| Abstract:The rapid development of power grid construction and the continuous advancement of the "double carbon" plan have put forward higher requirements for the demand and performance of cellulose insulating paper. At present, insulating wood pulp for cellulose based electrical insulating paper is mainly imported, which puts forward a severe test for the localization of basic materials of electric power equipment, at the same time, the performance of traditional cellulose based electrical insulating paper can’t meet the needs of complex environments. In this context, the development of China's characteristic new fiber materials and new reinforcement materials is of great significance for improving the performance of insulating paper, alleviating the shortage of fiber raw materials, and ensuring the stable operation of power equipment. This paper summarizes the research status of novel cellulose fiber electrical insulating paper in terms of new fiber raw materials and new reinforcement materials, so as to provide new insights for the development of high performance cellulose fiber based insulating paper in the future. |
