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.
