product description
Description of Epoxy Laminated Pipe
3640 epoxy fiberglass cloth laminated tube is tube-like laminated products, which is manufactured by fiberglass cloth impregnated with epoxy resin, and then rolled, baked and cured under heat and hot pressing with good dielectric property and strong machinability. The insulation class is B class and the main color is yellow.
Application of Epoxy Laminated Pipe
Can be used as insulating structural spares in electrical equipments, and also, can be processed into coil insulation cylinder of try-type transformer and insulation end coil of transformer.
Advantage of Epoxy Laminated Pipe
3640 epoxy fiberglass cloth laminated tube, produced by ZTelec Group using fiberglass cloth and epoxy resin as raw material, can be mass-produced with advanced production equipment and automatic production line. This product has the advantages of reliable quality, smooth appearance, uniform color, neat cutting ends and small thickness tolerance with strict manufacturing technology. Meanwhile, ZTelec Group is equipped with advanced ventilation facilities and dust-removing equipment to keep the products dry and clean. 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.
