SynTherm® – Insulating Materials SynKraft® KP
SynKraft® KP is a tear resistant, flexible 2-layer insulation made of one layer polyester film and high-compressed pressboard.
The pressboard absorbs impregnants easily and ensures excellent bonding of all winding components after impregnation. The polyester film improves the electrical and mechanical properties of the pressboard layer of the laminate, in particular the tear resistance, and provides good slip during insertion of windings. The pressboard layer protects the polyester film from damages caused by the lamination stack during processing.
Application
SynKraft® KP is a very economic slot liner and slot closure in stators and rotors and is also used as layer insulation and covering insulation in small transformers.
