VPI1500 Fully Automated Vacuum Pressure Impregnation System | For Motor & Transformer Windings

The VPI1500 Fully Automated Vacuum Pressure Impregnation (VPI) System, manufactured by WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD., is a state-of-the-art industrial solution designed for the critical insulation treatment of high-voltage motors, explosion-proof motors, and transformers. This system significantly enhances the mechanical strength, insulation grade, moisture resistance, and anti-mold performance of electrical windings through a precisely controlled vacuum and pressure impregnation process. Engineered for reliability and efficiency, the VPI1500 automates the entire cycle—from vacuum drying and resin impregnation to pressurized curing—ensuring consistent, high-quality results for demanding electrical manufacturing applications.

Built to rigorous standards including GB150 and JB/T7674, the system features a robust Φ1500×2500mm vertical impregnation tank constructed from pressure vessel-grade materials (Q345-R, 16MnR). It integrates a complete workflow: a heated and agitated resin storage tank, a high-efficiency vacuum system with 2X-100 rotary vane pumps, a 12MPa hydraulic system for tank operation, and an intelligent PLC-based control system. Operators manage the process through a 21-inch touchscreen interface with full data logging, real-time curve display, and recipe management, ensuring process repeatability and traceability. This fully automated VPI equipment is the ideal choice for manufacturers aiming to improve product reliability, extend service life, and streamline production.
