New Design 35kV 40.5kV Indoor Three Work Positions SF6 Load Break Switch For Ring Main Unit Switchgear
FLN36 -40.5 SF6 load break switch use SF6 gas as arc extinguishing and insulating medium. There are three work stations:opening, closing and grounding in the switch. It has small volume, installing easy-to-use, strong environmental adaptability and other characteristics.
FLN36-40.5 load break switch and FLN -40.5D load break switch plus fuse combination, can be used to protect and control the electric equipments for power supply and transformer substations, which is especially suitable for ring net cabinet, cable branch cabinet and distribution switching substation.Normal ambient condition:
