Products Description
Epoxy Laminated Glass Cloth Rod is a solid rod-shaped insulating material made of glass cloth impregnated with epoxy resin and cured by lamination, heating, molding or pultrusion. It combines the excellent electrical properties of epoxy resin and the high-strength structure of glass cloth, and is widely used in industrial fields such as power equipment, transformers, motors, and high-voltage switches.
Size of Laminated Rod: diameter 8-200mm, length 1,000mm
