At present, most GIL insulation media use SF6 gas, but SF6 gas has a strong greenhouse effect (global warming coefficient GWP is 23800), has a great impact on the environment, and is listed as a restricted greenhouse gas internationally. In recent years, domestic and foreign hotspots have focused on the research of SF6 alternative gases, such as the use of compressed air, SF6 mixed gas, and new environmentally friendly gases such as C4F7N, c-C4F8, CF3I, and the development of environmentally friendly GIL to improve the environmental benefits of equipment. However, environmentally friendly GIL technology is still in its infancy. The use of SF6 mixed gas or completely SF6-free environmentally friendly gas, the development of high-voltage equipment, and the promotion of environmentally friendly gas in electrical equipment and other technologies all require in-depth exploration and research.
Perfluoroisobutyronitrile, also known as heptafluoroisobutyronitrile, has a chemical formula of C4F7N and is an organic compound. Perfluoroisobutyronitrile has the advantages of good chemical stability, low temperature resistance, green environmental protection, high melting point, low volatility, and good insulation. As an insulating medium for electrical equipment, it has broad application prospects in the field of power systems.
In the future, with the acceleration of the construction of UHV projects in my country, the prosperity of the perfluoroisobutyronitrile industry will continue to improve. In terms of market competition, Chinese companies have the ability to mass produce perfluoroisobutyronitrile. In the future, with the advancement of technology and the continuous improvement of industry standards, the market share of high-quality products will continue to increase.
