Brief Introduction:ZYD double stage transformer oil filtration machines are
designed for use in treating electrical insulating oil in the oil-filled
electrical equipment. As the oil purifying nanotechnology, this machine can
treat oil more quickly and more completely, remove the soluble and insoluble
polar contaminants and makes the oil limiting voltage-withstand value much
higher than the ordinary vacuum oil purifier.
It also 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
Scope of our Supply:
All types with different
functions, with various spare parts can be supplied according to Customer’s
In a single pass through
the purifier at a full flow rate:
Water Removal: From 50 ppm down to less than 5 ppm in a single pass & down to 3
ppm after two passes. (According to the PPM Tester)
Gas Removal: From fully saturated with air (10% to 12% by volume) down to less
than 0.1% by volume.
Particulate Matter Removal: 98% of particles over 0.5mm or over 1 mm or over 5mm at customers
Dielectric Strength: Improve
dielectric strength up to 75-80KV for New oil.
a. Degassing, dehydration and filtering impurities of transformer
b. Remove acidity, sludge, free carbon, other soluble oil decay products and
c. It can vacuum filling oil to transformer, vacuum dry transformer and on-line
operation transformer .
d. It is mainly used for purifying the insulating oil, transformer
oil, mutual oil, switch oil, dielectric oil and so on. The standard ZYD system
is designed for processing oils in workshops, in storage tanks or directly in
transformers (energized or de-energized transformers).
