In today’s competitive world the electrical insulation materials and the processes are viewed with tremendous QUALITY and COST consciousness as the performance and life of the electrical machines are affected by the quality of the varnishing. The varnishing quality mainly depends on following: Insulating & mechanical properties of varnish. Proper filling of gaps & voids.

Systems are in flow rates from 300 LPH to 12000 LPH. Custom built plants can be provided as per customer’s specific requirement, such as more flow-rates. These plants work on low temperature, high vacuum principle. Plants mainly consist of heating, filtration and vacuum system. Heating system aids to the filtration and moisture removal. Filtration systems remove suspended particles down to 1 micron such as rust, dirt, scales, colloidal carbon etc. Vacuum Systems remove moisture (emulsified as well as dissolved) down to < 5 – 10 ppm depending on the working vacuum of the plant.

Vacuum Impregnation Plants and Pressure Impregnation Plants is designed for varnish impregnation to be carried out in following steps and will be generally as per the schematic diagram attached.Pre-heating the jobs in either Impregnation Chamber or in Oven if you have a less time available. Evacuation of Impregnation Chamber (after putting the jobs) to make the voids in the jobs clear and drying of jobs for specific time & required temperature vacuum.

High-Vacuum Transformer Oil Filtration And Dehydration Plants are suitable for all types of electrical insulating oils. We have standard high-vacuum filtration and dehydration plants to remove moisture (free as well as dissolved), gases, dirt and oxidation products from mineral-based and synthetic, silicon oils and others.

Evacuation of Impregnation Chamber (after putting the jobs) to make the voids in the jobs clear and drying of jobs for specific time & required temperature vacuum. Induction of impregnant (Varnish) in the Impregnation Chamber from impregnant Tank to submerge the jobs in it. Pressurize the Impregnation Chamber with dry air or nitrogen to fill the voids with Impregnant. Return the varnish to Impregnant Tank. Cure the jobs either in Impregnation Chamber or in Oven for specific time if time available is less
