Abstract

The netting wire is for security fences, and includes a security wire (1) which lies in the middle of the construction and is surrounded by an insulating cover (2). Pref. two security wires (1) are used and can conduct electricity without short-circuiting under normal conditions. To reinforce this core construction a number of support wires (3) can be arranged cylindrically about it. The support wires (3) are pref. spirally wound. The complete construction can be protected by an insulating sheat (4) completely surrounding the outer circumference. Both the security (1) and supporting (3) wires can be functional in the electrical monitoring.

Description

BESCHREIBUNGDESCRIPTION

Geflechtdraht für Sicherheitszäune.Braided wire for security fences.

Die Basis für die Herstellung eines Zaungeflechtes für Sicherheitszäune ist ein Draht, der in seinem Aufbau Trägerdraht, Sicherungsdraht und Isoliermantel als Minimum aufweist. Dass hierbei der Sicherungedraht - vorzugsweise ein Widerstandsdraht mit großer Temperaturstabilität - in dem Aufbau so angebracht ist, dass er mechanisch schwer freizulegen ist, ist ein wichtiger Faktor für die Sicherheit gegen eine elektrische Überbrückung. In dem bekannten System wurde dies dadurch erreicht, dass der Sicherungsdraht in einer Nut des Trägerdrahtes verankert war.The basis for the production of a fence mesh for security fences is a wire, which in its structure is carrier wire, fuse wire and insulating sheath has as a minimum. That this is the safety wire - preferably a resistance wire with great temperature stability - in the structure is attached so that it is mechanical Difficult to expose is an important factor in security against an electrical Bridging. In the known system this was achieved in that the safety wire was anchored in a groove in the carrier wire.

Der Gegenstand der Anmeldung erreicht diese Sicherheit dadurch, dass der Sicherungsdraht in die Mitte des Aufbaues verlegt wird. Die Funktion des Trägerdrahtes wird durch eine Anzahl rund um den Kern angeordneter Trägerdrähte, die vorzugsweise in der Länge spiralförmig um den Kern verseilt sind, erreicht. Der für den Gegenstand der Anmeldung spezielle Aufbau ist wie folgt vorgenommen.The subject of the application achieves this security in that the safety wire is laid in the middle of the structure. The function of the carrier wire is supported by a number of carrier wires arranged around the core, which are preferably are twisted in length spirally around the core. The one for the subject The registration special structure is made as follows.

Vorzugsweise zwei Sicherungsdrähte 1 stellen mit einem Isoliermantel 2 den Kern dar. Selbstverständlich sind die beiden Sicherungsdrähte 1 hierbei in ausreichendem elkrtischen Sicherheitsabstand angeordnet. Um diesen Kern sind vorzugsweise eine gemäß dem Umfang festgelegte Anzahl von Trägerdrähten 3 spiral- oder geflechtsförmig angeordnet. F.rforderlichenfalls können diese Trägerdrähte durch geeignete Bindemittel unlösbar miteinander verbunden werden. Über diesen Trägerdrähten 3 ist ein isolieredder Aussenmantel 4 aufgebracht. Zum Zweck der Überwachung sind beide Sicherungsdrähte 1 und die Trägerdrähte 3 in die elektrische Überwachung einbezogen.Preferably two fuse wires 1 provide with an insulating jacket 2 represents the core. Of course, the two safety wires 1 are shown in FIG arranged at a sufficient electrical safety distance. Around this core are preferred a number of carrier wires 3 determined according to the circumference in a spiral or braid shape arranged. If necessary, these carrier wires can be fixed by means of suitable binders are inextricably linked. Over these carrier wires 3 is an insulating edder Outer jacket 4 applied. For monitoring purposes, both are fuse wires 1 and the carrier wires 3 included in the electrical monitoring.
