Corrugated walls for electrical transformers
SARI thanks to the experience of its founder in the construction of molds, in 1988 he built his first machine for the production of corrugated walls, patenting one of the first production systems in Europe in the same year.
Immediately thereafter, in 1989, he patented his reinforcement system, the primary basis for the creation of new models that have evolved over the years.
Over the years, the experience gained, supported by new technologies, has allowed us to build ever more precise and faster systems, managing to meet the new market needs starting from the reinforcement drawing with or without spot welding, already from the first plants, and ending with the SUPER WAVE and STRIP version with 4.0 management.
Corrugated walls can be produced with heights starting from 400 mm with multiples of 50 mm up to 1000 to arrive with multiples of 100 mm to the largest size of 1600 mm.
The thicknesses always available are 1.0 mm – 1.2 mm – 1.5 mm.
The wall depth is from a minimum of 4 0mm to a maximum of 500 mm.
In larger depths it is possible to apply from one to three reinforcements that make the wave more rigid and to avoid swelling it is possible to carry out welding points inside them.
Finally, to facilitate the carpenter’s work, it is possible to supply the corrugated walls in 1-2, 3 or 4 pieces joined by folding them successively with appropriate equipment thus reducing the number of welds.

REINFORCEMENT STRIP
On request it is possible to apply a 15 mm x 1.18 mm metal strip on all corrugated walls with welding spots.
This application facilitates the welding work of the case and at the same time on large walls allows to strengthen the system.
SUPER WAVE VERSION
The super wave was created to compensate for the amount of oil inside the case which is decreased by the presence of the reinforcement drawing.
Pockets have been created at the ends of the panel which, in addition to being able to contain more oil, facilitate the circulation of the same, allowing greater heat dissipation.
Rod
Our systems allow you to insert and weld automatically a double reinforcing rod being able to choose between the diameter 6 – 7 and 8 mm.
PACKING
The packaging is carried out with particular attention in order to protect the product and at the same time to optimize spaces, building, given the variety of product sizes, custom-made pallets in order to facilitate the loading of containers and trucks.
We also have pallets with phytosanitary marking.
To optimize the spaces, you can also request a specific packaging, inserting the walls one inside the other by applying only a rod.
Upon request, the second coupling rod can be supplied separately.
