Factory Quality Control & Testing
| Quality Control & Inspection Item | Quality Proof & Objective Data |
|---|---|
| Power-Frequency Withstand Test | Routine tested at 35kV/5kV for 60s without insulation breakdown, per IEC 60076-3. |
| No-Load & Load Loss Measurement | Power analyzer tests confirm no-load losses are 15% lower than standard. |
| Temperature Rise Test | Full-load testing limits winding temperature rise strictly to under 65K. |
| Partial Discharge (PD) Measurement | At 1.5× rated voltage, partial discharge is strictly controlled below 10 pC. |
| High-purity transformer oil testing | Oil breakdown voltage exceeds 60 kV, guaranteeing long-term operational stability. |
| Enclosure protection & anti-corrosion | IP54 and salt spray tests prove zero leakage in harsh environments. |
Packaging & Logistics
- Transit Security The 100 Kva 3 Phase Transformer is anchored to an iron frame, preventing transit collisions.
- Stackable Freight Optimization The rigid frame allows double-layer stacking, maximizing container space to reduce client shipping costs.
- Forklift-Ready Base The integrated iron frame base features built-in slots for secure forklift and crane handling.

FAQ
Q: How does the factory verify the sealing integrity before delivery?
A: Every unit undergoes a 24-hour constant pressure oil leakage test at 0.05 MPa before packing.
Q: How is the transformer secured to prevent damage during sea freight?
A: The transformer's integrated iron base frame is bolted directly to the container floor or heavy-duty steel skids, supplemented by desiccant packs and heavy-gauge PE shrink wrap for ocean transit protection.
Q: What is the standard production lead time for a batch order?
A: The standard manufacturing and testing cycle takes 20 to 25 days from raw material sourcing to dispatch.
