Latest company news about How Does Vacuum Pressure Impregnation (VPI) Equipment Empower High-End Manufacturing?

Amid the global energy transition and electrification wave, core components such as motors, electronic controls, and transformers are evolving towards higher power, smaller size, and longer lifespan. This presents unprecedented challenges for insulation processes—leading more and more industry leaders to choose Vacuum Pressure Impregnation (VPI) equipment as the key to a breakthrough.

Industry Demands Drive VPI Advancements

  • Wind Power Industry: Large direct-drive generators must operate for over 20 years in damp, high-salt-spray environments. Traditional impregnation can create micro-voids, leading to premature insulation failure. The VPI process achieves 100% void-free filling, significantly enhancing the reliability of offshore wind turbines.

  • New Energy Vehicles: Electric drive systems feature compact spaces, high temperature rise, and strong vibration. Hairpin motors treated with VPI not only boast more reliable insulation but also reduce partial discharge, meeting automotive-grade 8,000+ hour endurance tests.

  • Rail Transit: High-speed rail traction motors demand "zero failure." VPI transforms windings into a rigid monolithic structure, effectively resisting the mechanical stress from frequent starts and stops, ensuring operational safety.

  • Industrial Motors: Facing IE4/IE5 ultra-high efficiency standards, VPI helps customers easily comply and gain international market access by reducing temperature rise and copper losses.
