Wherein, more tensile core annular spreads are in the outside of conductor wire core group.
Further, the cable core conductor is that more tinned copper wires are twisted.
Further, the insulating layer is ethylene-propylene rubber layer.
Further, the filled layer is to be filled between compound cable core and water blocking layer using water blocking yarn.
Further, the water blocking layer is to form using waterstop is wrapped.
Further, the inner restrictive coating and external sheath layer are TPU layer.
Further, the armor is to be woven using stainless steel wire.
Compared with prior art, the utility model has the beneficial effects that
1, cable is internally provided with tensile core, which is made by twisting using stainless steel wire, tensile strength and surrender
Intensity is much higher than conductor wire core, and when external force pulls cable, drag force is all acted in tensile core, to avoid leading
Wire core is pulled and is broken.
2, it is additionally provided with filled layer and water blocking layer in the outside of compound cable core, the compound cable core of filled layer dense packing effect works as water
When dividing from the end of cable or flowing into from cable meter layer indentation, there, filled layer and water blocking layer can meet water and expand prevention moisture edge rapidly
The longitudinal further diffusion of cable, realizes the purpose of longitudinal waterproof of cable.The conductor wire core of the compound cable core is provided with use
Waterproof layer is sealed made of sealant, when moisture is flowed into from cable meter layer indentation, there, can prevent moisture from passing through sealing waterproof layer
It impregnates cable core conductor and electric leakage accident occurs, realize the purpose of the radial waterproof of compound cable core.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is a kind of structural schematic diagram of tension water-proof cable of the utility model；
In figure: 1- conductor wire core；11- cable core conductor；12- seals waterproof layer；13- insulating layer；2- tensile core；3- filling
Layer；4- water blocking layer；5- inner restrictive coating；6- armor；7- external sheath layer.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figure 1, a kind of tension water-proof cable described in the utility model, compound including what is set gradually from the inside to the outside
Cable core, filled layer 3, water blocking layer 4, inner restrictive coating 5, armor 6, external sheath layer 7.
Specifically, the compound cable core includes conductor wire core 1 and tensile core 2, the preferred conductor wire core 1 of the present embodiment and tension
The quantity of core 2 is respectively three, and three conductor wire cores 1 twist together to form 1 group of conductor wire core, three 2 annular spreads of tensile core
In 1 group of outside of conductor wire core.
The tensile core 2 is to be twisted using stainless steel wire, and the tensile strength and yield strength of stainless steel wire are much higher than
Conductor wire core 1, when external force pulls cable, drag force is all acted in tensile core 2, to avoid conductor wire core
It is pulled and is broken, make cable that there is very strong tensile property.
Further, the conductor wire core 1 is used for transmission electric power, is successively enclosed with cable core conductor 11, close from the inside to the outside
Seal waterproof layer 12, insulating layer 13.The cable core conductor 11 is that more tinned copper wires are twisted, and the biography of electric current is carried out using copper wire
Defeated, load ratio aluminium wire iron wire is big, and conductive capability is strong, can reduce loss of the electric current on conducting wire, prevents copper wire surface layer is tin plating
The only aerial oxidation of copper wire.The sealing waterproof layer 12 gives as security the table for overlaying on cable core conductor 11 using sealant by extruding machine
Layer, the sealant is by maleate, acrylate and Vinyl Acetate Copolymer Emulsion as main emulsion, in main emulsion
The copolymer that the raw materials such as aqueous tackifier lotion, VAE lotion, wax emulsion mix is added, meets country and European Union environmental protection mark
It is quasi-.The sealant is the sealing material with certain caking property, and the gap between twisted copper wire can be filled to form a cause
Close sealant plays the role of sealing, stops moisture radial inflow to conductor wire core 1.The insulating layer 13 is using second third
Rubber is made, and with good electrical insulation capability, high fillibility and water resistance, conductor wire core 1 can be made to have strong insulating properties
And water resistance.Preferably, the insulating layer 13 and sealing waterproof layer 12 use the technology of double-layer coextrusion to be wrapped in cable core conductor 11
Surface layer so that insulating layer 13 and sealing 12 close adhesion of waterproof layer gap may be not present, further prevent moisture from cable
Longitudinal, radial inflow realizes the two-way water-resistant performance to cable core conductor 11.
Further, the filled layer 3 is to be filled between compound cable core and water blocking layer 4 using water blocking yarn, described to block water
Layer 4 is to form using waterstop is wrapped.The filled layer 3 and water blocking layer 4 are densely wrapped in the outside of compound cable core, and hinder
Water yarn and waterstop can expand rapidly after meeting water, and the gap between the compound cable core of dense packing effect prevents moisture along compound cable core
Longitudinal diffusion between gap, to realize the purpose of longitudinal waterproof of cable.
The inner restrictive coating 5 and external sheath layer 7 are TPU layer.The TPU layer has the characteristics that wear-resisting, oil resistant, with high hardness,
Make cable wearability with higher, the friction that can prevent cable from generating in use and destroy cable interior waterproof layer, block water
Layer 4 and compound cable core, realize the electrical isolation and wear-resistant protection of cable.The armor 6 is to be woven using stainless steel wire,
It is preferred that count reaches 85% or more, makes cable inside compression strength with higher and endurance life, outside can be kept out
The shape invariance of cable is kept to the pressure of cable, furthermore reticular structure is made in braiding layer, can reduce the total weight of cable, side
Just it installs.
