Stator winding insulation |
摘要 |
A stator winding insulation for improving the dielectric and thermal properties of a main insulation of a conductor bar of an electric machine. The stator winding insulation includes a mica band having at least one layer-like carrier composed of longitudinal threads and transverse threads and a mica-containing layer fixed to at least one face of the carrier with the aid of a binder. In the layer-like carrier, the volume ratio of the longitudinal threads to the transverse threads is greater than or equal to 2.5:1 and a weight ratio of the mica in the mica-containing layer to the layer-like carrier in the mica band is greater than or equal to 6:1.
