Description
Kunststoffisoliertes Einleiter-Energiekabel, insbesondere Mittelspannungskabel Einleiter-Energiekabel, die für Mittel- oder Hochspannung ausgelegt sind, weisen in der Regel einen metallischen Schirm auf, der auf der Kunststoffisolierung des IPZters aufgebracht ist und aus aufgesponnenen Drähten oder Metallbändern, vorzugsweise aus Kupfer, besteht. Dieser metallische Schirm, der beim verlegten Kabel mit '^rde verbunden ist, dient allein dem elek-#trsehen Berührungsschutz lind ist in seinem Querschnitt und damit in seiner Strombelastbarkeit den Verhältnissen der üblichen Mittel.- oder HoQhspannungsnetze angepaßt. Durch einen. Kunststoffmantel ist der metallische Schirm gegen Korrosion geschützt.Plastic-insulated single-conductor energy cables, in particular medium-voltage cables Single-core power cables, which are designed for medium or high voltage, have usually a metallic screen that is placed on the plastic insulation of the IPZters is applied and made of spun wires or metal strips, preferably made of copper. This metallic screen, which with the laid cable with '^ rde is connected, is used only for the electrical # contact protection lind is in his Cross-section and thus in its current carrying capacity the ratios of the usual Medium or high voltage networks adapted. Through a. Plastic jacket the metallic screen is protected against corrosion.
Bei mechanischen Beanspruchungen des Kabels, beispielsweise . . beim Transport oder beim Verlegen, kann es jedoch vorkommen, daß sieh die einzelnen Drähte oder Bänder-längs des Umfangeo des Kabels verschieben, so daß ein solcher aus Drähten oder Metallbändern be stehender Schirm diP Oberfläche der Ieiterisolierung nur in unzureichender ;Meise bedeckt und somit keine dichte Umhüllung mehr gebildet wird. buch ist bei diesem bekannten Kabel das anschließen des metallischen Schirme: an eine Erdungsklemme zeitraubend, da jeder einzelne Draht an der -Anschlußstelln verlcitrt werden muß.In the event of mechanical stresses on the cable, for example. . at the Transporting or laying, however, it can happen that you see the individual wires or straps-shift along the circumference of the cable, so that one made of wires or metal straps existing screen diP surface of conductor insulation only in inadequate; tit covered and thus no more tight covering is formed. The book of this well-known cable is the connection of the metallic screen: to A grounding clamp is time-consuming, as every single wire is left at the connection point must become.
Durch die Erfindung wird eine einfachere Abschirmung eines kunststoffisolierten
Einleiter-Energinkabelgeschaffen. Gemäß der Erfindung besteht der metallische Schirm
aus einem längs-1 verlaufenden, um die Kunsto toffisolierung des Leiters herumgefalteten
Metallband, vorzugsweise aus kupfer, dessen Kanten einander überlappen. Hierdurch
-ist- eine einwandfreir^ Bedeckung der Oberfläche der Aderisoliprüng gewährleistet,
da ;sich verschiebende Binder öder Drähte nicht mehr verwendet werden. Auch läßt
sich ein gemäß der Erfindung ausgebildeter Schirm ohne großen Aufwand , mit einer
Erdungsklemme verbinden, da bereits durch Auffalten und Lochen des Schirmes an der
-Jinschlußstelle die Möglichkeit zum -unnittolbaren Anschließen der Ed sngsklemme
gegeben ist.
