Toroidal transformer is manufactured on a high-speed automatic winding machines, enjoys an ideal physical construction with the minimum of material. Thanks to toroidal Core consists of idea grain oriented silicon steel strip and is wound into circular shape, leakage flux can be restricted to a minimum level and a higher percentage of the magnetic flux of toroidal transformer is being put to much more effective use, achieving much higher electrical efficiencies than conventional EI laminated tran... >>
