3640 Epoxy Fiberglass Laminated Insulation Tube

The Epoxy Fiberglass Laminated Insulation Tube 3640 is engineered from premium alkali-free glass cloth, thoroughly impregnated with a high-performance epoxy phenolic resin. It is manufactured through a controlled process of hot rolling, followed by precise baking and thermal curing. This ensures a dense, homogeneous tubular structure with excellent dimensional stability.

Characteristics of Epoxy Glass Insulation Tubes:

This industrial-grade tube delivers an exceptional balance of critical properties. It possesses extremely high mechanical strength, excellent dielectric (electrical insulation) characteristics, and reliable heat resistance, meeting the standards for Class F insulation (155°C). 

The tube features a smooth surface with a consistent yellow color, cleanly cut ends, and minimal thickness tolerance. It also offers strong machinability, enabling it to be cleanly drilled, turned, or cut into specific components without fraying or delamination.

Applications of Epoxyglass  Insulation Tubes:

Designed for demanding electrical and mechanical environments, this laminated tube is a critical structural insulation component. Its primary uses include:

• Insulation in Transformers: It is extensively used to fabricate key insulating parts, such as: Coil Insulation Cylinders/Barrels for dry-type transformers. Insulation End Rings/Collars that provide durable mechanical and dielectric protection at coil ends.

• Electrical Equipment Insulation: It serves as a reliable insulating structural spare part in various high-voltage and general electrical apparatus

• Material of Choice: It is the preferred solution for applications requiring guaranteed long-term dielectric integrity, structural robustness, and thermal stability.
