product description
Description of Epoxy Rod
Epoxy resin fiberglass cloth laminated rod is one of insulating rods with circular cross-section, created by fiberglass cloth impregnated with epoxy resin under hot pressing of molding. It has higher mechanical strength, dielectric property and excellent Machinability. The insulation class is F class and the main color is yellow.
Application of Epoxy Rod
Apply to as insulating structural components, screw processing parts in electrical equipments and can be used in humid condition and transformer oil.
Advantage of Epoxy Rod
Epoxy resin fiberglass cloth laminated rod, produced by ZTelec Group using epoxy resin as raw materials, can be mass-produced with advanced production equipment and automatic production line. This product has the advantages of reliable quality, uniform appearance and color, and small thickness tolerance with strict manufacturing technology. The mechanical and electrical properties of products are superior to the similar one of other companies. Its quality is recognized by domestic and foreign large enterprises such as Lens Technology in China and Schneider Electric and sold overseas such as European and American areas.
