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.

Key words： Eco-friendly gas C₄F₇N gas mixture material compatibility biological safety equipment development
