The corrugated sheet in oil immersed transformers plays a crucial role as a key component. It first ensures the stability of the transformer oil level through its elastic deformation characteristics, avoiding damage to the transformer caused by oil level fluctuations. Secondly, the corrugated sheet acts as a precise filter, effectively blocking the entry of gas and water into the interior of the transformer, maintaining the purity and stability of the transformer oil.

Furthermore, its unique sealing design can prevent transformer oil from leaking from the oil tank connection, ensuring the safe operation of the transformer. In summary, the corrugated sheet not only stabilizes the oil level and filters impurities in oil immersed transformers, but also prevents oil leakage, making it an essential component for ensuring the safe and reliable operation of transformers.

The design principle of corrugated sheets is mainly to use their unique corrugated structure to increase surface area and strength, while guiding fluid flow. In oil immersed transformers, the corrugated sheet, through its corrugated shape, can effectively disperse the pressure of the oil, maintain the stability of the oil level, and help with heat dissipation.

In addition, the design of corrugated sheets also needs to consider factors such as the durability, deformation resistance, and compatibility with transformer oil of their materials.
