Acutran transformers are designed around different styles and grades of silicon steel cores: E & I Laminations, Strip Steel, C-Cores, and Distributed Gap Cores. Our designs which use E&I Laminations range from ½’’ to 5’’ in size. Both single- and three-phase laminations are stocked in 26/M50 and 29/M6 grades of steel.
Acutran also manufactures cores using Strip Steel from 1’’ up to 12” in width using M6, M4 and M3 grade Silicon Steel. We can also design our strip steel cores as a Mitered Core or as Distributed Gap Core, further offering superior efficiencies to meet the current DOE and CSA 802.2 efficiency requirements.
