Need Know Everything About GPO-3 Unsaturated Resin Laminates

What is GPO3 Insulation Board

Polyester boards mainly include GPO-3 boards and UPGM205 boards. GPO-3 boards are available in red, white, and brown-red, and are divided into light boards and matte boards. UPGM205 is a white matte board.

IEC standard: UPGM203/UPGM205

NEMA Standard: GPO-3

German standard: HM2471

GPO-3 laminate insulation material is a rigid plate-shaped insulation material made of alkali-free glass fiber mat impregnated with unsaturated polyester resin paste, and added with corresponding additives and hot-pressed. UPGM205 white matte board is a rigid plate-shaped insulating material made of alkali-free glass fiber mat soaked in unsaturated polyester resin paste, added with high-strength alkali-free glass fiber cloth and corresponding additives, and hot-pressed; with GPO -3 Compared with the upgraded product, the tensile strength and bending strength are correspondingly improved.

GPO-3 laminate insulation material is widely used as the necessary insulation material for low-voltage electrical appliances in Europe, the United States and other countries.

The definition of GPO-3 laminate insulation material in international laminates: GPO-3, also known as UPGM-203, refers to unsaturated polyester fiberglass mat material, used in machinery and electrical applications, with good electrical performance under high humidity. It has good mechanical properties at moderate temperatures, is flame retardant, has good arc resistance and resistance to leakage traces.

GPO-3 Unsaturated Resin Laminates Features:

Excellent arc resistanceExcellent arc resistance (greater than 180 seconds) and tracking resistance (CTI greater than 600 V)

Excellent heat resistance, flame retardancy, heat resistance grade reaches above 155 ℃; flame retardancy: UL 94 V-0 level. In low-voltage electrical appliances and transformers, the heat resistance of insulating materials is a very important selection index. When higher heat resistance is required for such appliances, GPO-3 materials offer good cost performance.

Excellent mechanical processing performance and high degree of automated processing. It can be processed into various parts by lathe processing, stamping, trimming, drilling, sandblasting, grinding, sawing and milling. The assembly method is simple and practical, and can be glued. Assembly methods such as connections, metal screws and riveting.

GPO-3 laminate Insulation Materials Applications :

GPO-3 laminate insulation materials are widely used as insulating structural parts in motors and electrical equipment, such as circuit breakers, switch cabinets, transformers, DC motors, AC contactors, explosion-proof electrical appliances and other low-voltage electrical appliances; in the automotive industry and other fields.

In electrical appliances and electrical industry: partitions, linings, arc extinguishing hoods, arc extinguishing cylinders, arc extinguishing blades, arc isolation plates, wiring boards, interphase insulation, bottom partitions, contact supports of various switch cabinets; switches And structural supports of transformers, busbar plywood; signal boards, insulation of electric furnaces and electric furnaces.

Motors and motors: motor armature components, movable cover plates, wedge stators, fixed washers, thin washers, carbon brush holders, etc.

In recent years, new materials such as flame retardant, impact resistance, wear resistance, non-corrosion, high dimensional stability, and high arc resistance have been vigorously developed for the insulation of motors. In motors and motor equipment, arc is the main cause of accidents and causes serious harm to workers. However, the high CTI value of GPO-3 is ≥ 600 V and the arc resistance is ≥ 180s, which ensures the safety of motors and motors.

GPO-3, also known as UPGM203, is a hard insulating material made of alkali-free glass fiber mat soaked in unsaturated polyester paste and added with corresponding additives and hot-pressed. HONY plastic produces and supplies GPO-3 insulating laminates by itself. We can also produce and process supporting parts according to customer drawings and size requirements, and can provide relevant national UL certification and ROHS reports.
