SamicaRound-an electrical insulation system for high-voltage motors with round wire windings up to 6.6 kV

Electrical motors made with round wire can be manufactured at lower costs and with minimized technological effort compared to machines with preformed windings. Whereas round wire windings are mostly applied in low-voltage machines, preformed windings are used for high-voltage motors. The development of the SamicaRound electrical insulation system enables motors of the traditional low-voltage design to operate up to 6.6 kV. The goal of the tests presented in this paper was to prove the suitability of the SamicaRound insulation system for rated voltages up to 6.6 kV and to determine the respective application thereof.
