Abstract：The development of new generation eco-friendly gas insulating equipment to promote the green upgrade of power transmission and distribution equipment manufacturing industry meets the strategic needs of building a clean and low-carbon energy system. In this paper, based on the Review Part I, we focused on the research progress of perfluoroisobutyronitrile (C4F7N) performance at application level. Firstly, current studies on the compatibility of C4F7N with metal and non-metallic materials were summarized. The gas-solid interface stability of C4F7N was also evaluated. Secondly, the biological safety parameters of C4F7N and its gas mixture were analyzed, and relevant targeted application protection suggestions were proposed. Finally, the development of C4F7N based gas insulated power transmission and distribution equipment as well as their application status were reviewed. The main problems and future development trends of eco-friendly gas insulating medium were also prospected.
