ZJA Double-Stage Cable Oil Cleaning Equipment Manufacturer, Vacuum
Insulation Oil Purifier/Transformer Oil Dehydration Machine
We can offer two kinds of machine for treating the waste
transformer oil,insulation oil and dielectric oil, which is ZJB
Single-stage vacuum oil purifer machine and ZJA Double-stage
transformer oil purifier machine.
This high vacuum oil purifier performs the function of upgrading
and reconditioning of insulating transformer oil by means of
removing impurities such as dust,gas,sludge,water etc. The major operation is heating, filtering, degassing and
dehydration. After recycling, it can boost performance of
transformers, circuit breakers, mutual inductors, cable and
capacitors which have insulation system. This machine specialize in
purifying transformer oil, insulating oil of high voltage and super
high voltage transformer. Additionally, it is also suitable for
treating low viscosity lubrication oil.
1.To remove free, soluble water, carbon, free and dissolved gases
and particulate matters, dust from insulating oil effectively and
2.With Vacuum pump and Roots pump.
3.Enhance the value of breakdown voltage greatly.
4.Easy handling and maintenance.
5.Inject oil into the transformers.
6.Lower maintenance and replacement expenses.
7.Automatic reverse-washing system will extend the lifetime of
filters and improve the performance of the filters.
8.High performance security system including pressure protection
device and automatic temperature controller makes purifier operate
9.Utilizes coacervation technology, coalescing technology,
separating technology and refined purification technology. To
remove free, soluble water, carbon, free and dissolved gases and
particulate matters from insulating oil effectively and rapidly.
Dehydration (Degas) System
1, The vacuum chamber has flash tower, which can evaporate the
water efficiently. Also it has the spraying nozzle with degassing
elements design. The heater, being placed on the vacuum vessel,
becomes an evaporator. Thus the flash tower of vacuum vessel is
three times more than that of the general vacuum vessel. This
innovation can dehydrate and degas effectively and efficiently.
2, The optimal structure of the dehydration (degas) system enlarges
the surface area of oil exposed to the vacuum system and extends
the flowing distance of the oil in the vacuum system. Thus there
has sufficient time to remove the moisture and gas from the oil by
Filtering System (particulate matter removal)
1, The filtering materials with variable apertures are made of
specialized glass fiber. The sizes of the filtering fiber and
aperture dwindle gradually in the different filtering stages. The
impurities with different particulate sizes are filtered step by
step. The capability of removing particulate matters and impurities
is improved greatly by this method.
2, The filtering system has stable and prefect filtering fineness.
The filtering fineness has several grades, including 1, 2, 3, 5, 6,
10 Micron etc. Oil β>=1000 after filter.
3, The filtering system is equipped with reverse rinse and filth
device. It improves the effectiveness of filtering and extends the
lifetime of filter awfully.
Oil heating System
1, The unique heater structure heats the oil uniformly.
2, Oil Heater System assures less then 1.0 w/cm2. During the
heating process, the deterioration of the oil caused by overheating
3, The oil temperature can be adjusted between 20C to 80C. The
heater is controlled manually or automatically. The heater will
stop automatically when the oil temperature reaches a certain
4, Being installed with safety protection devices, the heating
system is secure and reliable. The heater will stop operation
automatically when the oil volume of inlet is too low to avoid the
damages of the heater.
Electrical Apparatus Controlling System
1, The main components of the electrical apparatus made by
Schneider, Siemens and so on ensure the safety of the controlling
2, Having several protection systems which will avoid oil ejection,
overload and over voltage etc.
Oil-level Controlling System
1, The oil-level floating ball or infrared liquid level automatic
controller system are installed in the vacuum vessel to control the
oil level so as to avoid the oil being suctioned into vacuum pump
in the operation.
2, The new innovation of eliminating froth can avoid the oil being
suctioned into vacuum pump.

Different between ZJA & ZJB
Double stage with a ROOTS PUMP and vacuum pump
Single stage only with vacuum pump
of the oil after treatment
Water content of the oil
The Difference of Single Stage ZJB and Double-stage ZJA are
1. ZJA is more applied to process ultra-high transformer oil,
especially used to large power transmission and transformation
equipment more than 110KV, but ZJB mainly treat the oil less than
2. The speed of ZJA is faster than ZJB
3. ZJA can remove Acetylene and Firedamp more thoroughly and
4. The index of oil breakdown voltage is different, ZJA is more
than 75KV, but ZJB only 60-65KV.
