Corrugate fin is a important part in the transformer cooling system. it is made of special cold-rolled MS coils, which are directly welded to form transformer oil tank.These fins are flexible enough to absorb the volume expansion of liquid (insulating oil) and provide a large surface area for heat dissipation.Compared with ordinary transformer, it has low height and small volume.

The transformer oil tank is composed of corrugated walls. The corrugated radiator not only has the cooling function but also has the “breathing” function. Its elasticity can compensate for the change of transformer oil volume caused by temperature rise and fall.

During the general assembly of the transformer, the vacuum oil injection process is used to completely remove the moisture in the transformer. The transformer oil is not in contact with the air, effectively preventing oxygen and water from invading the transformer, resulting in the transformer insulation performance degradation and the aging of the transformer oil.

we have automaticly corrugate fin forming maching and automatic welding machine to ensure each piece of fins are well welded.we are supplying the corrugate fin withthe material MS steel and Stainless steel.
