VACUUM PRESSURE IMPREGNATION PROCESS (VPI)
Our 7’ diameter Vacuum Pressure Impregnation (VPI) system has the ability to process up to 5000 HP Motors. It is a system in which vacuum and pressure are used to assist the penetration of liquids into various materials and devices. It is often used to impregnate electrical apparatuses with insulating resins (electrical varnishes), because it can provide a virtually void free insulation with only one VPI cycle. VPI produces top quality insulation systems, better mechanical strength, environmental protection, and superior chemical, moisture, and corona resistance.
Tram utilizes John C. Dolph’s CC1118LV one part, low viscosity, thixotropic (materials that liquefy or flow when agitated and return to a thick gel like consistency when allowed to rest), impregnating epoxy compound. This compound is unique for use where higher voltage, low corona, chemical resistance, and electrical insulation properties at elevated temperatures are required. Motors processed with one cycle in CC1118LV have passed Navy total submersion testing per MIL-M-17060E. After this process, the electrical apparatus is placed in the bake oven to cure at 302 degrees Fahrenheit.
