An internationally renowned high-voltage motor manufacturer, seeking capacity expansion and process upgrades, planned to procure a large-scale VPI vacuum pressure impregnation system for insulating its high-voltage motor stator and rotor windings. The client imposed stringent requirements regarding vacuum level, pressure uniformity, impregnation efficiency, and automation control, while mandating full compliance with international safety and environmental standards.
Following multiple rounds of technical discussions and on-site inspections, the client ultimately selected our company and signed a contract for the VPI turnkey system. The project scope included the VPI impregnation tank, varnish storage tank, vacuum system, pressure system, heating and temperature control system, fully automatic PLC control system, and associated piping and valves.
The successful delivery and acceptance of this VPI equipment further validates our profound technical expertise and project management capabilities in the field of vacuum impregnation. Since commissioning, the client has achieved a first-pass impregnation qualification rate of 99.6% for high-voltage motor products and reduced the single-batch impregnation cycle by 18%, significantly lowering energy consumption and resin usage, thereby generating tangible economic benefits.
