Frequently Asked Questions (FAQ)

Q1: What type of resin can be used with the High Vacuum Impregnating Equipment?
A1: The system is compatible with most insulating resins, including epoxy, polyester, and special varnishes. Resin heating and cooling functions ensure stable viscosity control.

Q2: How does vacuum pressure impregnation improve motor insulation?
A2: By combining deep vacuum with controlled pressurization, the resin penetrates fully into coil windings, eliminating air bubbles and voids. This results in stronger insulation, higher dielectric strength, and better resistance to moisture.

Q3: Can this equipment handle large transformer windings?
A3: Yes. With a large-capacity impregnating tank and high vacuum system, it is designed to treat both small and large-scale motor and transformer windings efficiently.

Q4: What safety features are included?
A4: Over-pressure protection, hydraulic anti-fall design, explosion-proof lighting, PLC alarms, and interlock systems ensure maximum safety during operation.

Q5: Does your company provide installation and training?
A5: Yes. We supply full installation, on-site commissioning, operator training, and technical support to ensure smooth start-up.
