General description :

 

WTR 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:

1. Altitude:≤2000m
2. Ambient air temp.:upper limited +40^oC,lower limited -25^oC
3. Eathquake intensity ≤8°
4. The ground have not fire,exposion danger,seriously nasty,chemical etch and serious shake

 

The main technology parameter:
