Our press machine has the capability to make a new profile of the corrugated wall which facilitate the oil circulation inside the walls. In fact this new profile which we call “SUPER ONDA” has the upper part and the bottom part of the corrugated thin with a larger profile (internal gap is about 12mm instead of 6mm). This profile creates a bigger section where the oil circulate, and it increase the quantity of hot oil which pass through the wall per minute. This higher performance allow you to optimize the corrugated walls profile, because you have some temperature and dissipation advantages compared to the “normal profile” which can helps your engineering departments to save on the transformers raw materials and costs.
