Chambers of KSO-2009 series
KSO-2009 series unilateral-maintenance collection chambers with a voltage of 6(10) kV are designed for integration of three-phase AC switchgears of 6(10) kV voltage and 50 Hz commercial frequency of systems with an insulated neutral or a neutral earthed through an arcing ground suppressor.
KSO-2009 series chambers are completed with a small-sized vacuum switch Evolis, VVU-SESch (“Electroschield TM-Samara” Group of Companies), and VVM-SESch types.
