SynTherm® – Insulating Materials SynTherm® AHA
SynTherm® AHA is a flexible 3-ply insulation consisting of a polyimide film with a calendered aramid paper layer on both sides.
The excellent electric and thermal properties of the polyimide film and the excellent mechanical and thermal properties of the outer aramid paper layers result in a high per-formance insulating material. The outer layers protect the polyimide film against hydrolysis influences and mechanical stress.
Application
SynTherm® AHA is used in electric motors with high performance ratio as slot and phase insulation or wedge. SynTherm® AHA can also be used as core, interlayer und final insulation for transformers when a very high temperature resistance at high mechanical load is requested.
Standards
- Temperature resistant up to 180 °C
Delivery forms
Total thickness in μm: 200, 300, 400
SynTherm® AHA is available:
- tapes as of 6 mm width
