F862, similar to IEC EPGM203, is a sheet material made by impregnating alkali-free glass fiber mat with heat-resistant resin and then hot-pressing it. Using alkali-free short-cut glass fiber mat as the reinforcing material, F863 made by impregnating it with epoxy adhesive and compressing, it have excellent mechanical properties and processability. They are commonly used to manufacture large electrical equipment (such as generator sets and transformers) as fasteners, mainly processed into screws, nuts, grooves, wedges, supports, and fixtures, used for securing the end of the windings of large steam turbine generators. This overcomes the creeping phenomenon that is prone to occur with metal fasteners, thereby significantly improving the reliability of large generators during operation.
Product Description
EPGM203 ( F862 ) Epoxy Glass Mat Products is a highperformance glass fiber mat laminate compliant with IEC 60371 standards, manufactured by impregnating alkalifree glass fiber mats with hightemperature resistant epoxy resin through a hotpressing process. Designed for highvoltage electrical equipment, renewable energy systems, and rail transportation, it offers exceptional electrical insulation, mechanical strength, and environmental durability, serving as a costeffective alternative to imported equivalents in power transmission, industrial automation, and advanced manufacturing applications.
