Aluminium Transformer Foil 1060 O
In recent years, the output of transformers made of aluminum coils in China has been huge, and part of the phenomenon of using aluminum to pretend to be copper is prominent. Many people define transformers (distribution transformers) made of aluminum coils as "transformer fraud" and blame many transformer accidents on " It was caused by replacing copper with aluminum! It does obliterate the legitimacy of the product and its contribution at a specific historical stage.
The aluminum wire transformer made of aluminum foil is in line with national standards and is a product allowed by the country. It is also a product with international standards and a product recognized by developed countries.
According to statistics from the State Grid of China: my country's transformer market in 2019 is close to 500 billion yuan, and it is predicted to reach a market size of 600 billion yuan in 2025. The domestic copper price once reached 80,000 yuan/ton. The high cost put tremendous pressure on the market. The solution to the contradiction was to increase domestic copper mining and smelting. Facing a great pressure of environmental protection and energy consumption. At exactly this time, the transformer technology of aluminum coils in Western countries and Japan was introduced by domestic manufacturers (the price of aluminum at that time was only more than 10,000/ton). As early as the 20th century, the production of transformers in European countries also adopted a large number of aluminum coil solutions and mature technical standards. Up to now, aluminum core transformers are still being used in large quantities in Europe and America, and there is a huge stock market in Europe and the United States. Including Japan's Fuji, the domestic Suzhou industry has also been producing aluminum core transformers. Since the introduction of aluminum coil transformer technology into the country, the number of domestic small and medium transformer factories adopting this technology should be no less than a thousand. After more than ten years of optimization and technical upgrades, it has become a very mature product. Its appearance has solved the problem of copper materials. Tensions and energy-saving issues have also saved huge costs for the country’s infrastructure. From a technical point of view, aluminum coils for dry-type transformers cast with epoxy resin are better. Because the expansion coefficient of aluminum is closer to that of epoxy resin than copper, the safety of the transformer is better. Therefore, in Europe, most epoxy resin cast transformers use aluminum coils. As long as the manufacturing quality is good, the aluminum coil transformer will be no problem in use. my country has also issued the corresponding technical national standards for transformers with aluminum coils. For example, dry-type transformers with aluminum coils are marked as SCLB
