|---|---|
The FZW28-12F/(VSP5) Outdoor Boundary Vacuum Load Break Switch is specially designed for 12kV, 50Hz three-phase AC outdoor power distribution systems. It is used for switching load currents and making short-circuit currents.
This product is composed of two main parts:
FZW28-12 Vacuum Load Break Switch
Intelligent Controller
The two parts are electrically connected through aviation plugs and outdoor sealed control cables. It is capable of reliably detecting zero-sequence currents and inter-phase currents, making it suitable for power distribution systems with different neutral grounding methods.
Substations for distribution line protection and switching
Industrial enterprises for load control and fault isolation
Urban and rural power grids for automated distribution networks
Feeder automation systems (FA) requiring frequent operations
Protection and sectionalizing in medium-voltage distribution networks
12kV Rated Voltage – Designed for medium-voltage distribution networks.
Vacuum Interruption Technology – Ensures high reliability and long service life.
Integrated Intelligent Controller – Provides monitoring, detection, and automation functions.
Boundary Switching Function – Accurately detects currents inside and outside the section.
Adaptable to Grounding Methods – Suitable for different neutral grounding systems.
Compact & Durable Design – Resistant to harsh outdoor environments.
Automation Ready – Supports distribution network automation applications.
Ambient Temperature: -30℃ ~ +60℃
Altitude: ≤3000m (higher altitudes require insulation level adjustments)
Seismic Intensity: ≤8 degrees
Relative Humidity: Daily average ≤95%, monthly average ≤90%
Environment: Free from fire, explosion, severe pollution, chemical corrosion, or strong vibrations
