Abstract
The utility model relates to a wire rope composite cable for suspension, which comprises a wire rope with a twisted outer layer, wherein the inner core of the wire rope is provided with a coaxial cable core, the inner conductor of the cable core is a stranded conductor, the outer conductor thereof is wound by copper wire, an insulating layer is arranged between the inner conductor and the outer conductor, the outer layer of the outer conductor of the cable core is wrapped with an insulating layer, and a polyester strip is arranged between the insulating layer of the outer layer of the outer conductor of the cable core and the wire rope. The utility model has the advantages that 1) the inner conductor and the outer conductor of the cable adopt the coaxial structure, and the inner conductoris the stranded conductor, the outer conductor is wrapped in an inclined way, so the cable can meet the electrical performance and is flexible, 2) since the coaxial cable core is adopted, the strandedconductor is not filled with filling material, the structure of the cable is compact and the space is saved due to the small diameter, 3) before stranding the wire rope, the cable core adopts the polyester strip for winding as the strengthened element, so the direct friction of the wire rope to the cable core can be avoided when the cable is bent, 4) the design of the flexibility and roundness ofthe protective layer of the cable core ensures that the cable has high-strength and good repeated bending performance when in use.
Description
Technical field:
The utility model relates to a kind of cable, more specifically to a kind of suspention steel wire composite cable.
Background technology:
Along with the development of building industry, the situation of work high above the ground day by day increases in recent years, as: the external wall construction of skyscraper, decorative engineering not only need be hung hanging basket, also need be equipped with the required power supply of electric tool.Needs because of market, various types of steel wire composite cables have appearred, using more in the market is that a kind of twisted-pair feeder cable core is joined gasket for packing in parallel and made special cable at its outer steel wire rope that increases, its weak point is that the cable of operating state is reeled when the spool repeatedly with steel wire rope, because cable core material therefor hardness is inconsistent, when steel cable is stretched, cover wire rope meeting extruded cable core, twisted pair wire and the cable core that parallel gasket for packing is formed are subjected to that steel wire compressing back is normal to take place that twisted-pair feeder is squeezed and the situation that produces broken string, in addition because the coiling repeatedly of steel wire rope, twisted-pair feeder is different with the distortion of the different generations of material of gasket for packing, the elongation that this species diversity brings the damage of cable or cable each several part to produce is inconsistent, influence practical application, 4 these hawsers that for example are used for hanging basket cause hanging basket that crooked phenomenon takes place when extending inconsistent meeting.Suspending this workplace in midair needs good weatherability, pliability, mechanical strength height, good electric property, the consistent steel wire composite cable of elongation when cable is stressed.
The utility model content:
The purpose of this utility model be provide at the prior art weak point that a kind of pliability is good, mechanical strength is high, good electric property, not fragile, the consistent suspention steel wire composite cable of elongation when cable is stressed.
The purpose of this utility model is to realize by following measure: a kind of suspention steel wire composite cable, comprise outer stranded steel wire rope, it is characterized in that also having: described steel cable kernel is provided with the cable core of coaxial configuration, its inner wire is a strands, outer conductor is that copper wire twines, insulating barrier is arranged between inner and outer conductor, and described cable core outer conductor skin is enclosed with insulating barrier.
Between described cable core outer conductor outer insulation and the steel wire rope polyester belt is arranged.
Described cable core inner wire is 7 cores.
Described cable core inner wire is 19 cores.
Described outer conductor be the oblique looping of copper wire around.
Described outer conductor is the copper wire braiding.
Insulating barrier between described inner and outer conductor is a polyethylene.
Insulating barrier between described inner and outer conductor is fluoroplastics.
The outer wrap insulate layer of described cable core outer conductor is a polyethylene.
The outer wrap insulate layer of described cable core outer conductor is fluoroplastics.
Compared with prior art, owing to adopted the suspention steel wire composite cable that the utility model proposes, have the following advantages: 1) unimpeded for satisfying the galvanic circle, internal and external conductor adopts coaxial configuration, and inner wire is strands, and outer conductor be oblique bag composition, such structure is when satisfying electrical property, reach soft purpose, the particularly outer oblique packet mode that adopts can reduce the thickness of cable conduction layer, has vacateed the space for insulation thickens.2) owing to adopt coaxial cable core, there are not materials such as pair twist and filling, construction of cable compactness, diameter trifle save space; This design simultaneously has concentric symmetrical structure, each concentric antimere is same material, the material behavior unanimity, variation unanimity 3 when being subjected to external force) cable core adopts polyester belt to carry out wrapped before the stranded steel wire, wrapped back strand system wire element is simultaneously as reinforcing element, when cable is crooked, avoided the direct friction of steel wire, improved the mechanical strength of cable cable core.4) design of cable core sheath concentric type has guaranteed that cable in use has high strength and good repeated bending performance.5) high-strength material is adopted in insulation, and concentric design has improved the pressure measurement ability around cable core is anti-greatly.
Description of drawings:
Fig. 1 is the utility model example structure schematic diagram.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated: Fig. 1 is the utility model example structure schematic diagram.It comprises: outer stranded steel wire rope 1, described steel cable kernel is provided with the cable core 2 of coaxial configuration.Cable core adopts unique inside and outside coaxial configuration of leading when satisfying electrical property, also can be to better pliability.Described inner wire 21 is a strands, can be 7 cores, also can be 19 cores; Outer conductor 22 is that copper wire twines, can adopt oblique looping around, also can adopt braiding, tiltedly looping is around the extruding that can avoid self, better effects if.Insulating barrier 23 is arranged between inner and outer conductor, and insulating barrier can be nylon, also can adopt insulating material such as polyethylene, fluoroplastics.Described cable core outer conductor skin is enclosed with insulating barrier 24, and the material of insulating barrier is with aforementioned.Between described cable core outer conductor outer insulation and the steel wire rope polyester belt 25 is arranged, the effect of polyester belt is to avoid the direct friction of steel wire to cable core, has improved the mechanical strength of cable.
The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection range of the present utility model.
