Cable for use in transformer or dynamoelectric machine, insulation layer between two semiconducting layers

摘要

This electromagnetic device comprises a magnetic field generating an electrical circuit including a winding (1) having at least one electrical conductor (2). The winding comprises a solid insulation (4) surrounded by outer and inner layers (3, 5) serving for equalization of potential and having semiconducting properties. The at least one electrical conductor (2) is arranged interiorly of the inner semiconducting layer (3). The application also relates to methods for electric field control and production of a magnetic circuit as well as use of a cable for obtaining a winding.
