Corrugated Walls
Corrugated walls for distribution transformers, manufactured on two fully automatic LAE pressing and welding machines. Super onda profile, spot welding, and strip applications.
About this product.
Convett has two fully automatic LAE corrugated walls pressing and welding machines for distribution transformers, with all the state of the art technologies. Manufacturing capabilities include corrugated walls with super onda profile, spot welding, and strip applications.
Following the indications on the customer’s drawings, all kinds of bending may be carried out, on either side of the wall or on the whole wall, so that the tank construction may be completed with only one weld. Convett has already manufactured corrugated walls for 6 MVA transformers, with a single-side corrugated wall weighing 1,000 kg.
