FL(R)N36(12 40.5kV) Sulphur hexafluoride(SF6) high-voltage load switch is a switchgear with a rated voltage of 12-40.5kV, with SF6 gas as the arc-extinguishing and insulating medium, as well as the three work positions such as closing, breaking and grounding; it has the features such as compact, easy to install and use and highly adaptable to environments.
This series of load switch is divided into FL(R)N36(12-40.5kV) (K type single spring operating mechanism) and FL(R)N36(12-40.5kV) (K type single spring operating mechanism), which are of different sizes and with different operating modes.
This series of load switches are divided into FL(R)N36(12-40.5kV) (K type single-spring actuator) and FL(R)N36(12-40.5kV) (A type double-spring actuator). FL(R)N36(12-40.5kV) can compose load switch + fuse combined appliance pit with control and protection function for protection and control of electrical power equipment in power supply and substation, is specially ideal for ring main units, cable junction boxes and power distributors.
It meets these standards such as IEC60265, IEC62271, GB3804, GB16926, etc.
