Insulated paper tube

Insulated paper tube is an important industrial insulation material, mainly made of cellulose paper or cotton fiber paper impregnated with resin, wound and thermally cured to form. Its core characteristics are good electrical insulation performance, high mechanical strength, and heat resistance.

Mainly classified by material, there are epoxy paper tubes, phenolic paper tubes, etc; There are circular tubes, square tubes, and irregular tubes according to their shapes. It is widely used in coil skeletons, insulation supports, and sleeves of electrical equipment such as motors, transformers, and relays, serving to isolate conductive components, fix coils, and dissipate heat. Its reliable performance and low cost make it a fundamental component in the field of electrical engineering.
