A3: How do you ensure product quality?
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.
B. About Products & Technology
B1: What types of transformers do you primarily manufacture?
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.
B2: What are the primary materials for transformers? Are windings copper or aluminum?
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.
