A practical evidence checklist for RFQ preparation and supplier evaluation.
Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official VPI product page describes vacuum pressure impregnation insulation for high-voltage motor stators and rotors, transformers and reactors, suitable for class H resin, with impregnation tank, varnish storage tank, vacuum pump, hydraulics and varnish return and degassing, automatic process data recording and multiple interlocks; the About page on the same domain states it was founded in 2009 and makes transformer production equipment, with a factory in Pizhou, Jiangsu producing over 200 machines a year. Tank size and vacuum and pressure parameters must be confirmed in the proposal.

Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
According to directory data, the main impregnation chamber volume typically ranges from 500 to 2000 liters. However, this is a reference range; actual capacity depends on the specific model and configuration. Always confirm with the manufacturer.
The minimum achievable vacuum pressure in the chamber is typically between 0.1 and 1 mbar. This level is necessary to effectively remove air and moisture from porous substrates. Verify the exact capability for your chosen model.
The system is compatible with common resins such as epoxy, silicone, and polyester. The choice of resin depends on the application requirements. Always check compatibility with the manufacturer.
The system requires a three-phase electrical supply of 380 V AC ±10%, 50/60 Hz, as per IEC 60038. Ensure your facility meets these requirements. Confirm with the supplier for specific models.
