High-Speed Fault Clearing for Transmission Networks
Our Outdoor SF6 Circuit Breaker handles critical protection duties in high-voltage grids. This unit covers voltage levels from 33kV to 252kV. It uses SF6 gas as both the arc-quenching and insulating medium. This gas provides exceptional arc-extinguishing capability and insulation strength. The breaker responds rapidly to fault commands. Standard operating cycle is O-0.3s-CO-180s-CO. This means the breaker can perform fast auto-reclosing in very short time. This capability improves power supply reliability significantly. The housing uses high-strength aluminum alloy material. This gives excellent corrosion resistance and sealing performance. SF6 rated pressure is 0.6MPa. This pressure maintains stable insulation under both high and low temperatures. Our design and manufacturing processes follow strict power industry standards. We have invested strong R&D capabilities in this product. Our engineering team has deep experience in high-voltage equipment development. As a State Grid supplier, we understand grid safety requirements thoroughly.
Multiple Ratings for Different Grid Capacities
This Outdoor SF6 Circuit Breaker offers three rated current levels. You can choose 2000A, 3150A, or 4000A. Short-circuit breaking capacity comes in 31.5kA, 40kA, and 50kA options. You can select the best match for your grid's short-circuit level. This flexibility prevents oversizing or undersizing. The breaker uses spring or hydraulic operating mechanisms. Both mechanisms offer reliable operation and fast response. Spring mechanisms work well for most applications. Hydraulic mechanisms provide higher operating power for extreme conditions. The breaker's operating mechanism undergoes careful adjustment during production. We test opening and closing speeds to meet design targets. We also check SF6 gas tightness to prevent leakage. Main circuit resistance measurement confirms good electrical connections. Power frequency withstand voltage tests verify insulation integrity.
Export-Ready with Professional Packaging
Our Outdoor SF6 Circuit Breaker comes with complete support for international projects. We provide detailed technical documentation with each shipment. We support FOB trade terms for export orders. Professional wooden packaging protects the breaker during ocean transit. Our packaging meets international shipping standards. We understand that breakers play a critical role in grid safety.
