Cameras KSO with a roll-out element is a small-sized indoor switchgear in a metal arc-resistant casing with air insulation. The key element of the cell is a reliable vacuum circuit breaker. Modern switching devices, microprocessor relay protection and the structure of the case from functional compartments make it possible to create a cell with a high degree of safety and reliability.
KSO chambers with a withdrawable element are used in three-phase alternating current switchgears. They are installed as part of closed transformer substations at various facilities - at industrial, agricultural enterprises, at power plants, etc.
The use of a withdrawable element has a number of advantages over the stationary version:
- when the element is rolled out, a visible circuit break is created;
- the cells are more convenient to maintain, since it is easier for the personnel to access the internal equipment;
- reduced overall dimensions allow using cells in small premises;
- the ability to carry out repair and scheduled work separately with a switch, without removing voltage from the busbars of the cubicle.

The withdrawable cell element consists of a wheeled cart, which can be fixed in several positions, and metal structures with electrical equipment located on it (vacuum circuit breaker, busbars, support insulators etc.) The element is provided with an interlocking system that excludes improper actions of the service personnel.
Electrical equipment of this type is considered reliable and has a long resource of switching resistance.
