Zweiadrige, mantellose Leitung für FemmeldezweckeTwo-core, sheathless cable for telecommunication purposes
Für mobile Einsatzzwecke in der Fernmeldetechnik werden mitunter flexible, mantellose Leitungen verwendet, die aus zwei miteinander verseilten Adern bestehen. Bei derartigen Leitungen müssen die Adern selbst hinreichend zugfest und ihre Isolierung gegenüber Umwelteinflüssen hinreicnend widerstandsfähig sein. Bei einer gebräuchlichen Leitung dieser Art besteht jede Ader aus einem Litzenleiter aus Stahl- und Kupferdrähten und einer zweischichtigen Isolierung aus Polyäthylen und Polyamid. For mobile applications in telecommunications technology, flexible cables without a jacket are sometimes used, the consist of two cores stranded together. With such lines, the wires themselves must be sufficient tensile strength and their insulation sufficiently resistant to environmental influences. With a common Each wire consists of a stranded conductor made of steel and copper wires and a wire of this type two-layer insulation made of polyethylene and polyamide.
Zur zugfesten Ausgestaltung der Adern einer elektrischen Leitung mit Kunststoffmantel ist es weiterhin bekannt, im Kern jeder Ader ein zugfestes Tragorgan aus beispielsweise Baumwoll- oder Nylonfäden oder aus Glasfasern anzuordnen, hierauf die Leiterdrähte aufzuspinnen und auf den Leiter zunächst eine Schutzhülle und dann eine zweischichtige Isolierhülle aufzubringen (US-PS 29 00 437). Für eine schwere bewegliche Gummi"For the tensile design of the cores of an electrical line with a plastic sheath, it is also known in the core of each wire a tensile load-bearing element made of, for example, cotton or nylon threads or glass fibers to arrange, then spin the conductor wires and first a protective cover and on the conductor then apply a two-layer insulating cover (US-PS 29 00 437).

schlauchleitung ist weiterhin ein im Zentrum der Leitung angeordneter Erdleiter bekannt, der aus einem Tragorgan aus Nylonfäden, den darauf aufgebrachten Leiterdrähten und einer Isolierung aus Polypropylen besteht (US-PS 36 99 238).hose line is also known an earth conductor arranged in the center of the line, which consists of a support member consists of nylon threads, the conductor wires attached to them and an insulation made of polypropylene (U.S. Patent 3,699,238).
Der Neuerung liegt die Aufgabe zugrunde, der eingangs erwähnten Fernmeldeleitung für mobile Einsatzzwecke durch konstruktive Neugestaltung einen zusätzlichen An-Wendungsbereich zu schaffen, insbesondere das Gewicht zu verringern, die mechanischen Eigenschaften und die Widerstandsfähigkeit gegen Umwelteinflüsse zu verbessern. The innovation is based on the task mentioned at the beginning mentioned telecommunication line for mobile use by constructive redesign an additional application area to create, in particular, to reduce the weight, the mechanical properties and the To improve resistance to environmental influences.
Zur Lösung dieser Aufgabe ist gemäß der Neuerung vorgesehen, daß jede Ader der zweiadrigen, flexiblen und mantellosen Leitung aus einem Tragorgan aus hochfesten Kunststoffäden, aus einem auf das Tragorgan ein- oder mehrlagig aufgesponnenen Leiter aus Kupfer- oder Aluminiumdrähten und aus einer den Leiter umgebenden hochtemperaturbeständigen Isolierung aus einem fluorierten Kunststoff besteht, insbesondere aus einem Copolymer aus Äthylen und Tetrafluoräthylen (ETFE, Handelsname "Tefzel") oder einem Copolymer aus Äthylen und Chlortrifluoräthylen (ECTFE, Handelsname "Halar").To solve this problem it is provided according to the innovation that each wire of the two-wire, flexible and Sheathless line from a support element made of high-strength plastic threads, from a one on the support element or multilayer spun-on conductors made of copper or aluminum wires and from a high-temperature-resistant insulation made of a fluorinated material surrounding the conductor Plastic consists, in particular, of a copolymer of ethylene and tetrafluoroethylene (ETFE, trade name "Tefzel") or a copolymer of ethylene and chlorotrifluoroethylene (ECTFE, trade name "Halar").
Eine derart ausgebildete Fernmeldeleitung zeichnet sich vor allem durch hohe Zugfestigkeit, verbesserte Abriebbeständigkeit, hohe Temperaturbeständigkeit bis zu 150 0C, verbesserte Beständigkeit gegenüber Chemikalien und durch Schwerentflammbarkeit und selbstverlöschende Eigenschaft aus. Die neue Leitung, deren Tragorgane beispielsweise aus Fäden, Kordeln oder Garnen bestehen können, ist daher besonders geeignet zum Einsatz im Bereich technischer Hilfsdienste, der Bergwacht, beiA thus formed transmission line is distinguished in particular by high tensile strength, improved abrasion resistance, high temperature resistance up to 150 0 C, improved chemical resistance and flame retardancy and self-extinguishing property of. The new line, the supporting elements of which can consist of threads, cords or yarn, for example, is therefore particularly suitable for use in the field of technical auxiliary services, the mountain rescue service

Die beiden Adern der neuen Leitung können, wie bisher üblich, miteinander verseilt sein. Es besteht aber auch die Möglichkeit, die Adern in Form einer Zwillingsleitunfe parallel zueinander anzuordnen, indem die Isolierhüllen der Adern gleichzeitig in einem Spritzkopf gespritzt und seitlich miteinander verbunden werden.The two wires of the new line can be stranded with one another, as was previously the case. But there is also the possibility of arranging the wires parallel to one another in the form of a twin wire , by simultaneously injecting the insulating sleeves of the wires in an injection head and connecting them to one another at the sides.
Für die im Rahmen der Neuerung vorgesehenen Tragorgane eignen sich insbesondere Kunststoffe, die unter dem Handelsnamen "Kevlar" vertrieben werden und bei denen es sich um aromatische Polyamide handelt. Bei dem Tragorgan, das aus vielen Einzelfäden besteht, kann es sich um eine verseilte, geflochtene oder gesponnene Kordel oder auch um einen gezwirnten Faden handeln. Das Tragorgan kann gegebenenfalls besonders behandelt, bei- I spielsweise imprägniert sein. " IFor the support members provided as part of the innovation, plastics are particularly suitable that are under the Trade names "Kevlar" are marketed and where they are aromatic polyamides. In the case of the supporting element, which consists of many individual threads, it can be a stranded, braided or spun cord or a twisted thread. The supporting organ can optionally be specially treated, for example impregnated. "I.
