FLN-24kV SF6 load break switch is a switch equipment for medium voltage switchgear, using SF6 gas as arc extinguishing and insulating medium.There are three working positions:open, closed, earth position in the switch. The compact size, easy installation, and fine adaptability to environment make the switch suitable for many different applications.
It can be divided into two types: FLN -24kV ( K type single spring operating mechanism ),FLRN -24kV(A type double spring operating mechanism). The latter type could be equipped with fuse combination, having control and protecting function, which can be used for power supply and substation as a protecting and control device, especially suitable for ring main unit, cable distribution box and switching substation.
