Assembly & Quality Control
| Process / Test Item | Technical Method & Data | Quality Result & Impact |
|---|---|---|
| Insulation Screening | 5,000V Megger test applied to all windings before packing. | Confirm high dielectric stability and prevents short circuits. |
| Induced Overvoltage Test | Applied 2x rated voltage at increased frequency per IEC standard. | Verifies inter-turn insulation integrity against transient grid overvoltages. |
| Thermal Monitoring | PT100 sensors verify full-load temperature stays below Class H limits. | Prevents overheating, resulting in stable continuous operation. |
| Partial Discharge Test | Measurement conducted at 1.3x rated voltage; discharge level ≤10 pC. | Prevents localized insulation breakdown, ensuring zero early failures. |
| Torque Verification | All busbar connections tightened via calibrated digital torque wrenches. | Eliminates loose contacts to prevent hot spots and terminal damage. |
FAQ
Q: Can this equipment operate in high-altitude environments?
A: Yes, the design can be modified with specific de-rating factors to operate reliably above 1,000 meters.
Q: How does the factory ensure raw material compliance?
A: All raw materials require MTCs. We conduct inbound sampling tests on copper conductivity, silicon steel core loss (W/kg), and resin viscosity before production release.
Q: How is the equipment protected against moisture during sea freight?
A: Transformers are enclosed in vapor-barrier bags (aluminum foil vacuum packaging) with calculated quantities of silica gel desiccants, then fixed inside IPPC-certified, ISPM 15 compliant seaworthy wooden crates.
Q: Are impact recorders installed during transit?
A: Yes, 3-axis impact recorders are attached to monitor structural acceleration and mechanical shocks during transportation.
