Pressboard

Due to its high chemical purity, this presspan is particularly suited as:

  • Insulation material in power transformers

  • Insulation material in distribution transformers

  • Pressspan is a special product on the basis of the purest wood cellulose fibres. Without additional binding agents, these are made up into a fibrous web and then pressed. Due to its high chemical purity, presspan is particularly suited as an insulating material in electric machines, capacitors, etc., and especially in oil-cooled transformers.
  • Insulation class A (105 °C) according to VDE 0530 part 1
  • Proven insulating material on cellulose basis
  • Material properties and the procedures for testing and inspection are defined in IEC 641.
  • Good compatibility with liquid dielectrics
  • High dielectric strength
