The level of research and development of insulation materials is one of the key factors that affect and restrict the development of electrical technology. From the perspective of future trends, it is required to develop high-voltage resistant, heat-resistant insulation, impact-resistant, environmentally friendly insulation, composite insulation, corrosion-resistant, water-resistant, oil-resistant, deep cold-resistant, radiation-resistant and flame-retardant materials, and develop environmentally friendly and energy-saving materials.
The focus is on developing epoxy mica insulation systems for high-voltage and large-capacity generators, such as FR5, phlogopite, etc.; F and H grade insulation series for small and medium-sized motors, such as unsaturated polyester resin glass felt boards, etc.; sulfur hexafluoride gaseous media for high-voltage transmission and transformation equipment; new non-toxic synthetic media to replace chlorinated biphenyls; high-performance insulating oil; synthetic paper composite insulation; flame-retardant rubber and plastic materials and surface protection materials, etc. At the same time, we must actively promote the replacement of traditional electrical equipment insulation materials.
