XCR Corona Polyimide Film

 

Product Description:

CR polyimide film was developed specifically to withstand the damaging effects of "corona",which can cause ionization and eventual breakdown of an insulation material or system when the voltage stress reaches a critical level.

CR polyimide film preserves the physical, mechanical property of polyimide film as it does, as well as the outstanding corona-resistant property, aiming at high power frequency control motor insulation.

It is produced with adopting advanced dispersion technique which put the inorganic nano-particles into the film, so it can improve the performance of corona-resistant corrosion dramaticlly.

Characters:
*Possessing 50 times ageing-resistance property  
*Halogen-free, environment-friendly, flame-retardant

 

Thickness available:25um 38um 50um
 

Application:
*Wind power generator, variable frequency motor, traction motors, and electrical rotating machines
*High voltage transformer
*Magnetic wire wrap
*Super high-voltage cable insulation
*Other electronic insulation

 

 

Property:

NO.
