GPO-3 insulation board is also known as GPO-3 laminate. It is a hard plate-shaped insulation material made of alkali-free glass fiber felt board impregnated with unsaturated polyester resin paste and added with corresponding additives through hot pressing. GPO-3 insulation board, also known as UPGM-203, refers to unsaturated polyester glass fiber felt board material, which is used for mechanical and electrical purposes. It has good electrical properties under high humidity, good mechanical properties under medium temperature, flame retardancy, good arc resistance and good resistance to leakage traces.

Transformer is a static electrical device used to transform AC voltage and current to transmit AC power. It realizes power transmission based on the principle of electromagnetic induction. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers according to their uses: power transformers are necessary equipment for power transmission and distribution, and power distribution to power users; test transformers are equipment for withstand voltage (boost) tests on electrical equipment; instrument transformers are used for electrical measurement and relay protection of distribution systems (PT, CT); special-purpose transformers include smelting furnace transformers, welding transformers, electrolysis rectifier transformers, small voltage regulating transformers, etc.

In motors, motor armature parts, movable covers, fixed gaskets, thin gaskets, carbon brush holders, etc. are generally machined using GPO-3 insulating plates.
