General:
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.
The CB is hermetical sealed, and is moisture-resistant, anti-condensation. It is especially suitable for application
at severe cold and damp areas.
Three-phase pillar and current transformer apply imported outdoor epoxy resin solid insulation materials. It is
high/low temperature resistant, UV-resistant and anti-ageing.
The operating mechanism is miniature spring operating mechanism with low breaking/closing energy
consumption.
The driving of it applies straight transmission with little components and high reliability. The operating
mechanism is enclosed in a cabinet, and that makes it rust-resistant and more reliable.
The CBS are electrically and remote controlled, also can be manually controlled. They can be fitted with
controllers to realize electric automation or to form auto-reclosing device with reclosing controller.
They are also fitted with disconnectors of clear isolation opening and have reliable mal-operation prevention
mechanical interlocking device between CBS. And the disconnectors are easily detachable.
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)
