SynTherm® – Insulating Materials SynKraft® EP grained
SynKraft® EP is a grained 2-layer insulation constructed from polyester film with high grade press board on one side. This composite material is suitable for class B (130 °C).
By stamping the press board the material achives a good suppleness and extensibility. At the same time it maintains its stability.
The minimum stability is required for in-serting the phase insulation between the windings. The suppleness allows protection against mechanical stress on deformation of the end of turns.
Application
Mainly as phase insulation in stators.
Delivery forms
Original rolls with approx. 600 mm width or slit rolls
