Mutipart cells of unilateral service of KSO 399 series and busbar bridges to them are intended for bundling of distributing devices and standard substations with alternating current voltage of 6 or 10 kV, frequency of the systems with the isolated neutral of 50 Hz, installed in the areas with a temperate climate inside the premises (from-25°С up to +40°С).

Switchboard panels SO-99 are intended for reception and distribution of electric power of a three-phase alternating current, with frequency of 50 Hz at a voltage up to 0,66 kV and for departing lines protection against overloads and currents of short circuit. SO-99 are intended for work at temperature of air from -25°С up to +40°С.

Complete transformers substations KTP 1,2 of blind and leading-through types, with the capacity of 40, 63, 100, 160, 250, 400, 630 kWatt, with the voltage of ВН of 6 or 10 kV, with the voltage of НН 0,4 kV are intended for reception, transformation and distribution of electric power of a three-phase alternating current with frequency of 50 Hz in the systems with a dead-grounded neutral of the transformer on the lowest voltage side.

Complete transformer substations of blind and leading-through types KPTGSM with the capacity of 100, 160, 250, 400, 630, 1000 kWatt, with the voltage of ВН of 6 or 10 kV, with the voltage of НН 0,4 kV, with the frequency of 50 Hz, are intended for reception, transformation and distribution of electric power in one-two beam and loopback electrosupply circuits of the city power circuit in the areas with a temperate climate (from-45°С up to +40°С).

Complete transformer substations KTP with the capacity 10-250 kWatt of a three-phase alternating current of frequency of 50 Hz and voltage of 6-10\0,4 kV are one-transformer substations of blind type of the outdoor setting and they are used for electrosupply of the agricultural consumers, separate settlements and small industrial targets in the areas with a temperate climate (from -45°С up to +40°С).

The load interrupter of VN-RA-000 type belongs to the switching devices supplied with the autogas arc-suppressing device. The interrupter is intended for switching under loading of circuits of a three-phase current of frequency 50 Hz of rated voltage up to 10 kV, rated current 400, 630, 800 ampere, with the grounded or isolated neutral.

The high-voltage three-polar disconnectors of RV-10/630, 1000, 1600 UZ types are intended for switching-off and switching-on under the voltage of sites of the electric circuit of a high voltage at absence of a loading current or for change of the connection circuit, for safe works on the switched-off site and under the certain conditions, for switching-off and switching-on the charging currents of air-lines and the no-load current of transformers.
