Ripple oil tank of distribution transformer

The corrugated oil tank utilizes the "corrugated sheet folding machine" in the corrugated production line to automatically fold the cold-rolled steel sheet into the required sheet type according to the design drawings, including the corrugated height, pitch, corrugated sheet, straight edge length, and total length and width. Good folding quality and fast speed; After folding the corrugated sheet, it enters the welding process to complete the folding end seam and strengthen the iron welding. This welding process uses argon arc welding, which has stable welding arc, deep weld penetration, and good forming without defects. The corrugated fuel tank has a bottom, a rim, and a rectangular mailbox formed by welding corrugated plates in the middle. Corrugated sheets are made by folding thin plates. In addition to good heat dissipation performance during transformer operation, the corrugated fins of the corrugated sheets also have the function of expanding to alleviate internal pressure rise.
