FAQ
Q: What routine factory tests are performed on the 800 kVA Dry Type Transformer before dispatch?
A: Every unit undergoes insulation resistance, voltage ratio, winding resistance, and partial discharge testing at our factory.
Q: How is the 800 kVA Dry Type Transformer secured during international ocean freight?
A: It is packed in IP23-rated seaworthy wooden cases with internal vacuum moisture-barriers and heavy-duty base tie-downs.
Q: Can the 800 kVA Dry Type Transformer handle short-term overloads?
A: Yes, when equipped with forced air cooling (AF), it can operate up to 120% rated capacity continuously.
Q: What is the standard manufacturing lead time for this specific 800 kVA unit?
A: The standard factory production cycle is 25 to 30 days from final technical drawing approval.
Q: Does the enclosure design allow for flexible high-voltage and low-voltage cable routing?
A: Yes, the enclosure features removable gland plates configured for either top or bottom cable entry.
