3640 Epoxy Phenolic Glass Tube for Electrical Insulation and Industrial Applications

Description

3640 epoxy phenolic laminated glass cloth tube is manufactured from non-alkali glass cloth impregnated with epoxy phenolic resin, and processed through hot rolling and baking to form a solid, roll-pressed laminated structure.

It offers a well-balanced combination of mechanical strength, heat resistance, and dielectric performance. The material is suitable for use as insulating structural components in electrical equipment and can operate reliably in humid environments as well as in transformer oil. Due to its stable overall performance and mature manufacturing process, 3640 tube is one of the most widely produced and commonly used laminated insulation tubes.
