The high strength light cable for the aerospace use is simple in structure and has the excellent performance, such as super high strength, high modulus, high temperature resistance, acid resistance, alkali resistance and light weight. The request for big bearing capacity, light weight and small volume can be fully satisfied.
Description
Technical field
The present invention relates to cable, particularly relate to a kind of Aero-Space high-strength light cable.
Background technology
Along with the develop rapidly of aerospace field, higher requirement be it is also proposed to the use of electric wire.Except meeting requirement on electric performance, also will meet lightweight, the instructions for use such as diameter is little, bearing capacity is large, high temperature resistant and resistance to wear is good, existing conventional products can not meet these requirements above.
Summary of the invention
In order to make up prior art problem, the object of this invention is to provide one and having rational in infrastructure, the Aero-Space high-strength light cable of lightweight, the performance such as bearing capacity is large, wear-resisting, radiation hardness.
In order to realize above-mentioned above-mentioned purpose, the invention provides following technical scheme:
A kind of Aero-Space high-strength light cable, comprise the cable core, separator, screen and the restrictive coating that are made up of many cores, described core ecto-entad is successively with insulating material with nickel plated copper conductor is wrapped forms, and the gap between described cable core and separator arranges strengthening core; Described screen is arranged on outside separator, and described restrictive coating is extruded in outside screen.
Described nickel plated copper conductor adopts the nickel plated copper conductor of concentric stranding, and twisting pitch ratio is not more than 16 times.Described insulating material adopts meta-position aramid fiber paper and polyester film compound to make.Described strengthening core is aramid fiber silk.Described separator is polyester film.Described screen adopts the braiding of nickel plating flat type copper wire to form.Restrictive coating adopts cross-linking radiation ETFE.
Beneficial effect of the present invention is:
Structure of the present invention is simple, and conductor adopts the nickel plated copper conductor of concentric stranding, can be used in Long-term service temperature and be no more than 260 DEG C and the higher occasion of mechanical strength.The composite material that insulating material adopts meta-position aramid fiber paper and polyester film to make, there is superhigh intensity, high-modulus and the premium properties such as high temperature resistant, acidproof, alkaline-resisting, lightweight, its intensity is 5-6 times of steel wire, modulus is 2-3 times of steel wire or glass fiber, its toughness is 2 times of steel wire, but its weight only has 1/5 of steel wire, at 560 DEG C of temperature, do not decompose, do not melt.Use aramid fiber silk as strengthening core, fully can meet the requirement that bearing capacity is large, lightweight, volume is little.The nickel plating flat type copper wire woven shield adopted, compared to the braiding of circle line, shield effectiveness increases, the more important thing is on the basis ensureing properties of product, reduce further the weight of product and decrease the volume of product.Restrictive coating adopts cross-linking radiation ETFE material, pass through irradiation, original linearity molecular structure is transformed into space network, improve the temperature resistant grade of product, meanwhile, this material proportion is only 1.73, there is excellent mechanical performance, wear-resisting resist bending, stress crack resistant, can not produce pollution, chemical stability is good, resistance to various space flight oil and liquid.
Accompanying drawing explanation
Fig. 1: structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 1: a kind of Aero-Space high-strength light cable, comprise the cable core, separator 4, screen 5 and the restrictive coating 6 that are made up of three cores 1, described core 1 ecto-entad is successively with insulating material 2 with nickel plated copper conductor 1 is wrapped forms, gap between described cable core and separator 4 arranges three strengthening cores 3, and described strengthening core 3 and core 1 interval are arranged; Described screen 5 is arranged on outside separator 4, and described restrictive coating 6 is extruded in outside screen 5.
Preferentially, described nickel plated copper conductor 1 adopts the nickel plated copper conductor 1 of concentric stranding, and twisting pitch ratio is not more than 16 times.Adopt the nickel plated copper conductor 1 of concentric stranding, Long-term service temperature can be used in and be no more than 260 DEG C and the higher occasion of mechanical strength.
Preferentially, described insulating material 2 adopts meta-position aramid fiber paper and polyester film compound to make.The composite material that insulating material 2 adopts meta-position aramid fiber paper and polyester film to make, there is superhigh intensity, high-modulus and the premium properties such as high temperature resistant, acidproof, alkaline-resisting, lightweight, its intensity is 5-6 times of steel wire, modulus is 2-3 times of steel wire or glass fiber, its toughness is 2 times of steel wire, but its weight only has 1/5 of steel wire, at 560 DEG C of temperature, do not decompose, do not melt.
Preferentially, described strengthening core 3 is aramid fiber silk.Use aramid fiber silk as strengthening core 3, fully can meet the requirement that bearing capacity is large, lightweight, volume is little.
Preferentially, described separator 4 is polyester film.
Preferentially, described screen 5 adopts nickel plating flat type copper wire to weave and forms.The nickel plating flat type copper wire woven shield 5 adopted, compared to the braiding of circle line, shield effectiveness increases, the more important thing is on the basis ensureing properties of product, reduce further the weight of product and decrease the volume of product.
Preferentially, restrictive coating 6 adopts cross-linking radiation ETFE.Restrictive coating 6 adopts cross-linking radiation ETFE material, pass through irradiation, original linearity molecular structure is transformed into space network, improve the temperature resistant grade of product, meanwhile, this material proportion is only 1.73, there is excellent mechanical performance, wear-resisting resist bending, stress crack resistant, can not produce pollution, chemical stability is good, resistance to various space flight oil and liquid.
