Phenolic cotton cloth laminated sheet Your location:home > Products

  Phenolic cotton cloth laminated sheet is made of cotton cloth impregnated phenolic resin by processing under heat and pressure. Phenolic cloth sheet 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.   
   3025 sheet: High mechanical applications, suitable for using as insulation structural parts of machinery and electric equipments that require high electrical properties., available in transformer oil.
  3025B sheet, 3025C sheet are similar to 3025, but with lower properties.
  3026 sheet: High mechanical applications, suitable for mechanical equipment in operation, anti-seismic components. suitable for using as insulation structural parts of machinery and electric equipments that require high electrical properties.
  3027 sheet: High electrical applications, suitable for using as insulation structural parts of machinery and electric equipments that require high electrical properties. available in transformer oil.
