In inverter-fed motors mechanism of degradation of insulation is changed. Apart from thermal ageing a degradation due to short voltage pulses have occurred. One of the main reasons of deterioration of organic insulation of low voltage inverter driven motors are partial discharges, which appeared under pulse voltage. Standard enamelled wires are not resistance to these exposure and insulation systems are usually oversized. Based on nanotechnology the new special enamel for winding wires with improved endurance to partial discharges has been developed in Electrotechnical Institute in Wroclaw with cooperative with Polifarb Cieszyn-Wroclaw. In the paper the results of the testing of dielectric properties (breakdown voltage and resistance to sine and pulse voltage) of the new winding wire enamelled with the special enamel have been presented. The new special enamelled wire spent requirements of standard PN-EN 60317-8 while its resistance to partial discharges is at least 100 times better then resistance of conventional winding wire.
