ZJ Series High Vacuum Pumping System
The ZJ series high vacuum pumping system is mainly used for vacuum drying and vacuum oil-injecting for high voltage electrical transformer as 220KV, 500KV, ±800KV, and 1000KV. Strong vacuum pumps make working vacuum degree to 10 Pa and limit vacuum degree to 1 Pa.
