Unilateral maintenance collection chambers of KSO-298 series
KSO-298 series chambers with 6(10) kV voltage are intended for furnishing a set of 50 Hz commercial frequency three-phase AC switchgears of systems with an insulated neutral or a neutral earthed through a ground-fault neutralizer.
The chambers are completed with small-sized vacuum switches of VVU-SEShch, BB/TEL, and VVM-SEShch types.
