6-10 кВ Assembling chambers of unilateral service, types КСО 393, 393В, 210, 298

6-10 кВ Assembling chambers of unilateral service, types КСО 393, 393В, 210, 298

КСО is assembled Camera of unilateral service is intended for use in electrical installations of three-phase AC 50Hz and 60Hz, 6kV and 10kV voltage, for systems with neutral insulated or grounded through arc suppression (Peterson) coil.
From КСО cameras going switchgear, serving for electricity reception and distribution. The principle of operation is determined by a set of circuits of main and auxiliary circuit cameras.
The climatic performance У and Т, accomodation category 3 as per GOST 15150.
The structure of КСО series includes a variety cameras of standard performance, differing by design, purpose and used sets of equipment.
