Abstract:High-performance aramid insulating paper for large-scale electrical insulation equipment is the key material to ensure the reliable， durable and safe operation of the equipment， which directly affects its comprehensive quality， temperature resistance level and service life. With the large-scale application of aramid insulating paper in special electrical insulation equipment， higher requirements and challenges have been put forward for its temperature resistance grade， corona resistance performance， dielectric strength， and ability to meet miniaturization and high integration. The research progress of a series of advanced aramid insulating papers were mainly introduced in this paper， such as dense-structure aramid insulating paper， corona resistant aramid mica insulating paper， thermally conductive aramid paper and aramid insulating nanopaper， in terms of paper structure design， mechanical and insulating properties. Finally， the future development direction of high-performance aramid insulating paper was prospected.
