<p>In a line transformer for a television receiver in which the start and end of the primary winding (4) end at the same end of the coil former (15), an insulating film is required between the two partial windings (4a, 4b) to achieve the necessary dielectric strength. Moreover, it is necessary to ensure that the cast mass (17) penetrates satisfactorily into the intermediate spaces of the turns of the primary winding (4). To save insulating film, and to improve the penetration of the cast mass (17), the coil former (15) is provided with axially running grooves (16) on its surface through which the cast mass (17) can flow. <IMAGE></p> |
