Introduce (insert product title here)

It is widely used in the oil purification treatment and vacuum hot oil circulation drying in the installation and maintenance of various large transformer equipment.. Not only use in Insulating oil purification treatment in 110KV-550KV transformer, but also applies to high-grade new oil, the high depth of processing imported oil. Compared with the single-stage vacuum purifier machine, the machine increases the Roots pump pressurization system, secondary high vacuum separation systems and three-dimensional flash rapid evaporation system , it can quickly dewater, degas, and remove the acetylene, acid value and free carbon , The transformer oil breakdown voltage value will be higher after treated, It ‘s not only used for oil purifier but also as a separate vacuum source which have the function of vacuum drying and oil injection for transformer equipment.

4.6. Advantages and characteristics

double stage Insulation oil vacuum purifier machine process design, double stage efficient vacuum system, kaiqian unique Vacuum separation technique, it can quickly dewater, degas, and remove the acetylene, acid value and free carbon, colloid. increase oil limit Breakdown voltage value.

(a) Oil initial value: water content: ≤50mg / L, containing gas: ≤10% (volume fraction), the breakdown voltage: ≥25KV

(b) Secondary purification: water content:≤15mg / L, containing gas:≤0.1% (by volume), the breakdown voltage: ≥50KV (ball electrode).

(c) Three purification: residual moisture: ≤5-10ppm, residual gas≤0.05%, acetylene content :0, the breakdown voltage:≥60KV (ball electrode)

Note: water content and gas content measurements in accordance with relevant GB, DL or IEC standards.
