Bahnförmiges IsoliermaterialSheet-like insulating material

Die vorliegende Erfindung betrifft ein flächenhaftes bahnförmiges Laminat, insbesondere in Streifenform, zur Herstellung wärmeisolierter Mehrader-Kabel, zB. Schichtenmantelkabel. Es sind Mehrader-Kabel bekannt, die eine Wärmeisolation dadurch erhalten, daß man sie mit einer Lage bandförmiger Polyäthylenterephthalatfolxe umspinnt, darüber zwei weitere Lagen aus streifenförmiger Polyäthylenfolie anbringt und diese Schicht durch eine weitere gewickelte Lage aus bandförmiger Polyäthylenterephthalatfolie abdeckt. Die bekannte Wärmeisolation hat den Nachteil, daßThe present invention relates to a flat sheet-like laminate, in particular in strip form, for Manufacture of heat-insulated multi-core cables, e.g. Layered sheathed cable. There are multi-core cables known that receive thermal insulation by having them with a Layer of ribbon-shaped polyethylene terephthalate foil wrapped around it, over that two further layers of strip-shaped polyethylene film attaches and this layer through a further wound layer of tape-shaped polyethylene terephthalate film covers. The known thermal insulation has the disadvantage that

die Wärme, bedingt durch die hohe Spritztemperatur beim Aufbringen des Außenmantels aus thermoplastischem Kunststoff, wie beispielsweise Polyvinylchlorid oder Polyäthylen im Extrudierverfahren, nicht in der gewünschten Form durch die bisher mehrlagig aufgebrachten Folienisolationsschichten abgebaut wurde, d.h. es traten bisher beim Außenmantelspritzen Fehler im Kabelinneren derart auf, daß die einzelnen Aderisolationen aufgrund der hohen Außenmantelspritztemperaturen weich wurden und miteinander verklebten, bzw. mit der untersten Isolationsfolienschicht verklebten. Dies wird, wie umfangreiche Versuche mit diesem Laminat zeigten, mit dem neuen zwei- bzw. dreischichtigen Laminat vermieden. Außerdem können die Rüstzeiten und damit die Kabelerstellungskosten gesenkt werden9 da anstelle der bisher vier und mehr Isolationslagen künftig nur noch zwei, höchstens drei Isolationslagen zur Wärmeisolierung nötig sind«the heat, due to the high injection temperature when applying the outer sheath made of thermoplastic material, such as polyvinyl chloride or polyethylene in the extrusion process, was not dissipated in the desired form by the previously multilayered film insulation layers, i.e. errors in the interior of the cable have so far occurred during outer sheath injection, that the individual core insulation became soft due to the high outer jacket injection temperatures and stuck together or stuck to the bottom layer of insulation film. As extensive tests with this laminate have shown, this is avoided with the new two- or three-layer laminate. In addition, the set-up times and thus the cable production costs can be reduced 9 because instead of the previous four or more layers of insulation, only two or a maximum of three layers of insulation are required for thermal insulation in the future «

Der Erfindung liegt die Aufgabe zugrunde, eine flächenhafte bahnförmige Werkstoffkombination vorzuschlagen, mit deren Hilfe es möglich ist, wärmeisolierte Mehrader-Kabel herzustellen, die Nachteile bekannter wärmeisolierter Kabel der genannten Gattung nicht aufweisen und dem isolierten Kabel Schutz gegen Beschädigung durch Knickbeanspruchung gewähren»The invention is based on the object of proposing a two-dimensional, web-like material combination with which Help it is possible to manufacture thermally insulated multi-core cables, do not have the disadvantages of known thermally insulated cables of the type mentioned and the insulated cable Provide protection against damage from buckling loads »
