Single-end service assembled chambers KSO-366, 393.
Purpose.
KSO-366,393 are used to work in electric plants with supply voltage 6 and 10 kV and three-phase current with current frequency 50 and 60 Hz and voltage 6 (10) kV for systems insulated or grounded neutral point by arcing ground suppressor.
Chambers are different by schemes and equipments of primary and secondary circuits.
