Double Vacuum Transformer/ Insulating oil purifier

Double Vacuum Transformer/ Insulating oil purifier: 1adopts advanced double stage vacuum system 2equips high precision filters

ZYD model transformer oil purifier is double stages vacuum oil purification system, comparing single stage vacuum oil purifier, besides vacuum pump, ZYD machine installs roots pump vacuum system which speed up evacuation much faster. The double stage vacuum transformer oil purifier adopts advanced two horizontal vacuum chambers which has large area three-dimensional flash distillation technique and remove water, gas, solids much quickly and completely. After purification by ZYD transformer oil purifier, the oil breakdown voltage can reach up to 75KV.

Application

Series ZYD Double-stage transformer oil purifier can quickly remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil’s dielectric strength, effectively making sure electric equipments working safely and normally. Series ZYD oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than 110V substation live line work onsite. Meanwhile, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.

Advantages

Comparing with single stage transformer oil purifier, Series ZYD oil purifier can increase the effectiveness more than three times, more quickly and completely dewater, degas, remove particles to get higher dielectric strength. This equipment can be used as independent vacuum source with the functions of vacuum drying and vacuum oiling for the electric plants.
