity sulfur hexafluoride hydrolyzed substances are highly toxic,harmful to human body,electrodes and insulation materials are also very corrosive.

　　Condensation in the equipment.Because the water in sulfur hexafluoride gas exists in the form of water vapor,when the temperature drops,dew may form inside the equipment and adhere to the surface of the equipment,which is easy to produce surface discharge,causing accidents.For more information,call 139-4929-0069.
