To achieve these goals, the utility model adopts following technical scheme: a kind of Aero-Space polytetrafluoroethylene film and the seamless lapped wire of tetrafluoro emulsion coating, comprise body, described body has strands conductor, per share stranded conductor forms by the thin silver-gilt copper wire of multiply is stranded, the outer seamless wrapped one deck of described stranded conductor or reverse wrapped two-layer polytetrafluoroethylene film, described polytetrafluoroethylene film applies tetrafluoro emulsion coating outward.
Further: described polytetrafluoroethylene film weaves one deck silver-gilt copper wire screen outward.
Further: to extrude one deck FEP protective layer outside described screen, or extrude layer of polyethylene protective layer, or seamless wrapped polytetrafluoroethylene film protective layer, described polytetrafluoroethylene film protective layer applies tetrafluoro emulsion coating outward.
Further: described FEP protective layer, or polyethylene protective layer, or the tetrafluoroethene thinfilm protective coating outer surface of outer surface tetrafluoro emulsion coating arranges along cable axis direction and anti-turn round colour band or anti-ly turn round recess.
Further: the described anti-cross section turning round recess is arcuation.
Compared with prior art, the utility model has following beneficial effect:
(1) resistance to bend(ing) is good: the silver-coated copper wire fine pith of conductor employing filament diameter 0.08mm is stranded to be formed, the resistance to bending of compact conformation; Insulating barrier adopts seamless wrapped polytetrafluoroethylene film to be coated with tetrafluoro emulsion coating outward, puts up frequent bending after being coated with tetrafluoro emulsion coating closely and also loosely can not occur gap, improve the resistance to bend(ing) of this product between film.
(2) humidity chemically-resistant is solvent impregnated: insulating material itself has the excellent solvent impregnated performance of humidity chemically-resistant, after insulating barrier applies four fluorine emulsion sintering outward, tetrafluoroethene thin dielectric film put up place sealing stronger, four fluorine emulsion true qualities of coating also have the excellent solvent impregnated performance of humidity chemically-resistant, make the solvent impregnated property of the humidity chemically-resistant of electric wire better.
(3) lightweight, external diameter is little: insulating barrier itself uses ultra-thin materials, and outer coating four fluorine emulsion occupies little space, with origin wire weight, the basic indifference of external diameter.
(4) insulation property strengthen: insulating material itself has excellent insulation resistance performance, and after insulating barrier applies four fluorine emulsion sintering outward, four fluorine emulsion true qualities of coating also have excellent insulation resistance performance, make the insulation resistance performance of electric wire better.
(5) cost-saving: insulating barrier applies tetrafluoro breast outward can carry out when electric wire sinters simultaneously, only needing a small amount of fee of material to increase all the other fringe costs such as labour cost, and scheme that the wrapped material of additional special enhances product performance need being increased than effectively having saved cost.
