Transformer & Motor VPI Equipment (Vacuum Pressure Impregnation Plant)This VPI (Vacuum Pressure Impregnation) Equipment is engineered to enhance the moisture resistance, heat resistance, insulation, and mechanical properties of transformer and motor coil windings. By impregnating and filling gaps under vacuum and pressure, it forms a tough, elastic, and dense varnish film. Featuring a 0.6 MPa working pressure, ≤50 Pa ultimate vacuum, and compatibility with Dupont NOMEX paper & German MORA tech, it ensures uniform coating, firm adhesion, and superior insulation for high-efficiency production.

Description
1. Core Features & Advantages ① Superior Insulation & Mechanical Protection VPI technology penetrates the internal gaps of coils under vacuum, then presses varnish into the insulation. Compared to general coating, it creates a uniform, dense film with firm adhesion, significantly improving moisture/heat resistance and mechanical strength. ② Optimized for NOMEX & Advanced Tech Ideal for transformer/motor impregnation using Dupont NOMEX paper insulation. Meets production needs of German MORA motor technology, ensuring high-quality dipping processes. ③ Precision Vacuum & Pressure Control Impregnating tank features ≤50 Pa ultimate vacuum (working: 300–1000 Pa) and 0.6 MPa working pressure (design: 0.675 MPa). Leakage rate ≤133 Pa·L/s ensures stable processing conditions. ④ Customizable & Automated System Combining years of VPI design experience, the system includes hydraulic door opening, returning paint, cooling, and PLC measurement/control. Pressure/pneumatic system can be prepared by buyer; full technical proposal provided for custom needs. ⑤ Key Process Impact VPI is a critical step directly affecting production quality and efficiency. This equipment guarantees thorough impregnation, minimal deformation, and long-term reliability of active parts. 2. Key Technical Parameters
