Single-sided service assembled chambers of KSO-366 series
Single-sided service assembled chambers of KSO-366 series (hereinafter KSO) are designed for equipping indoor switchgears rated at 6 or 10 kV (mainly urban distribution substations supplying residential buildings, commercial, administrative complexes, and small enterprises).
KSO are used as part of switchgears (RU) rated at 6 and 10 kV during; Complete switchgear cabinets of the KRU series comply with interstate standards GOST 14693, GOST 12.2.007.0, GOST 12.2.007.4, GOST R55190.
- new construction;
- expansion;
- reconstruction;
- technical re-equipment of the following facilities:
- distribution and transformer substations of urban power grids;
- distribution and transformer substations of civil and infrastructure facilities;
- distribution substations of industrial enterprises;
- traction substations of urban electric transport and subways;
- step-down substations 35-110/6-10 kV and 6-10/0.4 kV of distribution networks.
The popularity of using KSO chambers is due to the ease of their installation into switchgear directly on site. Thanks to the convenient dimensions of KSO chambers, it becomes possible to upgrade existing switchgears with them. The compact arrangement of components ensures easy maintenance, and due to the protective interlocking system of KSO chambers, personnel are reliably protected against potential electrical shocks.
