Introduction:
 
It is mainly used for vacuum drying and vacuum oil-injecting for high voltage electrical transformer as 220KV, 500KV,±800KV, 1000KV. Strong vacuum pumps make working vacuum degree to 10 Pa and limit vacuum degree to 1 Pa.
 
 
Features: 
 
1) GIS connection available

2) Digital vacuum degree management

3) Anti-absorption

4) Machine can start fast

5) Strong vacuum pumping capacity

6) Stable performance

7) Easy operation

8) There is a combination of axial fan and condenser to deal moisture and gas from vacuum pump and roots pump, it can prolong time to change vacuum oil while meet emission standard.
