YD-FG311 - GPO-3 Insulation Sheet
GPO-3 insulation sheet is a high-performance composite material made from fiberglass-reinforced unsaturated polyester resin. It offers excellent electrical insulation properties, good mechanical strength, and outstanding heat resistance and flame retardancy. This material is widely used in low-voltage electrical equipment for applications such as insulating supports, barriers, cable partitions, and motor end covers—especially in environments that require high arc resistance and tracking resistance. With stable dimensions and good machinability, it can be precisely processed by sawing, drilling, and other methods, making it an ideal insulation material for modern power systems and electrical equipment.
