Frequently Asked Questions

Q: What's the difference between AN and AF cooling methods?

A: AN (Air Natural) uses self-cooling for standard loads. AF (Air Forced) adds fans for applications requiring higher capacity or operating in high-temperature environments. You can choose based on your load conditions.

Q: Can I use this transformer outdoors?

A: The SC(B)14 series is designed for indoor installations. If you need outdoor solutions, we recommend our weatherproof enclosure options or oil-immersed transformers.

Q: What does the "B" in SC(B) mean?

A: The "B" indicates copper foil low-voltage windings, which offer better thermal performance and current distribution compared to aluminum windings. It's the preferred choice for reliability.

Q: How long does delivery take?

A: Standard configurations ship in 6–15 days. Custom specifications typically require 15–30 days. We'll provide exact timelines when you share your requirements.

Q: What documentation do you provide?

A: You receive complete technical drawings, operation manuals, factory test reports, and certification documents. We also provide installation guidance and spare parts recommendations.

Q: Is voltage customization available?

A: Yes. While 10kV is standard, we customize voltage ratings and taps to match your grid requirements. Just let us know your specifications.
