3520 Phenolic Paper Laminated Tube

Color: dark yellow  

Size

I. Define and purpose

This laminated product is formed through heat pressing after electric industry alkali glass cloth dips into the phenolic resin. It has high mechanic and dielectric performance, and applicable as insulation structural components for electromechanical/electrical equipment, as well as used under damp environmental conditions and transformer oil. Heating resistance rate is Grade E.

II.Technical requirement for surface

Appearance: The surface should be smooth. Layers, arris and bubbles are not allowed. Tiny corrugation and trimming signs are allowed. Little impurity that will not affect its voltage resistance is allowed, such as irregular color, scratch and glue marks. Tiny corrugation in the inner wall is allowed. The end shall be cut tidy. The tubes with over 13mm wall thickness are allowed to have tiny flaws on the end.

III.Characteristics

♦ High mechanical properties, and oil resistance and certain dielectric property.

♦ Temperature resistance: 120 °C,Heating Resistance: Grade E

♦ Withstand a variety of chemical solvents and acid erosion

VI. Application

Chemical machine parts , general machine parts and gear ,and generators, pads, base, baffle etc..Generator ,transformer, fixture, inverter, motor and electric insulation component.
