Aluminium Windings for Transformers 1050, 1060, 1070, 1350
Aluminum foil would transformer is a momentous value engineering breakthrough in the industry. The conventional copper wire is replaced by aluminium foil in transformer coil. It helps increase in its reliability and also reduces its overall material cost by 15 to 20 per cent.
