❓ Frequently Asked Questions
Q1: Does your factory hold international quality certifications?
Yes, our facility is ISO 9001 certified. 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 your annual production capacity?
We operate a modern production base with an annual capacity exceeding 10,000 units, ranging from 30KVA to 20MVA for both oil-immersed and dry-type transformers.
Q3: How is product quality ensured before shipment?
Quality is controlled at every stage: strict raw material inspection, quality control points at critical production phases, and rigorous factory testing for every unit with provided test reports.
Q4: What is the difference between your copper and aluminum windings?
Copper windings offer higher conductivity, better efficiency, and longer lifespan but at a higher cost. Aluminum windings are a lighter, cost-effective alternative that is fully qualified for many projects.
Q5: What are the standard delivery lead times?
Standard small transformers typically take 15-30 days, while large or customized units may require 45-90 days depending on the specifications and quantity.
Q6: What kind of after-sales technical support do you provide?
We offer a 12-month warranty, remote technical assistance via video/email, long-term spare parts supply, and on-site engineering services if required.
