The load switch is a simple switchgear with SF6 gas for insulation and arc extinguishing. It handles load and overload currents, as well as no-load operations for lines, transformers, and capacitor banks. Three-position load switches, which can be on, off, or grounded, are straightforward and cost-effective. They offer long life and strong breaking force, with the added benefit of easy three-position operation and the ability to break small currents under harsh environmental conditions. These switches are ideal for medium voltage distribution networks in urban and rural areas. The SF6 load switch combined with a fuse is designed to handle overload currents within the switch's rated capacity and normal operating currents, as well as the "transfer current" breaking. The high-voltage side short-circuit and overload protection is provided by a high-voltage current-limiting fuse. When any of the triggers are activated, a linkage mechanism automatically opens all three phases of the load switch simultaneously. This combination meets the operational and protective needs of various distribution systems under normal and faulty conditions.

FLN36-24kV load breaker switch uses SF6 gas as arc extinguishing and insulating medium. The switch has three operating stations: open, closed and grounded. It is known for its compact size, convenient installation and excellent environmental adaptability.

FLN36-24 load switch and FLRN36-24D load switch plus fuse combination device are suitable for the protection and control of electrical equipment in power supply and transformer stations, especially for ring network units, cable branch boxes and distribution switch stations.
