Classified by application scenarios, voltage levels, structural features and opening capacity, all these products are strictly manufactured in our own factory to ensure stable quality.
1. Classification by Voltage Level
- 0.66kV-12kV: Most widely used, applied in outdoor low-voltage distribution (rural power grids, residential areas, small industrial areas). Features miniaturization, light weight and easy installation, with the largest annual output in outdoor series.
- 24kV-36kV: Suitable for medium-voltage outdoor power systems (urban suburban grids, industrial park outdoor stations, rural grid upgrading). Strong anti-interference, adaptable to moderate temperature difference and humidity changes.
2. Classification by Application Scenario
- Outdoor Power Grid Type: For outdoor power transmission/distribution (rural, urban grids). Anti-ultraviolet, anti-aging and anti-condensation, stable in high/low temperature, rain, snow and strong wind.
- Industrial Outdoor Type: For industrial outdoor distribution (metallurgy, petroleum, mines, railways). Corrosion-resistant shell and enhanced sealing, resisting dust, corrosive gas and large temperature difference.
All Sunway Hanguang Vacuum Interrupter For Outdoor VCB adopt core one-time brazing and pressure tank leak detection to reduce air leakage. With anti-aging, anti-corrosion and anti-condensation structures, they adapt to harsh outdoor environments.
