The high quality of the insulation used in modern conductors, in both enamelled winding wire and also in insulated polyester winding wire, reaches discharge value between the windings of over 6300 volts. For this reason, and due to the high quality in the stratification that can be obtained with the machine, high quality results have been achieved. Adopting this technique, over a period of 10 years, Siltech has produced more than 32,500 windings, which have been sold to various Italian and foreign customers, with an occurrence of only 0.4% of windings presenting breakdown during operation. Breakdown is due to dielectric low-voltage or ground failure. No breakdown has been identified due to dielectric turn-to-turn failure.
