SynTherm® – Insulating Materials

SynKraft® VSP H2

SynKraft® VSP H2 is a tear-proof, flexible 2-ply insulation consisting of a polyester film with special presspaper attached to one side.

Attributes

The pressboard displays good absorption of impregnants, resulting in exceptional bonding between all winding components after impregnating.
The polyester film improves the electrical and mechanical properties of the pressboard layer in the composite material, especially the resistance to tears, and provides excellent gliding properties for an automatic winding feed. On the other hand, the pressboard layer facing the laminated core is protected by the polyester film during processing.

Application

SynKraft® VSP H2 is used as an extremely costeffective slot insulation and slot closure in stators and rotors, especially for small motors, and is often applied as interlayer insulation and final insulation in small transformers.

Standards
  • Class B (130 °C) insulating material
  • Insulation according to IEC 60626
  • RoHS compliant according to 2011/65/EU
  • Test method IEC 60641-2
  • Sample conditioning acc. to standard atmosphere 23/50

It remains to be seen how things will continue. Crisis management dominates. It is simply impossible to make serious forecasts about future economic and social changes. All forecasts are plain guessing.

Thus, the resolutions remain: maximum solidarity, responsible action and best possible maintenance of all structures. There will be a time after SARS-CoV-2!

In this spirit we wish you all much steadfastness and good health.
