Single-end service assembled chamber of KSO 207V series.

KSO 207V single-end service assembled chamber is designed to receive and distribute electric power in electrical facilities with three-phase 50 or 60 Hz alternating current, 6 or 10 kV voltages and with insulated neutral or neutral with Peterson-coil and made according with BKGI.674712.002 TY specification (.674712.002 ).

KSO switchgear are made for domestic use as well as for export and can be used as 6-10 kV switchgear (including installment in modular building) designed to receive and distribute electric power in industry, agriculture, electrical station and substation for railroad electrification.

Operational principal is defined by arrangements of main and auxiliary circuitries.

KSO switchgears can be used as high voltage devices for complex transformer substations of KTP-10/0,4 (-10/0,4) and BMKTP-10/0,4 (-10/0,4) series with power from 100 to 2500 kVA.

Climatic versions are Y(moderate) or T(warm), and area class is 3 according to GOST 15150-69.
