The development trend of insulating materials

The level of research and development of insulating materials is one of the keys that affects and restricts the development of electrical technology. From the perspective of future trends, it is required to develop high-voltage, heat-resistant insulation, impact resistance, environmentally friendly insulation, composite insulation, corrosion resistance, water resistance, oil resistance, cryogenic resistance, radiation resistance and flame retardant materials, and the development of environmentally friendly and energy-saving materials. The focus is on the development of epoxy mica insulation systems for high-voltage and large-capacity generators, such as FR5, phlogopite, etc.; F and H-class insulation series for small and medium-sized motors, such as unsaturated polyester resin glass mat panels, etc.; high-voltage transmission and transformation Sulfur hexafluoride gaseous medium for electrical equipment; new non-toxic synthetic medium to replace chlorinated biphenyl; high-performance insulating oil; synthetic paper composite insulation; flame-retardant rubber and plastic materials and surface protection materials, etc., while actively promoting traditional Replacement of insulation materials for electrical equipment.
