Paper Reinforced Phenolic Tube

Abstract:
Paper reinforced phenolic tube is hard tubular insulation laminate sheet that is made by insulating paper with one side coated by phenolic resin through drying and rolling. Optional model is 3520.

Performance and Applications:
3520 paper reinforced phenolic tube has relatively high dielectric performance and certain mechanical strength. It is suitable for insulation structural parts of electric equipment in dry conditions and transformer oil.
