Claims (1)

Проводящие стержни статорных обмоток вращающихся электрических машин обматывают обычно несколько раз двухслойными миканитовыми лентами в качестве главной изоляции. Предложено применять в качестве первого слоя миканитовую ленту, снабженную с обеих сторон одной текстильной основой. Другие слои наматывают из миканитовой ленты, снабженной текстильной основой только с одной стороны. Подобная главная изоляция очень однородна. Прилегающая непосредственно к поверхности проводника текстильная основа, предпочтительно стеклоткань, оптимизирует процесс пропитки и обуславливают хорошее склеивание между изоляцией и проводником.The conductive rods of the stator windings of rotating electrical machines are usually wound several times with double-layer micanite tapes as the main insulation. It is proposed to use as a first layer a micanite tape, provided on both sides with one textile base. Other layers are wound from micanite tape, provided with a textile base on one side only. Similar main insulation is very uniform. Adjacent to the surface of the conductor textile base, preferably fiberglass, optimizes the impregnation process and cause good adhesion between the insulation and the conductor.
