Specification:
ZW32-12 type outdoor pole-mounted HV vacuum CB (hereinafter referred to as CB) is rated voltage12kV, 50Hz three-phase AC outdoor power distribution equipment used for power distribution network to break and close load current, over-load current and short-circuit current in electric systems. It is used in substation and industrial & mining enterprise power distribution system for protection and control, better fits countryside power grid and frequent operation places, especially for the retrofit of urban power network and countryside power network. Characteristic:
The CB applies three-phase pole-type structure. It has characteristics of stable closing/breaking property, no fire or explosion danger, maintenance-free, small dimension, small weight, long service life, etc.
CBS can be fitted with two-phase or three-phase current transformers for automatic over-current release and supplying circuit information for intelligent controller.
Weight of CB<100kg
Overall dimension: H× W× D 740x960x880 (with isolation) 720x900x240 (without isolation)
