ZJ vacuum creation machine

transformer drying or oil-injecting by vacuum

 

This ZJ vacuum creation machine 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:

GIS connection available

Digital vacuum degree management

Anti-absorption

Machine can start fast

Strong vacuum pumping capacity

Stable performance

Easy operation

 

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.
