CS 24/36 is a series of outside-operated compact secondary substations for up to 36 kV volts.
These series are designed and manufactured by KTC to withstand different operating requirements and various environmental conditions.

The unit is a fully-equipped package substation that includes outdoor housing, medium voltage switchgear, distribution transformer, low voltage panel, and internal wiring for lighting on all compartments. As such, only the incoming cables need to be connected at the site and the site works are kept to an absolute minimum.
