In the manufacturing of electric motors, transformers, generators, and other electrical equipment, insulation treatment is a critical factor determining product lifespan and reliability. Vacuum Pressure Impregnation (VPI) technology has become the industry-standard process for manufacturers pursuing advanced quality and performance.
As a globally recognized leader in electrical insulation solutions, VPI vacuum pressure impregnation systems are redefining high-end manufacturing standards thanks to their exceptional penetration capability, efficiency, and process consistency.
How Does VPI Enhance Product Performance?
Deep Penetration: High vacuum removes air from within windings, followed by positive pressure to force resin into every micro-void—achieving 100% void-free insulation.
Extended Service Life: Effectively blocks moisture, dust, and chemical corrosion, significantly enhancing motor durability under harsh operating conditions.
Eco-Friendly & Energy Efficient: Closed-loop system design minimizes resin waste, aligning with green manufacturing principles.
