2,Low Voltage Isolate Switch
Key words : Switch,Isolate Switch,Low Voltage Isolate Switch,Fuse Switch Disconnector
Rated voltage:500VRated current:400A-1250A
General description :
GWR series of outdoor low-voltage fuse type isolating switch (hereinafter referred to as isolating switch), widely used in rural power transformer low voltage side outlet, branch feeders, are affixed to implement fuse replacement products. Under certain conditions, can be divided into a small load off, and Closing overhead lines and transformers. Isolation switch prevent low back supply, reduce power outage area, ensure the maintenance personnel safety, improve reliability and avoid high-altitude operations, more great significance
The basic conditions of use isolation switch:
Altitude:≤2000mAmbient air temp.:upper limited +40oC,lower limited -25oCEathquake intensity ≤8°The ground have not fire,exposion danger,seriously nasty,chemical etch and serious shake
The main technology parameter:
