Product Profile of High Vacuum Insulating Oil Processing Plants

High Vacuum Insulating Oil Processing Plants are manufactured by Nach Engineering Pvt. Ltd. Nach Engineering Pvt. Ltd. Is the manufacturer of Vacuum Machinery & Allied Products. The company develops, manufactures and supplies different types of equipments based on latest technological aspects which include plants for maintenance of power transformer in service, high vacuum insulating oil processing plants, vacuum/pressure impregnating plants of large capacities, etc.

High Vacuum Insulating Oil Processing Plants are manufactured with the purpose of commissioning & maintenance of all types of transformers. This plant comes with optional features of transformer evacuation system as per requirement; ionic reaction column for acidity correction and facility of additional inhibitors; and instrumentation for indication and recording various oil parameters.

Application of High Vacuum Insulating Oil Processing Plants are:
Requirement of working vacuum becomes much higher for treating oil having high acidity & low interfacial tension as compared to theoretical requirements of new oil. To meet this field conditions, high vacuum processing plants with multi stage designed are most effective.

For dehydration of these transformers multi stage plants can effectively meet :

• Oil in transformer which is in use, has high acidity and low IFT as compared to new oil, as per IS - 335.

• To enable moisture in paper insulation to migrate in the surrounding oil, it has to be maintained at higher temperature of 70°C to 80°C and also to a low dissolved moisture contained level. Single stage plants can achieve results as good as multi stage plants for treating new oils. But it takes longer time for oil in use. Thus improvements in transformer IR values will be slow and limited.
