The invention relates to an electric conductor (3, 12) which is arranged in an encapsulation casing (2, 11) and insulated by means of support insulators (4a, b) inside said encapsulation casing (2, 11). Said electric conductor (3, 12) has a high-voltage potential and the encapsulation casing (2, 11) has the earth potential and is provided with a particle trap (5, 13, 14) which makes it possible to bind foreign particles (8a, b) in the encapsulation casing. The distance between the electric conductor (3, 12) and the encapsulation casing (2, 11) gradually reduces within a segment (6, 7, 15, 16) which is arranged therebetween. Said particle trap (5, 13, 14) is disposed in the segment (6, 7, 15, 16) at a smallest distance between the electric conductor (3, 12) and encapsulation casing (2, 11). |
