After long time using,the insulation oil would contains large number of particles,in order to restore the oil quality,users must purify the used insulation oil.Purification can be one of the following methods:(1) Filtration: can remove fiber,black carbon, metal, sludge and other solids(2) Heating: 

 Nowadays, CENTRIFUGE, COALESCER and VACUUM DEHYDRATION are the 3 ways that mostly employed to remove water contaminants from oil. For removing water contaminants, the disadvantage of a centrifuge is that it can only deals with Free Water (>200ppm), and has little to do with Emulsified and Dissolved

Insulating fluids, known for its dielectric features and chemical stability, are commonly used in power and distribution transformers. The main function is to insulate, prevent electric arc taking place and dissipate the heat generated during the transformer’s working. However, the oil in service wi

Can lubricating oil be recycled—and how?Yes, oil can be recycled. Engineers Joseph Franceschi and James Condela of Universal Lubricants told that. In general, you take crude oil and refine it to make a lubricant. This is called base lube stock. Then you have to take that base lube stock and blend it

Transformer oil acts as a medium for insulation and transmission of heat,it requires choosing the right viscosity to ensure that oil played an ideal cooling effect in the long-time running, choice of appropriate low-temperature viscosity to ensure safe working of transformer stopped running when sta

(1) Often note oil level. 　　(2) The pump start and slowly open the valve again. 　　(3) Often note whether the pump operation correctly, there is no special sound, the motor is running. 　　(4) Attention to the cooling water is interrupted.(5) Note pump temperature not exceeding 40 ° c(6) If after parki
