33kV SF6 Load Break Switch
FLN36 -40.5 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 a 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 equipment for power supply and transformer substations, which is especially suitable for ring net cabinet, cable branch cabinet, and distribution switching substation.
Normal ambient condition:
1. Altitude: ≤2000M
2. Ambient temperature: -40℃-+40℃
3.Relative humidity: daily average ≤95%, monthly average ≤90%.
4.Earthquake intensity: ≤8 degree
Products with special requirements, specifications, and dimensions that need to be improved can be designed and manufactured according to user requirements.
