Description

A kind of resistance to irradiation double-deck color separation X-ETFE insulation aviation space flight cable
Technical field
The utility model belongs to cable technical field of cables, relates to a kind of resistance to irradiation double-deck color separation X-ETFE insulation aviation space flight cable.
Background technology
In recent years, along with the develop rapidly of Aeronautics and Astronautics industry, no matter be civil aircraft or military aircraft, it controls, transmission system is day by day complicated.Simultaneously, the aggregate demand playing the Aero-Space cable of electric power transfer and information transmission in aircraft constantly increases, usual cable total length can reach several hundred kilometers, and the increase of Aero-Space cable weight is day by day serious on the impact of take-off weight, and Aero-Space electric wire environment for use is severe.So also more and more higher to the requirement of Aero-Space cable performance, it need possess, and core can be distinguished, lightweight, resistance to irradiation, the feature that high temperature resistant, reliability is high, but existing cable can not meet above-mentioned requirements.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, and provide a kind of resistance to irradiation double-deck color separation X-ETFE insulation aviation space flight cable, the core of this cable can be distinguished, and has radiation hardness, the characteristic that lightweight, high temperature resistant and reliability is high.
For achieving the above object, resistance to irradiation described in the utility model double-deck color separation X-ETFE insulation aviation space flight cable comprises cable core and is wrapped in the outer jacket outside cable core, described cable core forms by least two insulated single wires are stranded, and twisting pitch is 6 ~ 8 times of lay ratios, described insulated single wire comprises copper stranded conductor and the inner insulating layer be located at from inside to outside outside copper stranded conductor and external insulation layer, outer jacket comprises circular copper wire braid and restrictive coating from inside to outside successively, and the color of inner insulating layer outer surface is different from the color of external insulation layer outer surface.
Described circular copper wire braid is woven by some circular copper wires and forms, and the surface of the surface of circular copper wire and copper stranded conductor is all silver-plated.
Described copper stranded conductor is made up of some strands of twisted wires, and each stock twisted wire is left-hand concentric type bundle strand and forms.
The external diameter of each twisted wire is less than or equal to 0.74mm.
The thickness of described inner insulating layer is 0.08mm-0.12mm;
The thickness of described external insulation layer is 0.1mm-0.15mm.
The diameter of described circular copper wire is 0.1mm, and the density of each circular copper wire braiding is more than or equal to 98%.
The utility model has following beneficial effect:
Resistance to irradiation described in the utility model double-deck color separation X-ETFE insulation aviation space flight cable comprises cable core and outer jacket, cable core forms by some insulated single wires are stranded, described insulated single wire is provided with copper stranded conductor, inner insulating layer and external insulation layer from inside to outside successively, wherein the color of inner insulating layer outer surface is different from the color of external insulation layer outer surface, thus realize the differentiation of dual-layer color, simultaneously be provided with circular copper wire braid in outer jacket, thus make described resistance to irradiation double-deck color separation X-ETFE insulation aviation space flight cable have radiation hardness, the characteristic that high temperature resistant and reliability is high.In addition, each cable core forms by least two insulated single wires are stranded, and twisting pitch is 6 ~ 8 times of lay ratios, lightweight, meets the demand of current Aeronautics and Astronautics industrial development.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 be insulated single wire, 2 be circular copper wire braid, 3 be restrictive coating, 11 be copper stranded conductor, 12 be inner insulating layer, 13 for external insulation layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 1, resistance to irradiation described in the utility model double-deck color separation X-ETFE insulation aviation space flight cable comprises cable core and is wrapped in the outer jacket outside cable core, described cable core forms by least two insulated single wires 1 are stranded, and twisting pitch is 6 ~ 8 times of lay ratios, described insulated single wire 1 comprises copper stranded conductor 11 and the inner insulating layer 12 be located at from inside to outside outside copper stranded conductor 11 and external insulation layer 13, outer jacket comprises circular copper wire braid 2 and restrictive coating 3 from inside to outside successively, and the color of inner insulating layer 12 outer surface is different from the color of external insulation layer 13 outer surface.
It should be noted that, described circular copper wire braid 2 is woven by some circular copper wires and forms, and the surface of the surface of circular copper wire and copper stranded conductor 11 is all silver-plated, and copper stranded conductor 11 is made up of some strands of twisted wires, and each stock twisted wire is left-hand concentric type bundle strand and forms.The external diameter of each twisted wire is less than or equal to 0.74mm, the thickness of inner insulating layer 12 is 0.08mm-0.12mm, the thickness of external insulation layer 13 is 0.1mm-0.15mm, the diameter of circular copper wire is 0.1mm, the density of each circular copper wire braiding is more than or equal to 98%, not bonding mutually between inner insulating layer 12 with external insulation layer 13, inner insulating layer 12 and external insulation layer 13 all adopt X-ETFE Insulation Material to be made.
Above embodiment only for illustration of the utility model, but not for limiting the utility model.
