High voltage switchgear
L/CT/T
CHSIS-12C(V) solid insulated metal switchgear is suitable for 6 ~ 12kV three-phase AC 50 Hz power system, such as loop network power supply, medium and small capacity distribution room, double circuit power supply and primary distribution of cable feeding network.Compared with the traditional SF6 ring main unit, it has a new generation of ring network switchgear with more reliable, more environmental protection and wider application range.(can be expanded to intelligent devices).
