Transformer Construction of the Core:
Introduction of oil tank：
Corrugated oil tank uses the "corrugated sheet folding machine" in the corrugated production line to automatically fold the specification of cold-rolled steel coil into the sheet type required by the design drawing, including the corrugated height, pitch, corrugated sheet, straight edge length and total length and width of corrugated sheet. The folding quality is good and the speed is fast; the corrugated sheet is welded after folding to complete the folding end seam and reinforced iron welding. The welding adopts argon arc welding, with stable welding arc, large weld penetration, good forming, and no defects. The corrugated oil tank has a bottom, a box edge, and a rectangular mailbox made of corrugated sheets. The corrugated sheet is made of folded sheet. In addition to good heat dissipation performance, the corrugated fin has the function of expansion to relieve the internal pressure rise.
