Product Q&A
Q:Does your company hold any relevant international quality certifications?
A:
Yes, our factory is ISO 9001 Quality Management System certified. Our products comply with international standards such as IEC (International Electrotechnical Commission) and CE. We can also apply for certifications specific to other countries upon customer request.
Q:What is your factory's production capacity? What is the annual output?
A:
We operate a modern production base with advanced production lines. Our annual production capacity exceeds 10,000 units. We manufacture oil-immersed and dry-type transformers ranging from 30KVA to 20MVA.
Q:How do you ensure product quality?
A:
Our quality assurance spans the entire process: Source Control: Strict supplier screening and incoming inspection of raw materials. Process Control: Quality control points established at critical production stages. Final Inspection: Each transformer undergoes rigorous factory testing before shipment, with test reports provided.
Q:What types of transformers do you primarily manufacture?
A:
We mainly produce: Oil-immersed transformers: Suitable for outdoor, power plant, and large industrial projects, offering a wide power range and high cost-effectiveness. Dry-type transformers: Ideal for indoor, commercial buildings, hospitals, data centers, and other locations with high fire safety requirements.
Q:What are the primary materials for transformers? Are windings copper or aluminum?
A:
We offer both materials: Copper windings: Higher conductivity, better efficiency, smaller size, high mechanical strength, longer lifespan, but higher cost. Aluminum windings: Lower cost, lighter weight, fully qualified alternative material. We recommend clients select suitable materials based on project budget, efficiency requirements, and long-term operational costs.
