product information

Product name: FZW28-12 outdoor demarcation vacuum load switch

Category: high voltage components

Product introduction: FZW28-12 series outdoor vacuum load switch is suitable for outdoor three-phase AC power distribution system with rated voltage of 12kV and rated frequency of 50Hz. It is used for opening and closing load current and closing short-circuit current.

Overview of FZW28-12 Outdoor Boundary Vacuum Load Switch

The FZW28-12 series of outdoor vacuum load switches are suitable for outdoor three-phase AC power distribution systems with a rated voltage of 12kV and a rated frequency of 50Hz. They are used to open and close load currents and close short-circuit currents.

It is suitable for substations, industrial and mining enterprises, cities and clothing networks as protection cities, rural power distribution networks, and places with frequent operations.

The boundary load switch consists of two parts, the FZW28-12 vacuum load switch and the controller, which are electrically connected through aviation sockets and outdoor sealed control cables. It can reliably judge the milliampere zero-sequence current and phase-to-phase interruption current inside and outside the detection range, and can be suitable for power distribution systems with different neutral point grounding methods.
