KSO-298

Prefabricated single-sided service cubicles

Single-sided service cubicles for 6–10 kV switchgear: installed in a row against a wall, with drives and relay equipment on the front. The cubicles take vacuum circuit breakers, load-break switches or disconnectors with earthing switches, depending on the connection scheme. In the photo: assembled rows of KSO cubicles in the BIONIKA workshop — relay compartments, drives, busbars behind a mesh guard.
