GPO-3 rigid fiberglass reinforced composite laminate

GPO-3 profiles are made of high-strength glass fiber felt impregnated with unsaturated polyester paste, and then hot compression molded and pultruded. They are available in U-shaped, L-shaped, I-shaped, H-shaped, hat-shaped, square tube, and round tube. , bars and other shapes; we can also cut and drill parts of various shapes according to customer drawings. Our products have obtained US UL certification and ROHS report.

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 and added with corresponding additives and hot-pressed.

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 and added with corresponding additives and hot-pressed. GPO-3 insulation board, also known as UPGM-203, refers to the unsaturated polyester fiberglass felt board material, which is used for mechanical and electrical purposes. It has good electrical properties under high humidity and good mechanical properties under moderate temperatures. It is flame retardant and resistant to Excellent resistance to arc and leakage traces.

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 high quality insulators. According to the grade characteristics, it is widely used in electrical aspects in the field of engineering technology by taking advantage of its optimized special performance.

GPO-3 insulation board flame retardant performance

Grades 1580 and UTR are UL-rated V-0. Grade UTR does not contain halogens, and the system produces very little smoke and toxic fumes in the event of a fire.

Mechanical strength

High strength fiberglass reinforced polyester laminate will not shatter. Because of its isolating properties, rigid laminates provide structural support. Flexible laminates are available in applications with a minimum bend diameter of 19mm.

Heat resistance

Durostone ® Glastic ® laminate provides excellent protective properties and dimensional stability during heating. These laminates have UL temperature ratings in the 120-210°C electronic and 130-210°C mechanical ranges.

Easy to form

These materials can be easily processed using standard metal handling equipment. Can be stamped, drilled, machined, sheared and sanded. Grade UTR is well known in machining centers for its ease of molding at high speeds. Grade 1580 punches cleanly and quickly

GPO-3 insulation board application

Applications in circuit breakers: Frame circuit breakers: safety baffles, safety shutters, spacers, phase partitions, etc.

Applications in plastic case circuit breakers: phase partitions, arc extinguishing chamber arc partitions, etc.

Applications in electric motors: motor armature components, movable cover plates, wedge stators, fixed washers, thin washers, carbon brush holders, etc.

Applications in switchgear: front end, rear end, upper end, bottom end, phase partitions in partition systems, etc. Other applications: arc-resistant structural parts

GPO-3 profile features:

1. Good flame retardancy (94UL V0 level)

2. Good arc resistance (182 seconds)

3. Good resistance to leakage traces (CTI>600V)

4. The heat resistance grade reaches F grade (above 160℃)

5. Outstanding electrical performance and high load-to-strength ratio

6. It has good thermal mechanical strength and can maintain good mechanical and electrical properties under continuous heating conditions.

7. High space temperature resistance and excellent machining performance

GPO-3 profile application:

1. Busbar insulation grooves and insulation angles for power control and power transmission and distribution equipment are used in wire troughs, cable culverts, cable routing racks, insulation grooves, fuse chucks, end insulation, cable brackets, busbar brackets, stiffening angles, and cores. Corners and insulating corners form the base (erection) and terminal board.

2. High-voltage speed regulating device and high-voltage soft start: insulating bracket in the power unit

3. Transformer: Transformer components, ventilation and heat dissipation rods, core corner insulation between the core and coil, tough heat-resistant terminal board composed of corner insulation, etc.
