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.
