    AI Overview
    Hi-Efficient Conveniently Vacuum Used Transformer Oil ...
    A vacuum insulating oil purifier is a specialized machine designed to remove water, dissolved gases, and solid impurities from insulating oils (transformer oil) using vacuum dehydration and mechanical filtration. It restores dielectric strength (typically to
    >75kVis greater than 75 k cap V
    >75𝑘𝑉
    ) and purity to transformer oil for equipment like transformers, circuit breakers, and capacitors, extending their lifespan. 
    Key Functions & Capabilities 
    • Moisture Removal: Removes free, emulsified, and dissolved water from oil, bringing water content down below
      33
      3
       ppm.
    • Degassing: Eliminates dissolved gases (such as hydrogen, methane, acetylene) to reduce oxidation and prevent gas faults.
    • Particle Filtration: Removes solid contaminants using multi-stage filters (e.g.,
      0.50.5
      0.5
       to
      11
      1
       micrometer precision) to keep oil clean.
    • Vacuum Function: Some units can perform vacuum drying and oil injection on electrical equipment, allowing energized, on-site maintenance (online) or offline purification. 
    Common Types and Features 
    • Single Stage (ZY/ZYA): Effective for general maintenance, offering quick removal of water and impurities.
    • Double Stage (ZYD/ZYD-II): Features high-vacuum, roots pump systems suitable for 110kV and above, delivering higher dielectric strength improvements.
    • Components: Typically include heaters, vacuum chambers, filters, and automated controls for temperature, flow, and safety. 
    Industries Served 
    • Power transmission and distribution
    • Power plants and substations
    • Manufacturing enterprises for electrical equipment 
    Models range in capacity from small portable units (
    7070
    70
     gph) to large industrial systems (
    4
    ,
    000
     gph or more), ensuring suitability for varying site needs.
