Phenolic paper laminated tube Your location:home > Products

  Phenolic paper laminated tube is formed by hot rolling,baking electrical insulating rolling paper or insulating craft impregnated with phenolic resin under heat and pressure. The Insulation tube can be processed into all kinds of insulation parts, The products are widely used transformers, electric motors, cabinets, control boxes, electric switches, household appliances, railway, automobile, computer and medical appliance,etc.  
   Grade X tubes:high mechanical strength and fair electrical strength under dry condition,discretion should be use when high humidity conditions may be encountered.
  Grade XX tubes:Good machining and threading qualities and fair qunching,not as strong mechanically as grade X rolled tubes,but better in moisture resistance,with lower dielectric losses,particularly on exposure to high humidity.
