The high quality of the insulation used in modern conductors, both in enameled wire and polyester-taped wire, achieves insulation values between windings of over 6300 volts. For this reason, thanks to the high-quality layering that can be achieved with the machine, high-quality results have been obtained. By adopting this technique, over a ten-year period, Siltech has produced more than 32,500 windings, which have been sold to various Italian and foreign customers, with a failure rate of only 0.4% during operation. The failures were due to low dielectric voltage or ground faults. No failures have been identified due to dielectric failure between the windings.
