Phenolic paper laminated tubes Your location:home > Products

  Phenolic paper laminated tubes(insulation tube,laminate tube,phenolic paper tube)are 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.

  PFCP21 tube: With mechanical and electrical application, moisture-resistance, primarily intended for mechanical and low electrical applications, suitable as structural parts of mechanical and electrical equipments.
  PFCP22 tube: With good electrical applications and high electrical application in oil, primarily intended for high electrical applications, suitable as structural parts of high electrical equipments.
  PFCP23 tube: Similar to PFCP21, good moisture-resistance, primarily intended for mechanical and electrical applications, suitable for structural parts of electrical equipments in high humidity conditions.
  3520 tube: Good electrical applications in dry conditions, suitable for structural parts of electrical equipments in dry conditions and transformer oil.
