FZW28-12OUTDOOR BOUNDARY VACUUM LOAD SWITCH
Product Overview
FZW28-12 series outdoor boundary vacuum load switch is suitable for outdoor three-phase AC power distribution system with rated voltage of 12kV and rated frequency of 50Hz, and is used for opening and closing load current and closing short-circuit current.
FZW28-12 series outdoor boundary vacuum load switches are suitable for substations, industrial and mining enterprises, urban and rural power grids for protection and control, and urban and rural power automatic distribution networks and places with frequent operations.
FZW28-12 series outdoor boundary vacuum load switch is used as an operation control switch for overhead line power distribution system. There are many types. It has outstanding advantages such as oil-free, simple structure, reliable performance and no maintenance. It has been widely used so far. This product is combined with FDR type fault detector or RTU remote control terminal device and other equipment to form a distribution automation system with a very simple structure, which can realize automatic location of overhead line faults and automatic isolation of fault sections. In order to update the existing power distribution switchgear in our country, it is necessary to realize the transformation of the power distribution equipment characterized by oil-free and automation
