Tape winding machine AB series

mobileautomaticmotorized

Overview
This strip-type winding machine (models AB 450–AB 1000) is designed to produce windings directly on the resin casting mould for resin-encapsulated medium-voltage transformers. It accepts aluminium and copper strip conductors and supports coils up to 1700 mm in height. The integrated control system ensures repeatable winding quality and synchronized handling of conductor and insulation paper.
