BOPP Film (Dielectric Film in High Voltage Power Capacitor)

Application:
DDN supplies BOPP capacitor films for high voltage power capacitor manufacturing enterprises. These films are suitable for HV, EHV, and UHV power and transmission applications in any country. The voltage range of our capacitor films is -1100KV~1100KV. The thickness of these BOPP films ranges from 6um to 23um.

Size Parameter:
Thickness: 6~23μm
Width: 30mm~920mm
External diameter of film roll (mm): ≤300
Internal diameter of film roll core (mm): 76
The BOPP film meets the requirements of IEC standards and GB standards.
