High Voltage Transformer Oil Purifier Insulation Oil Treatment
Plant
I. Description and Function of transformer insulation oil purifier
The High Voltage Transformer Oil Purifier Insulation Oil Treatment
Plant is used for the dehydration and degasification of electrical
insulating liquids including transformer oils.polybutene and
silicone fluids to increase and maintain their dielectric strength.
The processing includes the removal of free and soluble water,
dissolved air and gases and particulate matter.
The most important applications of Transformer Oil Degasification
Systems are in the field of extra high voltage transmission and in
the manufacture of electrical apparatus.
In addition, the high vacuum process is used in the degasification
of cable oils including polybutene. Outside of the electrical
industry, this process is used for electronic and radar equipment,
vacuum pump sealing oils, brake fluids and refrigeration oils –
including phosphate esters and silicones.

III. Insulation oil purifier machines' advantages
Comparing with the single stage vacuum oil purifier, this machine
can dewater, degas and removes the impurities more quickly, more
completely, and makes the oil BDV (Breakdown Voltage) of 75 KV or
higher. As the bridge-type vacuum linking system that can purify
and also can be an independent vacuum power supply, this machine
can treat the electric insulation devices.
IV. Working Principle
The insulating oil is conveyed into the degassing tank by means of
pressure difference. Oil is indirectly heated by the heater, thus
avoiding hot spots and over-swinging of the pre-selected operating
temperature. The special degassing system and geometry with several
stages in degassing tank creates a large oil surface and a
resulting thin film for most effective maximum degassing.

eliminate them effectively and efficiently.
LV series: Lubrication Oil Filter System are suitable especially for
purifying and restoring hydraulic oil, machine oil, coolant oil and
various other lubrication oil.
GER series: Used oil regeneration system is suitable to regenerate used
internal-combustion engine oil including diesel engine oil,
gasoline engine oil, and used hydraulic oil, other used lubrication
oil of machinery.
GED series: it is used to recycle all kinds of waste oil into base oil or
diesel oil with high quality.
