ABSTRACT:
The conductor bars of stator windings of rotating electric machines are usually multiply wound around with two-layer mica strips as major insulation and then impregnated with synthetic resin. It is proposed to use as first layer (L1) a mica strip which is provided on both sides with a textile carrier (24, 25). The further layers (L2, L3, L4, . . .) are then wound with a mica strip (27) provided with a textile carrier (28) only on one side. A major insulation constructed in this way is very homogeneous. The textile carrier (24), preferably consisting of glass fabric, which bears directly on the conductor surface, optimizes the impregnation and produces an effective bond between the insulation and conductor.
