Based on ZYD-I, Series ZYD-I-W Enclosed Weather Proof Type Double Stage High Vacuum Transformer Oil Regeneration Purifier is equipped with Weather Proof Enclosure, very suitable for outdoor use. ZYD-I-W is mainly used for purifying the insulating oil in all kinds of large power equipments that are above 110KV especially for the area, where altitude is over 500 meters.
1.High vacuum: High point-Vacuum≤5pa Working-vacuum≤35pa
2.High absorption speed: Absorption speed power≥333L/Sr.
3.Duplex 3D stereo-evaporation, eliminating the liquid water quickly
4.UK G technology by which the trace water that is show chain, such as dissolved water, can be removed effectively.
5.Distinctive removing impurities system filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power
6.Effectively remove the oxidation, free carbon ect.
7.Especially applied to vacuum oiling and drying for power transmission equipments that are over 110KV
8.Can be operated both on-load and off-load.
Comparing with the single-stage vacuum oil purifier, this machine dewaters, Degases and removes the impurities more quickly, more completely. It not only improves the oils breakdown voltage value much higher but also can recover the oil anti-oxidation, Acidity and so on. As the bridge-type vacuum linking system, it is used for filtrating system as well as an independent vacuum power supply to vacuum oiling of power equipment.
