Switchgears of KSV 10 series.

KSV 10 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. KSV-10 can be used in industrial and atomic power facilities and is made according to technical terms BKGI.674551.063TY.

KSV 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 industrial grid, power station and substation. Operational principal is defined by arrangements of main and auxiliary circuitries.

KSV switchgears can be used as high voltage devices for complex transformer substations.

Climatic version is YXL3, atmospheric type is II and storage conditions are 1(L) according to GOST 15150.
