Kurz gefasst
Vacuum Pressure Impregnation (VPI)
28 january 2026
Electro Adda manufacturing process includes Vacuum Pressure Impregnation (VPI) for medium to large machines or whenever dictated by the application/client/specification e.g. inverter duty.
Our system is automatically controlled – dry out of stator before VPI, resin temperature, cycle timing, pressure and vacuum parameters – to guarantee the optimal resin performance and deep penetration.
Further to VPI, the stator will be cured to uniformly distribute the resin on the volumes.
Cycles are automatically recorded to keep traceability.
To confirm the process matches the design and contractual parameter – Partial Discharge readings per IEC60034-18-41 are conducted to move the part to the next steps.
All in house, all made in Italy!
