PRODUCT DESCRIPTION
Sulfur hexafluoride gas is now widely used in high-voltage electrical appliances due to its excellent insulation and arc performance. 50% of the sulfur hexafluoride gas produced in the world is used in the power industry, of which 80% is for high-voltage switchgear. More than 90% of the fully sealed loop network cabinet operated at home relies on sulfur hexafluoride gas as an insulating medium.
However, there is inevitable leakage and emission during the inflation, operation and recovery of this gas, which is an important source of pollution to the atmosphere, seriously damaging the human living environment. "Kyoto Protocol" clearly states that SF6 gas is one of six greenhouse gases. SF6 gas has been included in the list of hazardous wastes in the "National List of Hazardous Wastes" promulgated and implemented in 1998. The global warming coefficient of SF6 gas molecules is 24,000 to 2.6 million times higher than that of CO2 gas molecules, according to statistics, SF6 gas annually consumed by distribution system exceeds 4500 tons of CO2 emissions.
The life of SF6 gas molecules in the atmosphere is 3400 years, whose impact on the human environment lasts hundreds of generations, with far more adverse effects of CO2 gas. In recent years in the whole world, especially in the northern hemisphere, there had been a steep rising trend of SF6 gas concentration in the atmosphere, attracting more and more attention of the international community.
Therefore, using as little SF6 gas as possible or not using it, and vigorously promoting new technologies and alternative products have become a consensus in the industry of production and use of high-voltage switch. Our company follow the principle of using less SF6 gas or not using it, and independently researches and develops SGXGN-12 solid to insulate the loop network cabinet based on systematic study, study, and learning from similar foreign products.
