Abstract

Изобретение относится к изолированному проводнику (10) для высоковольтных обмоток в электрических машинах. Изолированный проводник (10) содержит одну или более жил (12), первый внутренний проводящий слой (14), окружающий жилы (12), первый изолирующий слой (16), окружающий первый внутренний проводящий слой (14), и второй внешний проводящий слой (18), окружающий первый изолирующий слой (16). Второй проводящий слой (18) имеет удельное сопротивление, которое, с одной стороны, уменьшает электрические потери в этом слое, а с другой стороны, вносит вклад в напряжение, индуцированное в этом втором проводящем слое (18), уменьшая опасность возникновения тлеющих разрядов.Международная заявка была опубликована вместе с отчетом о международном поиске.
