Abstract

Die Erfindung betrifft eine Elektrisches Sektorleiterkabel vom Millikentyp, bei dem der runde Leiter in mehrere, vorzugsweise fünf oder sechs, Segmente (10) geteilt ist, die gegeneinander isoliert verseilt sind, und jedes Segment (10) aus mehreren Lagen (12,14) von verdichteten, strangförmigen Einzelleitern (30) besteht, die um ein Kabel-Zentrum mit unterschiedlichen Schlaglängen verseilt sind. Jedes Segment (10) besteht aus einem Kern (11) mehrerer nicht isolierter Einzelleiter (30), und auf dem Segmentkern (11) sind mindestens zwei Lagen (12,14) von strangförmigen Einzelleitern (30) aufgebracht. Die auf dem Segmentkern (11) aufgebrachte erste Lage (12) ist gegen den Segmentkern (11) durch eine Isolierschicht (16) getrennt und die weiteren aufgebrachten (zweite und weitere) Lagen (14) sind ebenfalls gegeneinander durch eine Isolierschicht (20) getrennt. In den auf den Segmentkern (11) aufgebrachten Lagen (12,14) sind neben den Einzelleitern (30) weitere nicht-leitende Elemente (40,42) vorhanden, deren Querschnitt ein Bruchteil des Querschnitts der Einzelleiter (30) ausmacht.

The invention relates to a mill-type electric sector conductor cable in which the round conductor is divided into several, preferably five or six, segments (10) which are stranded isolated from each other, and each segment (10) consists of several layers (12, 14) of FIG compacted, strand-shaped individual conductors (30), which are stranded around a cable center with different lay lengths. Each segment (10) consists of a core (11) of several non-insulated individual conductors (30), and on the segment core (11) at least two layers (12,14) of strand-shaped individual conductors (30) are applied. The first layer (12) applied to the segment core (11) is separated from the segment core (11) by an insulating layer (16) and the further applied (second and further) layers (14) are also separated from one another by an insulating layer (20) , In the layers (12, 14) applied to the segment core (11), in addition to the individual conductors (30), there are further nonconductive elements (40, 42) whose cross section constitutes a fraction of the cross section of the individual conductors (30).
