finned radiators are the main cooling component of the power transformers and special transformers.

the high efficiency finned radiator’s cooling element is manufactured by automatic punching, combining, drop sew-welding and edge cutting with high quality cold rolled steel sheets. We use outside co2 protection welding to do the connection between elements and oil collection pipe.

this technique could avoid the welding residue or iron scrap produced by inner welding, which will affect the heat transfer performance and quality of the radiator. Also the finned radiator will be strictly checked with sealing test and hot oil flushing, its surface with hot-dip galvanizing and painting, to guarantee the product quality.

the finned radiator fully meets the transformer industry standard jb/t 5347 and bs-en 50216-6 when tested by third-party inspection institute.
