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.
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.
