But aerial cable is due to working under hard conditions, easily by environmental condition (such as ice, wind, rain, snow, temperature, chemical attack, thunder and lightning etc.)
Influence, especially in a humid environment, grieshoch steam that long-term use can be put aside etc. corrodes the jacket layer of cable.And present city
Existing common aerial cable easily occurs disconnected under conditions of bad weather in the case where external gravity or pulling force is born on face
, there is serious accident in the phenomenon split.
The content of the invention
The purpose of this utility model is to provide a kind of reinforced aerial cable of the steel core of function admirable.
For achieving the above object, the technical scheme that the utility model is used is：A kind of reinforced built on stilts electricity of steel core
Cable, including conductor, sheath and annular hornblock, the conductor include that many are strengthened aluminium Baogang core twisted wire layer and many aluminum stranded conductor layers,
The many aluminum stranded conductors layer is coated on many and strengthens aluminium Baogang core twisted wire layer outside；The sheath is followed successively by shielding from inside to outside
Layer, insulating barrier, waterproof layer, anticorrosive coat and belting layer, the insulating barrier use IXPE material, the anticorrosive coat by
Tin-coated copper wire netting and the corrosion-resistant epoxy paint composition being coated with thereon；The annular hornblock is to be looped around two angles on the outside of sheath
Block, described two hornblocks are symmetrical along the RADIAL of sheath.
Preferably：Described waterproof layer is polyurethane waterproof coating.
Preferably：Described annular hornblock uses light plastic.
Preferably：The hornblock angle of described annular hornblock is 60 °.
The utility model has the advantages that：The utility model has excellent tensile property and electric conductivity, and
Shield effectiveness is good, and external interference resistance is strong, being capable of waterproof, anti-corrosion and anti-accumulated snow.Specifically, the utility model is by using
Many are strengthened aluminium Baogang core twisted wire, enhance the tensile property of cable, and it is more to strengthen aluminium Baogang core twisted wire layer outer cladding at many
Root aluminum stranded conductor, enhances the electric conductivity of cable.Anticorrosive coat in sheath is prevented by tin-coated copper wire netting and the epoxy being coated with thereon
Rotten coating composition, tin-coated copper wire netting also has shielding action, can strengthen the shield effectiveness of cable, and the epoxy being coated with thereon is prevented
Rotten coating wearability is good, adhesive force strong, also with good water resistance, further enhancing the water resistance of cable.Additionally, setting
Put annular hornblock on the outside of sheath can effectively anti-accumulated snow, the accumulated snow weight differential on two hornblocks can make cable natural rotation,
And then slide accumulated snow.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model another embodiment.
Specific embodiment
The reinforced aerial cable of a kind of steel core as shown in Figure 1, including conductor, sheath and annular hornblock 8, the conductor bag
Include many and strengthen aluminium Baogang core twisted wire 1 and Duo Gen of layer aluminum stranded conductors layer 2, many aluminum stranded conductors layer 2 is coated on many reinforcement aluminium bags
The outside of steel core twisted wire layer 1.Strengthen the tensile property that aluminium Baogang core twisted wire layer 1 enhances cable, its outer cladding by setting many
Many aluminum stranded conductors layer 2, enhance the electric conductivity of cable, make cable in the case where external gravity or pulling force is born, also not
The phenomenon of fracture occurs.
In order to reduce influence and damage of the natural environment to cable, sheath is set into multilayer with reinforced sheath to conductor
Protective effect, the sheath is followed successively by screen layer 3, insulating barrier 4, waterproof layer 5, anticorrosive coat 6 and belting layer 7 from inside to outside.It is described
Insulating barrier 4 uses IXPE material, insulating barrier 4 is had excellent anti-flammability, high-fire resistance and outstanding physics
Mechanicalness, cross-linking radiation reaction can improve polymer into charcoal, and then improve its anti-flammability, also improve the utility model
Fireproof grade.
In the more area of rainfall, strengthen the water resistance of cable, it is also very must to reduce erosion of the rainwater to cable
Want.Therefore, waterproof layer 5 is additionally provided with the sheath of cable, the waterproof action of the waterproof layer 5 can be real in several ways
It is existing.For example, the waterproof layer 5 can be several layers scribbling the carbon fiber of waterproof membrane, carbon fiber density is low, intensity is high, high temperature resistant and
Corrosion resistance is small, and thermal coefficient of expansion is small and with anisotropy, can strengthen the protective action to conductor, but carbon fiber cost phase
To higher, the cost of cable can be increased.Or waterproof layer 5 can be the epoxy resin layer for being coated in the outside of insulating barrier 4, equally may be used
To play waterproofing protection effect.It is preferred that described waterproof layer 5 is polyurethane waterproof coating, the smearing is soft to be easy to apply again
Work, cohesive force is strong, can renitency infiltration, have on the basis of excessively cable cost is not increased cable anti-well
Water is acted on, and is not influenceed by rainwater weather.
Anticorrosive coat 6 is additionally provided with the outside of waterproof layer 5, the anticorrosive coat 6 is by tin-coated copper wire netting and the ring being coated with thereon
Oxygen anticorrosive paint is constituted.Wherein, tin-coated copper wire netting also has shielding action, can strengthen the shield effectiveness of cable, applies thereon
The corrosion-resistant epoxy paint wearability of cloth is good, adhesive force is strong, also with good water resistance, further enhancing the water proofing property of cable
Energy.
Additionally, being additionally provided with annular hornblock 8 on the outside of sheath, the annular hornblock 8 is to be looped around two on the outside of sheath
Hornblock, described two hornblocks are symmetrical along the RADIAL of sheath.As shown in figure 1, the annular gusset 8 by two blocks of identical gussets and
The arc-shaped side at gusset edge is spliced, and two hornblocks are symmetrical along the RADIAL of sheath, i.e., the top line of two blocks gussets crosses shield
The center of set.So once load-bearing difference occurs and will make cable natural rotation on two blocks of gussets, make the object on gusset quick
Slide, prevent from piling up.Or as shown in Fig. 2 annular hornblock 8 can be spliced by two relative isosceles triangles in base,
There is the recess matched with sheath outside on the base of shown triangle, and described matching refers to two base recesses of triangle
The shape for piecing together is consistent with sheath outside, i.e., just seamlessly be wrapped in sheath interior by annular gusset 8.
Annular hornblock 8 can make cable possess anti-accumulated snow effect, in sleety weather, when sleet is dropped on cable,
Two hornblocks of annular hornblock 8 make cable rotate naturally because of unbalance stress, and the rainwater and accumulated snow on cable are with the rotation of cable
Accelerate to slide, can effectively reduce influence of the sleety weather to cable.Further to optimize the construction of cable, described annular hornblock 8
Using light plastic, weightening of the structure of annular hornblock 8 to cable is which reduced.The hornblock angle of described annular hornblock 8 can
To be the arbitrary value in the range of 15 °~105 °, preferably 60 °, so can make the fast ski-running of rainwater and accumulated snow on cable
Fall, reach more preferable anti-accumulated snow effect.
