Inductors, reactors and chokes are manufactured in vacuum impregnation or in vacuum pressure impregnation (VPI) technology, depending on the application. They are provided with air core or with iron core.
ABB's inductors are especially suitable for complex technical requirements:
- wide range of power ratings, from 1 kVAr to several MVAr
- single-phase or three-phase
- for voltages up to 36 kV
- special designs for high frequency applications (up to 25 kHz)
- with different types of cooling: AN (air natural), AF (air forced) or WF (water forced)
- with any type of enclosure
Applications: commutation, blocking, ac/dc filter, harmonic filter, line filter, capacitor protection, current limitation traditional and transformerless UPS, solar and wind energy, drives, inverters, power factor correction, special versions for rolling stock applications
