Product Description

Product Description

3841 Fiberglass epoxy laminated rod is made of alkali-free glass cloth which shall be first soaked in epoxy resin, and then get hot-pressed by a forming mold into a rod with round section. It has good mechanical, dielectric properties, and excellent machinability. The insulation rods are suitable for long-lasting gears, transformers, electric motors, cabinets, control boxes, electric switches,  household appliances, railway, automobile, computer with the advantages of quieter and more economical than metal parts. Besides, it can also be used under moist conditions and in the transformer oil.
