The 3520 Phenolic Resin Paper Tube has proven to be a vital material in the electrical insulation/industrial structural materials fields because of its superior overall properties. These tubes have been successfully employed in many applications, including motors, electrical apparatus, transformers, switchgear, as well as mechanical items, to provide effective insulation protection and mechanical support and an alternative to these traditional materials.

The creation of 3520 Phenolic Resin Paper Tubes begins with high-grade grade insulation paper that has been impregnated with the latest generation of advanced phenolic resins. After being wound into a tubular shape, they are subjected to the high temperature/high-pressure cure process resulting in the following advantages: a dense internal structure and a more consistent resin distribution throughout, thus yielding superior mechanical properties and providing stable electrical properties. The material exhibits durable and dependable performance under rigorous conditions consistently over time.

In terms of electrical performance characteristics, this phenolic tube is an outstanding insulator and prevents maximum electrical leakage and breakdown. High voltage and low voltage electrical application capabilities; excellent heat resistance for stable operation at elevated temperatures with no change in configuration or performance, making it ideally suited for demanding industrial applications.

The 3520 Phenolic Resin Paper Tube has excellent mechanical strength and rigidity, enabling it to endure external forces/pressure and mechanical shock without cracking or damaging. Furthermore, its ability to resist oil, solvents, and some chemical agents increases the life of the product in complicated work environments. Compared to traditional insulating materials, it provides a longer-lived life and superior performance in terms of safety.
