Dry-type inductors and chokes
Dry-type inductors and chokes are manufactured in vacuum impregnation or in vacuum pressure impregnation (VPI) technology, depending on the application. They are provided with an air core or an iron core.
Applications:
- Commutation
- Blocking
- AC/DC filter
- Harmonic filter
- Line filter
- Capacitor protection
- Current limitations: traditional and transformerless UPS
- Solar and wind energy
- Drives
- Inverters
- Power factor correction
- Special versions for rolling stock applications
Product scope:
- Wide range of power ratings, from 1 kVAr to several MVAr
