Frequently Asked Questions (FAQs)

Frequently Asked Questions About Aluminium Transformer Factories in China

What are the key steps in the manufacturing process of aluminium transformers in China

The manufacturing process involves several crucial steps. It starts with design and planning, where engineers tailor the transformer to meet specific customer requirements. This is followed by material preparation, where high-quality materials like iron cores, coils, and insulation materials are sourced. The core is then processed, and coils are wound with precision. After the first assembly, the core is dried to improve insulation properties, and finally, the core is placed into the tank with the necessary accessories installed.

Why do Chinese factories use aluminium foil in transformer windings

Aluminium foil is used in transformer windings because it offers several advantages. It results in smaller, lighter transformers with good insulation properties. Aluminium foil is also flame retardant, non-polluting, and resistant to moisture, ensuring smooth and reliable operation. Additionally, it helps in reducing the overall size and weight of the transformer, making it more efficient and easier to handle.

How do Chinese factories ensure the quality and reliability of aluminium transformers

To ensure quality and reliability, Chinese factories like CHINT and Daelim employ rigorous testing and assembly processes. Transformers undergo thorough tests, including partial discharge testing and simulations of extreme conditions like lightning strikes. The factories also adhere to international standards, with products passing tests such as those from KEMA. Moreover, they maintain high precision in manufacturing, using advanced automation and precise coil winding techniques.

What are the geographical advantages of locating aluminium transformer factories in China

Factories located in strategic areas like Wuhan and Shanghai benefit from their proximity to major transportation hubs. For example, the Wuhan factory is near Yangluo Port on the Yangtze River, which connects to international destinations via integrated river and rail systems. This facilitates efficient global distribution and reduces logistics costs, making the products more competitive in the global market.

How do Chinese aluminium transformer factories contribute to environmental sustainability

Chinese aluminium transformer factories are increasingly focused on green manufacturing. For instance, CHINT’s factories in Wuhan and Shanghai are models of environmental sustainability. They use advanced manufacturing processes that minimize waste and energy consumption. The factories also employ green technologies and materials, such as natural ester-insulating oil transformers, to reduce their environmental footprint and contribute to a more sustainable future.
