Description
Series KSO-313SF switchgear of unilateral maintenance, with load-breaking switch in SF6 insulation are designed for switching of 3-phase, 50 Hz, 6, 10 kV rated voltage and up to 1000 A rated current circuits with neutral insulated or earthed via resistor or via an arc-suppression coil.
KSO-313SF switchgear devices are used to assembly switchgear RP (KRU) for receipt and distribution of electric power. The KSO switchgear operation principle is determined by an aggregate of circuits of the main and auxiliary circuits.
