Frequently Asked Questions

Does the factory hold international quality certifications?

Yes, our manufacturing base is ISO 9001 Quality Management System certified. Products comply with international standards such as IEC and CE. Specific certifications for different regions can be applied for upon request.

What is the annual production capacity for transformers?

We operate modern production lines with an annual capacity exceeding 10,000 units. We manufacture a wide range of oil-immersed and dry-type transformers from 30KVA up to 20MVA.

How is product quality ensured during manufacturing?

Quality is managed through strict supplier screening for raw materials, established QC points at every critical production stage, and a final rigorous factory test for every unit before shipment.

What are the differences between Copper and Aluminum windings?

Copper windings offer higher conductivity, better efficiency, and a longer lifespan but come at a higher cost. Aluminum windings are a lightweight, cost-effective alternative that is fully qualified for many distribution needs.

What is the typical delivery lead time for orders?

Standard small transformers typically take 15-30 days. For large-scale or highly customized units, the lead time ranges from 45 to 90 days depending on the technical specifications.

How are the transformers protected during international shipping?

We use specialized packaging including sturdy wooden crates with internal moisture-proofing for LCL shipments. For FCL, units are securely fastened directly inside the container to withstand long-distance ocean transport.
