In an announcement Wednesday, the company said its new TRAN-COR  X family of steel represents a step improvement over its current TRAN-COR H steels and will help transformer manufacturers build higher efficiencies into their units.

“TRAN-COR X provides transformer manufacturers a significant improvement in efficiency over conventional high-permeability GOES at the same thickness. This avoids the use of harder to process thinner steels and allows transformer manufacturers to maintain production efficiencies while still improving transformer performance,” the company said.
