product description
Description of Phenolic Cotton Cloth Rod
3723 phenolic cotton cloth laminated rod is one of insulating rods with circular cross-section, created by cotton cloth impregnated with phenolic resin under hot pressing of molding. It has higher mechanical strength, dielectric property and excellent Machinability. The insulation class is E class and the main color is coffee.
Application of Phenolic Cotton Cloth Rod
Apply to as insulating structural spares, screw processing parts and wear-resistant structural parts for mechanical equipments and can be used in humid condition and transformer oil.
Advantage of Phenolic Cotton Cloth Rod
3723 phenolic cotton cloth laminated rod, produced by ZTelec Group using phenolic resin as raw materials, can always maintain its structural integrity and dimensional stability even at extreme high temperature. Ztelec Group adopts advanced mechanical processing technology and this product has the advantages of smooth surface, neat cutting ends, uniform color and reliable quality. 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.
