Application: It is mainly used for purifying the insulating oil in all kinds of large power equipments, which are above 110KV, especially for those areas over 500 meters. Advantages: Comparing with the single-stage vacuum oil purifier, this machine dewaters, degases and removes the impurities more quickly, more completely, and makes the oils' limiting voltage-withstand value much higher. 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. Features: 1 High vacuum: ultimate vacuum = 5Pa,working vacuum = 35Pa 2 High absorption speed: absorption speed power = 333L/s 3 Duplex 3D stereo-evaporation, eliminating the liquid water quickly 4 UK G technology by which the trace water, such as dissolved water, can be removed effectively 5 Distinctive remove impurities system filtering through double FH trapezoidal network and absorption by high polymer without mechanical power 6 Especially applied to vacuum oiling and drying for power transmission equipments which are over 110KV 7 It can be operated both on-load and off-load contact
