FAQ
Q: What is the difference between S11 and S13 series?
A: The S13 series has lower no-load loss and higher energy efficiency compared to S11, meeting stricter energy-saving standards. Both are suitable for 10kV distribution, but S13 is recommended for projects prioritizing long-term energy savings.
Q: Can I get a custom voltage rating?
A: Yes, Sanlita offers customization for primary and secondary voltages, tap changers, and accessories. Please provide your specific requirements for a tailored solution.
Q: What is the typical lead time for this transformer?
A: Standard models (100-630KVA) typically ship within 15-25 working days after order confirmation. Custom orders may require additional time depending on complexity.
Q: Do you provide test certificates?
A: Absolutely. Each transformer comes with a factory test report. Third-party inspection (e.g., SGS, BV) is also available upon request.
Q: How is the transformer packaged for export?
A: Transformers are securely packed in wooden crates with moisture-proof lining, suitable for sea or air freight. Lifting lugs and documentation are included.
