General description :

  

 

JDW-0.5/400 type, JDW-0.5/500, JDW-0.5/600 type, JDW-0.5/800-type isolation switch for 500V50Hz outdoor power distribution lines, as a low-voltage side of transformer short-circuit protection and overload protection, to a certain conditions can meet the no-load transformers, load lines and rated operating current.

 

The basic conditions of use isolation switch:

  

 

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

 

The main technology parameter:
