    Dielectric Oil Treatment Plant With High Vacuum
    A dielectric oil purification plant is a specialized system that cleans insulating oil in transformers and other electrical equipment by removing water, gases, and solid contaminants, restoring its dielectric strength for safe operation, often using high-vacuum dehydration, degassing, and fine filtration to meet strict purity standards like ≤3-5 PPM water and ≥70kV breakdown voltage. These plants can be fixed or mobile, ranging from small units for substations to large systems for EHV transformers, and also perform vacuum drying and oil filling for equipment. 
    Key Functions & Processes 
    • Moisture Removal: Uses vacuum dehydration, molecular sieves, and atomization to extract free, emulsified, and dissolved water.
    • Gas Removal: High vacuum and specialized chambers remove dissolved gases (like acetylene, hydrogen) and air.
    • Particle Filtration: Multi-stage micro-filters remove solid particles, sludge, and carbon down to 1 micron.
    • Degassing & Drying: Creates a high vacuum to dry the oil and the equipment itself, crucial for new installations or maintenance.
    • Oil Regeneration (Optional): Can remove acidic byproducts and polar materials, extending oil life. 
    System Features 
    • High Vacuum: Systems often pull vacuums down to 0.05 mbar using double-stage pumps and blowers.
    • High Automation: Features automatic temperature, pressure, and flow control, plus safety interlocks.
    • Portability: Many are trailer-mounted for on-site mobile purification.
    • Application: Suitable for new/used oil, from smaller units to large systems for EHV (Extra-High Voltage) and UHV (Ultra-High Voltage) transformers. 
    Benefits 
    • Improved Safety: Prevents electrical breakdown and faults.
    • Extended Equipment Life: Maintains oil properties, prolonging transformer service life.
    • Cost Reduction: Reduces downtime and the need for frequent oil replacement.
