Double Stages High Vacuum Transformer Oil Purification Machine

Ⅰ. Here is a professional introduction of Double Stages Transformer Oil Purification Machine

The Double Stages High Vacuum Transformer Oil Purification Machine is a high-performance system designed to remove moisture, dissolved gases, and solid impurities from transformer insulating oil. With its two-stage high-vacuum system, it achieves deeper dehydration and degassing than single-stage units, making it ideal for high-voltage, large-capacity transformers and critical power equipment. It significantly improves dielectric strength (BDV) and helps extend the service life of transformers.  

In order to lower the amount of moisture, gasses dissolved as much as possible, and also in order to eliminate solid products of oil oxidation process, the highly accepted concept of power transformers maintenance assume that activities of periodical purification of insulating oil are performed in the electric energy. For this purpose, We developed the Double Stage High Vacuum Transformer Oil Purification System (Oil Purifier Machine) to reduce moisture, gasses content and remove particles, sludge for improving dielectric strength and maintain the characteristics of insulating oil. Through timely and proper purification of insulating oil, which can improve the properties of the entire isolation system, maintain the normal functioning, good work security and extend the lifecycle of power transformers.
