    Pre-drying Treatment
    - Low Loss, Low Local Discharges, Low Noise, Strong Heat Radiation, Capable of Running under 150% Nominal Load with the aid of Forced Air Cooling.

     

    OUR ADVANTAGE:

    1. Long service life

    Our transformers have a long service life of 30 years. The conservator tanks of our transformers are fully sealed, bolted or welded to the edge without any clearance, so the oil in the transformers are insulated from air, prolonging the service life.

    2. Completely oil-filled and hermetically sealed

    It is completely oil-filled and hermetically sealed without a storage tank. The oil volume changes with temperature and load, totally adjusted by the elasticity of the conservator tank, reducing the size of transformers.

    3. Protecting the insulation paper and insulation cardboards from oxidation.
