Frequently Asked Questions

Q1: Do your products hold international quality certifications?

Yes, our facilities are ISO 9001 certified, and our products comply with international standards such as IEC (International Electrotechnical Commission) and CE. We can also provide country-specific certifications upon request.

Q2: What is the annual production capacity for transformers?

We operate modern production lines with an annual capacity exceeding 10,000 units, ranging from 30KVA to 20MVA for both oil-immersed and dry-type transformers.

Q3: How do you ensure the quality of each unit?

Quality is ensured through a three-step process: Strict raw material screening (Source Control), quality checkpoints at critical production stages (Process Control), and rigorous factory testing with full reports before shipment (Final Inspection).

Q4: What types of transformers are available in your catalog?

We primarily manufacture Oil-immersed transformers (ideal for outdoor and industrial projects) and Dry-type transformers (perfect for indoor environments like hospitals and data centers with high fire safety needs).

Q5: What winding materials do you use?

We offer both Copper and Aluminum windings. Copper provides higher conductivity and mechanical strength, while Aluminum offers a more cost-effective solution for specific applications.

Q6: Is the XGW12 RMU suitable for harsh outdoor environments?

Absolutely. With an IP4X protection rating, stainless steel shell material, and wide temperature tolerance (-25°C to +40°C), it is specifically designed for stability in urban grids and industrial outdoor substations.
