Definitions
- the present invention relates to an electrical line with a metallic conductor enclosing sintered insulation from one or more Layers of an unsintered wrapping tape overlapping in the edge areas based on polytetrafluoroethylene.
- This wrapping tape has a plano-convex Cross-sectional shape, which is determined by a curved upper and a straight lower boundary line.
- Such an electrical line or cable is already out of the DE-PS 32 14 447 known.
- an unsintered one Wrapping tape for the production of insulation in the specified cross-sectional shape and the sintering of the polytetrafluoroethylene following the winding process the result is a compact, gap-free insulating sleeve with an extremely smooth exterior Surface that was previously only possible using an extrusion process.
- the known cable offers insulation a winding tape on its surface no points of attack for mechanical Forces that could tear open the insulation.
- the invention is therefore based on the object, the known cable or to strengthen known line so that it with the same compactness of the Insulation and closed smooth outer surface also meet the requirements after high mechanical strength and electrical dielectric strength is sufficient.
- polytetrafluor component in the embodiment of the invention crucial to the arc resistance and glow resistance of such cables and Lines at. All the more so as just to increase the electrical Tension and mechanical strength used according to the invention Polyimide wrapping tape meets the requirements regarding arc resistance and Resistance to smoldering is not sufficient.
- the wall thickness of the Overall insulation can be reduced, which leads to space and weight savings, a particular advantage of the line proposed according to the invention if as already mentioned, it is used for aircraft or satellite construction.
- Suitable fluoropolymers can be processed from the melt, such as, for example, the tetrafluoroethylene / hexafluoropropylene copolymer (FEP), the perfluoroalkoxy polymer (PFA), or also the tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (TFA / PFA), preference being given to the former.
- FEP tetrafluoroethylene / hexafluoropropylene copolymer
- PFA perfluoroalkoxy polymer
- TFA / PFA tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer
- PVDF polyvinylidene fluoride
- ETFE ethylene tetrafluoroethylene
- the materials mentioned can be on the top winding layer of the polyimide tape be extruded, but it is also possible to already have this fluoropolymer component to apply the wrapping tape itself, i.e. one with the fluoropolymer as an adhesive use laminated polyimide tape.
- Another advantageous variant is that which cannot be processed from the melt Fluoropolymers as a binder between the polyimide winding and the one To use polytetrafluoroethylene tape.
- polytetrafluoroethylene tape for example Polytetrafluoroethylene itself or one with a maximum of 2% by weight fluoromonomers modified polytetrafluoroethylene used in powder form.
- This polymer powder applied to the polyimide winding or onto the polyimide tape itself laminated form, melts at the sintering temperature for the winding tape Polytetrafluorethylene on and thus ensures a non-positive connection between the winding layers made of different polymer materials.
- the maximum thickness of the plano-convex wrapping tape i.e. the thickness in the reinforced middle region of the lenticular cross section, is advantageously between 15 to 100 ⁇ m, with a simultaneous thickness of the strip edge area of 5 ⁇ m and less, i.e. expiring towards 0.
- the advantageous width of the plano-convex winding tape is between 3 and 50 mm, preferably between 5 and 25 mm, depending on the conductor diameter.
- the invention is based on the embodiment shown in the figure explained in more detail.
- the metallic conductor 1 of the line according to the invention can be solid be, in the form shown it exists as a so-called stranded conductor for increasing the flexibility of the line from e.g. bare, tinned, silvered or nickel-plated copper wires or made of a copper alloy. Right away one or more layers of the polyimide tape are wound onto the stranded conductor 2.
- the intermediate layer 4 made of a fluoropolymer, for example a tetrafluoroethylene / hexafluoropropylene copolymer (FEP) or a first applied in powder form and then sintered Polytetrafluoroethylene (PTFE).
- FEP tetrafluoroethylene / hexafluoropropylene copolymer
- PTFE sintered Polytetrafluoroethylene
- the polyimide tape 2 is used to increase the dielectric strength of this Cable and its mechanical strength, while that from the PTFE tape 3 with the special cross-sectional shape existing single or multi-layer wrapping the high abrasion resistance, temperature resistance required for such cables and arc resistance guaranteed.
- Essential for the chosen wrapping is the overlap of the respective band edges, this is especially the Prerequisite for the closed, smooth outer surface of the from the Polytetrafluorethylene tape 3 formed envelope.
- Raised Belt edges as contact surfaces for external mechanical forces are avoided, Markings, even embossing on the surface, are also easy feasible without operating in the then prevailing conditions, such as aggressive media, moisture, dirt, etc., glow discharges and the Arcs are to be feared.
- a laminated polyimide tape is used in the practice of the invention, then this can also be coated on both sides to ensure a certain degree of adhesion to the Reaching ladder. This liability can make the stripping easier of the electrical conductor for the purpose of assembling the line.
