Unilateral maintenance collection chambers of KSO-366 and KSO-386 series
KSO-366 and KSO-386 series chambers as well as bus bridges are intended for furnishing a set of switchgears for 6(10) kV voltage of three-phase AC with 50 Hz commercial frequency in systems with an insulated neutral. The principle of their operation is conditioned by the aggregate of chambers’ main and auxiliary circuit diagrams. This type of chambers represents a metal construction assembled from rolled-formed sheets. The main circuit gear is placed inside the chamber. The actuators and control gears are on the front of the chamber.
