GPO3 Insulation Board Use Standard

GPO3 insulation board use standard

GPO3 insulating board is a kind of molding material with high mechanical strength and excellent insulating property. It is widely used in electric power, electronics, transportation, metallurgy and other fields, and is an ideal electrical insulation material.

The material of GPO3 insulating board is glass fiber reinforced unsaturated polyester resin, with smooth surface, uniform color, high mechanical strength, good impact resistance, good heat resistance, excellent insulating properties, good weather resistance and chemical resistance. In the process of use, it needs to be used in strict accordance with the following standards.

Appearance and size:

The size and shape of GPO3 insulating board should be consistent with the design drawings, the surface should be flat, no bubbles, cracks and foreign objects and other defects, if defective, it should be replaced.

Physical properties:

The hardness of GPO3 insulating board should be in accordance with ASTM D2583 standard, and the difference of hardness should not be greater than the range specified in the standard; density should be in accordance with ASTM D792 standard and the difference should not be greater than the range specified in the standard.

Mechanical properties:

The mechanical properties of GPO3 insulating board are divided into three aspects: tensile, bending and impact. Tensile properties should be in line with ASTM D638 standards, and the ratio between tensile strength and elongation should not be less than the standard requirements; bending properties should be in line with ASTM D790 standards, and the bending strength and modulus should be in line with the standard requirements; impact properties should be in line with ASTM D256 standards, and the absorption energy should be in line with the standard requirements.

Electrical properties

Thermal stability:

The thermal stability of GPO3 insulating board should be in accordance with ASTM D2307 standard, and should meet the requirements of the standard.

Application scope:

GPO3 insulating board is suitable for electrical equipment, dry-type transformers, control cabinets, generators, cable bridges, power generation equipment and other occasions requiring insulation.

GPO-3 Insulation Board Detailed Application Scope

GPO-3 is a rigid board insulating material with excellent performance. Its processing technology is mainly unsaturated polyester resin paste soaked alkali-free glass fiber mat board, made by hot press molding and pultrusion molding process, can be processed into U-type, L-type, I-type, H-type and other shapes.

GPO-3 insulation board detailed application scope explained: gpo3 is a widely used insulation material, which is inseparable from its own performance characteristics. It has good heat resistance, can work normally at a high temperature of 160 degrees Celsius, can achieve more than 180 seconds of arc resistance and 600 volts of leakage trace resistance, has excellent electrical properties, can withstand a certain degree of high load strength, and can be warmed up at the same time to maintain good mechanical processing and electrical properties, is a good and cost-effective insulating board.

GPO-3 profile is also widely used. Insulated supports should be used for high-voltage speed control devices and high-voltage soft-start power units. Or a tough heat-resistant terminal board consisting of transformer assembly, ventilated cooling rod, core angle insulation between core and coil, and corner insulation. In addition, it can be processed into busbar insulated troughs and insulated corners for power control and transmission and distribution equipment, and applied to wire ducts, cable culverts, cable racks, insulated troughs, fuse clips, end insulations, cable holders, busbar holders, stiffening corners, core corners, and insulated corners, to form bases (racking) and terminal boards

Precautions:

When using GPO3 insulating board, attention should be paid to avoid the accumulation of static electricity, avoid friction and collision with sharp objects, keep its surface clean, and avoid contact with organic acids, sulfuric acid and softeners and other chemicals.

In short, the use of GPO3 insulating board is very strict standards, in the process of use, you need to strictly follow the standard operation, to ensure that it has excellent electrical insulation properties and mechanical strength, so as to ensure the safety and reliability of the equipment in the process of work.
