KSO cameras are used to complete switchgears.

2 year warranty
Prefabricated chambers of unilateral service (KSO) are intended for completing switchgears of alternating three-phase current with a frequency of 50 Hz for systems with isolated neutral.
KSO are used to complete transformer substations as part of urban power grids, at industrial, agricultural facilities, at construction sites.
KSO is a prefabricated metal structure. Unlike switchgear, supplied in closed cabinets, KSO busbars are laid openly, on top of the chamber.
КСО are installed in closed rooms of switchgears.
Switchgears assembled from KSO chambers are equipped with load switches, vacuum switches, disconnectors with earthing knives, voltage and current transformers, automatic relays, measuring instruments, counters, microprocessor units and other devices.
Protective automation can be implemented both on electromechanical relays and using microprocessors.
When designing, the completeness of CSR is selected in accordance with the requirements of the customer.
KSO cameras of the third series (393, 366) differ from KSO of the second series (292, 298) only in overall dimensions.

Features:
- the possibility of manufacturing CSR of different sizes in accordance with the technical requirements of the customer;
- the system of built-in locks increases the safety of CSR operation;
- ease of installation and commissioning thanks to easy access to the fixing points of the cubicles, busbar and cable connections;
- if relay protection is implemented on microprocessor units, KSO cameras allow integrating the RU into automated control and accounting systems.
