ZJA Series Used Transformer Oil Filtration Machine for 110-500KV Project

ZJA Series Used Transformer Oil Filtration Machine for 110-500KV Project

Transformer oil maintenance is the key to transformer reliability, performance and longevity. Your transformer`s insulating oil should be free from moisture, dissolved gases and particles that accumulate as the oil ages. Even some new oils may require treatment to limit these contents to acceptable levels.

ZJA Series Used Transformer Oil Filtration Machine is designed to remove contaminants (particulate, water, gasses, acids, etc.). We are a design, engineering and manufacturing company capable of application customization for best solutions.

» Water Removal: Overall Water Content ≤5 PPM by removing free, emulsified, and dissolved water.

» Particulate Removal: Particle counts as low as 1 micron.

» Entrained Air and Gas Removal ≤ 0.3%

» Acid Removal: can be equipped with fullers earth towers to neutralize acid and Lower TAN to < 0.03 KOH/g

» Dielectric Strength: ≥70 kV per ASTM 877

1. Two separating house made by stainless steel. Oil flow by rotation in stereo evaporation to degas and dehydrate well. (Patent no. ZL200420061085.6).
2. The combination of axial fan and condenser make vapor from vacuum pump and roots pump into water, it can prolong time to change vacuum oil while meet emission standard.
3. Multiple Filter Housings With Cartridge Style Filter Elements, big filtering area to hold more particles.
4. Control system: IEC standard with each wire marked. tri-unity control to avoid wrong operation as lack-phase, wrong phase and overload.
5. Oil level in vacuum tank is controlled by photoelectric switch, which is flexible and accurate. No oil-spraying. (Patent no.: ZL200420060973.6).
