Product Description
ZW8-12 series outdoor high-voltage vacuum circuit breaker is a kind of three-phase outdoor high-voltage switchgear of rated voltage 12kV and AC 50Hz.
Its population structure is three-phase together box type. Three-phase vacuum arc-extinguish chamber palaces in a metal cabinet, using the SMC insulating material to insulate inter-phase and phase to earth, which is reliable in performance and high in insulating intensity.
ZW8-12G is combined with ZW8-12 circuit breaker and isolating sword, called combination circuit breaker and used as a section switch.
3-phase AC 50Hz outdoor high voltage distribution equipment
Used for opening and closing loading, over-loading and short-circuit current
With computer remote control system and data wireless transmission terminal and more
Remote opening and closing function can be achieved
This is the optimum unboiled equipment for remaking the town and country's electric net
