General NSH VFD series is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. from the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system. VFD series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil. Operating conditions: The installation shall be designed to opeartae satifactory at ambient temperatures ranging from -20 deg.C to 55 deg. C Description NSH VFD series utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly. Edges To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly. Enhance the value of breakdown voltage greatly. Easy handling and maintenance. Inject oil into the transformers Online work Lower maintenance and replacement expenses High efficiency and effectiveness Small size, light weight, low noise Various sizes and configurations (shield) available.
