Transformer corrugated wall

Transformer corrugated wall is a core heat dissipation and protection component for oil-immersed transformers. It is made of high-quality cold-rolled steel plates through precision forming technology, featuring a corrugated structural design. Its primary function is to rapidly dissipate the heat generated by the iron core and windings during operation to the environment through heat exchange between the corrugated cavity and transformer oil. Meanwhile, it hermetically isolates external moisture, dust, and other impurities to ensure the stable insulation performance inside the transformer.

Compared with traditional heat dissipation structures, the corrugated wall has distinct advantages: the one-piece forming process eliminates welding seams, providing superior sealing performance and effectively reducing the risk of oil leakage; the elastic design of the corrugated structure can absorb thermal expansion and contraction stresses during transformer operation, extending the equipment's service life; no additional heat dissipation devices are required, simplifying the product structure while reducing energy consumption.

The specifications of corrugated walls are customized according to transformer parameters such as capacity and rated temperature rise. Common materials include Q235 cold-rolled steel and stainless steel, with surfaces treated by anti-rust painting or galvanizing to adapt to various application scenarios such as outdoor and industrial workshops. As a key transformer accessory, its heat dissipation efficiency and structural stability directly affect the operational reliability and service life of transformers, making it an essential component for ensuring the safe and efficient operation of power equipment.
