6kv 10kv 800kVA ISO Certified Oil Immersed Transformer

Yes, our factory is ISO 9001 Quality Management System certified. Our products comply with international standards such as IEC and CE. We can also apply for certifications specific to other countries upon customer request.

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.

Our quality assurance spans the entire process: Source Control involves strict supplier screening and incoming inspection of raw materials. Process Control establishes quality control points at critical production stages. Final Inspection ensures each transformer undergoes rigorous factory testing before shipment, with test reports provided.

We mainly produce Oil-immersed transformers suitable for outdoor, power plant, and large industrial projects, offering a wide power range and high cost-effectiveness. We also produce Dry-type transformers ideal for indoor, commercial buildings, hospitals, data centers, and other locations with high fire safety requirements.

We offer both materials. Copper windings provide higher conductivity, better efficiency, smaller size, high mechanical strength, and longer lifespan, but at a higher cost. Aluminum windings offer lower cost and lighter weight as a fully qualified alternative material. We recommend clients select suitable materials based on project budget, efficiency requirements, and long-term operational costs.
