Why does the transformer foil winding machine limit the thickness of aluminum foil? How to increase the thickness of aluminum foil?

Foil winding, aluminum foil to be tensioned, in order to maintain a certain tension, smooth, flat winding coil, the thicker the aluminum foil requires greater tension, the maximum tension of the coil winding machine is limited, exceeding the maximum tension of the machine is dangerous, the tension is too small winding coil loose, can not ensure the size requirements. Therefore, here is not to say that you want to increase the thickness of aluminum foil, because transformer designers for the thickness of aluminum foil, section, current density, temperature rise, etc., can be considered as a whole, rather than blindly adjust the thickness to design and calculate the winding characteristics of the transformer.

Q:

Thank you very much for your analysis and answer. The original foil winding machine for the thickness of the aluminum foil is 2. Only 0, but if necessary, must be increased to 2.5. What is the easiest way to modify the foil winding machine?

A:

1. You’d better buy some soft aluminum foil. Aluminum foil is available in several hard and soft specifications. You can consult the aluminum foil supplier.
2. If 2.5mm foil must be used to wrap the machine nameplate, the thickness of aluminum foil on the machine nameplate is only allowed to be 2mm, and the machine’s super nameplate data will run, and the accident may not damage the machine itself. If you have a large number of platforms, it is recommended to add a set of compression aluminum foil devices under the winding die, while maximizing the tension of the machine, and then help the coil winding with the pressure of the coil roller.
3. I also encountered this problem. The thickness increased to 2.5mm and the width of aluminum foil increased beyond the allowable range of the foil winding machine.
