SynTherm® – Insulating Materials Kapton® CRC polyimide film
Kapton® CRC is a polyimide film specially developed for the effects of partial discharge which may cause ionisation and possible losses of insulating materials.
Kapton® CRC combines the excellent features of Kapton® HN polyimide film with the advantages of a very glow-discharge resistant surface. Using a Kapton® CRC polyimide film improves the resistance of the insulating systems of high-voltage generators or motors significantly.
Application
- rotating electrical machines
- electrical insulation isolation
- generators
- traction motors
- transformers
- insulation of profile conductors and cables – specially in electrically highly utilized systems
Standards
- UL liste, File Number E 39505
