Winding .
The winding must be especially protected - both against high electrical stress due to
external over voltages and against mechanical overloads by short circuits. They are made of copper or aluminum. Low-voltage windings are made of strip or flat wire while
high voltage windings are manufactured from round or profile wire. ("diamond-dotted paper") bonds the winding into a compact block
while drying and increases the short-circuit capacity additionally.
