Abstract: The stator winding insulation uses a mica band (11) with a carrier layer (4) provided with longitudinal and transverse threads (7a,7b), to which a layer (5) containing mica and a binder material is applied on at least one side. The volume ratio between the longitudinal threads and the transverse threads in the carrier layer is at least 2.5 : 1, the applied layer containing fine mica particles with a high packing density. The weight ratio of the mica particles to the carrier layer within the mica band is 6 or above.
