The VPI-1500 Semi-Automatic Vacuum Pressure Impregnation System, engineered by WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD., is a cost-effective and reliable solution for the insulation treatment of electrical windings in high-voltage motors, explosion-proof motors, and transformers. This system significantly improves the mechanical strength, electrical insulation, moisture resistance, and anti-mold properties of coils through a controlled process of vacuum drying and pressure impregnation. Designed for operations that prioritize robust performance and straightforward control, the VPI-1500 offers a balanced approach between automation and manual operation, making it an excellent choice for workshops and production facilities with skilled operators.

Built to stringent pressure vessel standards including GB150, the system centers around a durable Φ1500×2500mm vertical impregnation tank constructed from Q345-R and 16MnR materials. It integrates key subsystems: a heated and stirred resin storage tank, an efficient vacuum system powered by 2X-100 rotary vane pumps, a 12MPa hydraulic system for tank cover operation, and a reliable manual push-button control system. The process—evacuation, resin fill, pressurization, and drain—is managed through a centralized control cabinet, ensuring a repeatable and high-quality impregnation cycle. This semi-automatic VPI equipment provides a dependable, maintainable, and efficient method to enhance the longevity and reliability of critical electrical components.
