The power transmission industry in China is rapidly evolving, and Oil immersed transformers are playing an increasingly important role in this transformation. As the demand for reliable and efficient power transmission continues to grow, Oil immersed transformers are becoming an increasingly attractive option for many power transmission projects.
Oil immersed transformers offer a number of advantages over traditional air-cooled transformers, including improved efficiency, increased reliability, and reduced maintenance costs. These benefits make Oil immersed transformers an ideal choice for many power transmission projects in China.
The improved efficiency of Oil immersed transformers is one of the most attractive benefits. By using oil as a cooling medium, Oil immersed transformers are able to operate at higher temperatures than air-cooled transformers, resulting in higher efficiency. This increased efficiency can result in significant cost savings over the life of the transformer.
In addition to improved efficiency, Oil immersed transformers also offer increased reliability. The oil used in these transformers acts as an insulator, protecting the transformer from electrical faults and other potential damage. This increased reliability can help reduce the risk of costly downtime and repairs.
Finally, Oil immersed transformers require less maintenance than air-cooled transformers. The oil used in these transformers is self-lubricating, meaning that it does not need to be replaced as often as air-cooled transformers. This can result in significant cost savings over the life of the transformer.
The benefits of Oil immersed transformers make them an ideal choice for many power transmission projects in China. By offering improved efficiency, increased reliability, and reduced maintenance costs, Oil immersed transformers can help reduce costs and improve the reliability of power transmission projects. As the demand for reliable and efficient power transmission continues to grow, Oil immersed transformers will continue to play an increasingly important role in the transformation of the power transmission industry in China.
The manufacturing process of Oil immersed transformers in China is a complex and intricate process that requires a great deal of skill and precision. It is a process that has been perfected over the years, and it is one that has enabled China to become a leader in the production of transformers.
The process begins with the selection of the raw materials. The materials used in the production of transformers must be of the highest quality in order to ensure the best possible performance. The materials are then cut and shaped to the exact specifications of the transformer.
Once the materials have been cut and shaped, they are then assembled into the transformer. This is done by carefully connecting the various components of the transformer, such as the core, windings, and insulation. This process requires a great deal of skill and precision, as even the slightest mistake can lead to a malfunctioning transformer.
The next step in the process is the testing of the transformer. This is done to ensure that the transformer is functioning properly and that it meets all of the necessary safety standards. Once the transformer has passed all of the tests, it is then ready to be filled with oil.

The oil is then heated to a specific temperature and then poured into the transformer. This is done to ensure that the transformer is completely sealed and that no air can enter the transformer. Once the transformer is filled with oil, it is then ready to be tested again to ensure that it is functioning properly.
The manufacturing process of Oil immersed transformers in China is a complex and intricate process that requires a great deal of skill and precision. It is a process that has been perfected over the years, and it is one that has enabled China to become a leader in the production of transformers.
