Rigid sheet-like insulating material for flame retardant
GPO-3 insulation board is also known as GPO-3 laminate. It is a rigid plate-shaped insulating material made of alkali-free glass fiber mat impregnated with unsaturated polyester resin paste, adding corresponding additives and hot pressing.

GPO-3 insulation board is also known as GPO-3 laminate. It is a rigid plate-shaped insulating material made of alkali-free glass fiber mat impregnated with unsaturated polyester resin paste, adding corresponding additives and hot pressing. GPO-3 insulation board, also known as UPGM-203, refers to unsaturated polyester fiberglass mat material, mechanical and electrical, good electrical performance under high humidity, good mechanical performance under medium temperature, flame retardant, durable Good resistance to arcing and creepage marks.
Specifications: 0.8~100mm, 914×1828mm, 1220×2440mm
Color: white, brown red, etc.

GPO-3 insulation board electrical insulation
All electrically insulating laminates are inherently excellent insulators. According to the characteristics of the grade, it is widely used in electrical aspects in the field of engineering technology by utilizing its optimized special performance.
Flame retardant performance of GPO-3 insulation board
Grades 1580 and UTR are UL-rated V-0. Grade UTR is halogen-free, and the system emits very little smoke and toxic fumes in case of fire.
Mechanical strength
High-strength fiberglass-reinforced polyester laminate won't shatter. Rigid laminates provide structural support due to their insulating properties. Flexible laminates are available for applications with a minimum bend diameter of 19mm.
Heat resistance
Durostone® Glastic® laminate offers excellent protective properties and dimensional stability during elevated temperatures. These laminates have UL temperature ratings in the 120-210°C electrical and 130-210°C mechanical ranges.
Easy to form
These materials are easily machined and formed using standard metal handling equipment. Can be stamped, drilled, machined, sheared and sanded. Grade UTR is known in machining centers for its ease of high-speed molding. Grade 1580 punches cleanly and quickly.

GPO-3 insulation board application
Application in circuit breakers: Frame type circuit breakers: safety baffles, safety shutters, spacers, interphase partitions, etc.
Applications in molded case circuit breakers: interphase partitions, arc partitions in arc extinguishing chambers, etc.
Application in electric motors: motor armature parts, movable cover plate, slot wedge stator, fixed gasket, thin gasket, carbon brush holder, etc.
Application in switchgear: front end, rear end, upper end, bottom end, interphase partition in the partition system, etc. Other applications: arc-resistant structural parts

How to distinguish real GPO-3
1. The real GPO-3 insulating board has passed the American safety laboratory certification (UL certification), so it has an independent UL identification file number. When purchasing this product, the manufacturer should be required to provide the UL identification file number to identify the authenticity .
2. The leakage resistance index of real GPO-3 board can reach 600V.
3. The real GPO-3 board has a density between 1.81--1.83 according to international standards and does not contain fillers, which determines the reliability and stability of the board.
A simple method for distinguishing finished and inferior products of GPO-3 insulation boards
Can be lit with matches.
1. Those with smoke and dust are inferior products. The adhesion of GPO-3 insulation board products is very good, and the material itself is environmentally friendly and does not generate smoke and dust.
2. Toxic gas is produced. Inferior products generally use flame retardants to achieve flame retardant effects, so there is a pungent poisonous gas when burned. As the flame retardant volatilizes, the performance of the product will also decrease, so it cannot be used in an environment where people are in contact with it or in an environment with heat.
3. Combustion stratification, due to the irregular structure of the glass fiber mat, the mechanical tension of GPO-3 comes from the inside, and internal stratification will not occur during high-temperature carbonization. If there is stratification in combustion, it is a counterfeit product.

GPO-3 Application 

GPO-3 light board red, white, brown red series, widely used in electrical machinery, electrical equipment as insulating structural parts, such as electrical breakers, switch cabinets, transformers, DC motors, AC contactors, frequency converters, converters, Explosion-proof electrical appliances and other medium-voltage and low-voltage electrical appliances; automotive industry and other fields. In the electrical and electrical industry: partitions, lining boards, arc extinguishing covers, arc extinguishing cylinders, arc extinguishing plates, arc extinguishing plates, terminal blocks, interphase insulation, bottom partitions, contact support parts for various switch cabinets; switches And transformer structural support, bus splint; signal board, electric furnace, electric furnace insulation. In motors and motors: motor electric drive components, movable cover plates, slot wedge stators, fixed gaskets, thin gaskets, carbon brush holders, etc.

GPO-red and white matte board series, mainly used in air gap sheets of electrical products such as special transformers, reactors, inverters, and reverse current devices; IGBT insulation supports have relatively strict requirements for thickness tolerances and reject temperature resistance levels. Insulation components with higher requirements; arc extinguishing chambers of high-voltage DC switchgear; and interlayer insulation parts of stacked bus bars
