Product Description

Application
SF6 circuit breakers are widely used in high-voltage power systems due to their excellent arc-quenching performance and compact design. Key applications include:
1.High-voltage transmission networks (72.5 kV-800 kV) for fault interruption and gridprotection.
2.Gas-insulated switchgear (GlS) in urban substations, where space efficiency and pollutionresistance are critical.
3.Renewable energy plants (wind/solar farms) to manage frequent switching and faultcurrents.
4.Industrial power systems for protecting large motors, transformers, and distributionnetworks.
5.Railway electrification, ensuring safe interruption of 25 kV AC traction power.

Keystone
SF6 circuit breakers are indispensable in modern power systems because of their:
1.Superior arc extinction: SF6 gas rapidly absorbs free electrons, quenching arcs 100x fasterthan air.
2.High dielectric strength: Allows for compact designs, reducing substation footprint.
3.Low maintenance: Sealed construction ensures long service life (20+ years) with minimalupkeep.
4.Environmental adaptability: Operates reliably in polluted, humid, or extreme climates.
5.Flexible configurations: Available in dead-tank, live-tank, and GlS-compatible designs.

Usual Service Conditions
SF6 circuit breakers are designed to operate under the following standard conditions:
1.Ambient temperature: -30°c to +40°C (special designs available for extreme climates).
2.Altitude: Up to 1000 m above sea level (derating may apply for higher elevations).
3.Humidity: s95% relative humidity (non-condensing).
4.Installation: Suitable for indoor (Gls) or outdoor installations.Mechanical endurance: 2,000-10,000 operating cycles, depending on design.Electrical endurance: Capable of interrupting rated short-circuit currents (up to 63 kA ormore).
