Phenolic paper laminated tube is made of insulating winding paper or insulating impregnated paper impregnated with phenolic resin, heated and pressed, baked and cured.
Phenolic paper based tubing has been used for electrical insulation since the early 20th century. The combination of the high-temperature resistant phenolic resin and a treated paper convolute wound tube provides excellent strength, weather resistance and electrical resistance. Phenolic paper-based tubing has been used extensively through the years in various applications and parts in switch gear, transformers, tap changers, munitions, rockets, bushings, sleeves, coil forms, core tubes and casings.
Phenolic tubes can be used for insulating washers, carrying electrical wiring or switchboard panels and they can be threaded, tapped, drilled or machined with equipment for wood or soft metals.
