Description

Bewehrung für Einleiter-Wechselstromkabel. Es ist bereits bekannt; die Bewehrung von Einleiter-Wechselstromkabeln aus nicht magnetisierbarem Material herzustellen, weil dadurch in ihr Energieverluste durch Hysterese vermieden und diejenigen durch Wirbelströme stak herabgemindert werden. Als für diesen Zweck geeignete, nicht magnetisierbare Materialien sind bisher Aluminium, Kupfer und verschiedene Bronzen vorgeschlagen worden. Erfindungsgemäß wird als Bewehrungsmaterial für Einleiter-Wechselstromkabel, und zwar für Stark- und Schwachstromkabel, eine der an sich bekannten stark eisenhaltigen Legierungen mit solchem Gehalt an anderen Metallen, und zwar vorzugsweise Nickel, Mangan und Chrom, verwendet, daß sie unmagnetisierbar oder wenigstens nur äußerst schwach magnetisierbar ist. Besonders geeignet für den erfindungsgemäßen Zweck sind beispielsweise zwei an sich bekannte Legierungen. ungefähr folgender Zusammensetzung: Fe Ni Mn Cr 1. 73 8 1 18 Prozent 2. 8o 13 5 2 _ Außerdem enthalten die Legierungen noch geringe Beimengungen von Kohlenstoff, Phosphor, Schwefel und Silicium.Armouring for single-core AC cables. It is already known; to produce the armouring of single-conductor AC cables from non-magnetizable material, because this avoids energy losses due to hysteresis and those due to eddy currents are greatly reduced. As non-magnetizable materials suitable for this purpose, aluminum, copper and various bronzes have heretofore been proposed. According to the invention, one of the known strong ferrous alloys with such a content of other metals, preferably nickel, manganese and chromium, that they are non-magnetizable or at least only extremely, is used as armouring material for single-conductor AC cables, specifically for high-voltage and low-voltage cables is weakly magnetizable. For example, two alloys known per se are particularly suitable for the purpose according to the invention. approximately the following composition: Fe Ni Mn Cr 1. 73 8 1 18 percent 2. 8o 13 5 2 _ The alloys also contain small amounts of carbon, phosphorus, sulfur and silicon.

Diese beiden Legierungen haben, wie gleichfalls bereits bekannt, eine Permeabilität von nur etwa 1,5 und zeichnen sich gegenüber den bisher als Bewehrungsmaterial gebräuchlichen nicht magnetisierbaren Materialien durch große Festigkeit aus.As already known, these two alloys have one Permeability of only about 1.5 and stand out over those previously used as reinforcement material common non-magnetizable materials are characterized by great strength.
