Vacuum dehydration oil purification system
October 28, 2025
The vacuum dehydration oil purification system serves as the most effective method for removing the water and gases that contaminate transformer oil, ensuring stable electrical performance and long-term equipment reliability. Moisture affects both the insulating oil and the cellulose-based solid insulation, reducing their dielectric properties and accelerating the aging process. In new transformers, the moisture content in solid insulation is typically below 1 %. However, during normal operation, it gradually...

Transformer Oil Degassing Plant
October 28, 2025
The main principle of transformer oil degassing involves removing dissolved gases and air from the insulating oil in electrical equipment. The goal of transformer oil degassing is to improve the dielectric strength of the oil and prevent transformer breakdowns caused by the presence of gases and moisture. During operation, transformer oil gradually absorbs air, water vapor, and decomposition gases. If not removed, these impurities reduce insulation resistance and accelerate oil...

Transformer Oil Dehydration Unit
October 28, 2025
The transformer oil dehydration unit is designed to address one of the most complex challenges in electrical engineering — the presence of water in transformer oil in multiple associated forms. Modern research shows that in oil-filled electrical equipment, water can exist in four main states: molecularly dissolved, bound, emulsified, and surface (layered). These states are not static — they continuously transform into one another, depending on temperature, electrical field intensity,...

Transformer Oil Degassing Plant
October 23, 2025
Transformer oil degassing is a process required for high-voltage electrical equipment. During the service life of transformers, the insulation system undergoes various physicochemical changes that lead to the formation of decomposition products — solid, liquid, and gaseous substances. These changes are intensified when the insulation becomes moist. Both solid insulation materials based on cellulose (such as paper and cardboard) and transformer oil release gases during gradual aging. Among these gases...
