Tuboly-Astronic wire winding machine for 
instrument transformers type WHAN 150x3

Efficient semi-automatic wire winding machine for the production of medium and high voltage instrument transformer coils. 


The machine is prepared for winding up to 9 coils in parallel. Each wire is separately tensioned in a controlled wire brake device, the adjusted tension remains constant. An accurate wire guiding system allows fast and precise winding of the wires. 


The layer insulation is cut to the actual required total width. The waste paper strip is rolled up on a motor driven shaft. The insulation paper is automatically inserted to the coil and cut at correct length. Automatic positioned knives separate the coils from each other and two additional knives trim the outer ends of the coils.
