1. Main applications
The LG type over voltage absorber can absorb mainly the over voltage when turn on the Vacuums which and contactor, so that to protect electric motor and their insnlations.
2. Structure of product
The LG type over voltage absorber uses super quality and high performance ins usation material as solid medium, with the unique high vacuum vaporation tech nology forming metal layer as the spelified electric pole strucuruce.
The capacitor cells are fabricated by antomatic winder, then made up capacitor by intorduced technology, series connected with acustornbuild non-induction resitance combined the R-C voltage absorber, sealed in antiflame insulation case to form the three-phase or sigle-plase over voltage absorber.
3. Main feature
3.1 R -C over voltage absorber is made of non-induction vesistance and dry H.V capacitor, it has small volume, light weight, no oil structure can avoid the ambient pollution.
3.2 Good protection than MOV, it can absorb steeply wave of over voltage.
