Description
Technical field
The utility model relates to dragging makes field of cables, is specifically related to counter-bending the dragging of a kind of stretch-proof and makes cable.
Background technology
Common dragging makes its conductor of cable be single core copper conductor, it is the transfer wire adopting electrician's copper cash base to make through techniques such as drawing, annealing, the production process technology of this conductor is comparatively simple, and conductor is hardening due to factors such as oxidation, heatings in Long-Time Service process, become fragile.
The sheath of cable: common cable adopts one deck polyolefin jacket structure, this overcoat needs to obtain powerful electric power support and bulk information transmission in plant equipment running, need again the movement doing quick high frequency time with equipment and instrument, traditional telecommunication cable can only provide information transmission, fragile because of the bad mechanical strength of cable during fast moving together with equipment, thus affect cable to every electric property.
Because the said structure of cable limits to, lack certain ability preventing from affecting because of force-extension ability serviceability.
Summary of the invention
The utility model object is to provide counter-bending the dragging of a kind of stretch-proof and makes cable, this stretch-proof is counter-bending drags the flexibility making cable effectively raise outside cable, ensure the strain of cable tensionless winkler foundation, form the overcoat with desirable stretch-proof bending resistance, reduce the external diameter of cable greatly, facilitate laying and the problem of emergency maintenance of cable, improve maintenance efficiency and repair quality.
For achieving the above object, the technical solution adopted in the utility model is: counter-bending the dragging of a kind of stretch-proof makes cable, comprise: four heart yearns, this heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, one inner insulating layer is coated on described heart yearn outer surface, one polyester belt is wrapped in described four heart yearn outer surfaces, some polyethylene fibres are arranged at polyester belt outer surface abreast thus form high-modulus polyethylene fibres layer, and an oversheath insulating barrier is coated on described high-modulus polyethylene fibres layer outer surface.
In technique scheme, further improvement project is as follows:
1., in such scheme, described copper conductor diameter is 0.15 ~ 0.17 mm.
2., in such scheme, described polyethylene fibre diameter is 0.1 ~ 0.12 mm.
3., in such scheme, described copper conductor outer surface plating has tin layers.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
Counter-bending the dragging of the utility model stretch-proof makes cable, and its transmission characteristic can meet its transmission requirement, because cable have employed the stranded conductor of multiply tin-coated copper single line, effectively raises the flexibility of outside cable, simultaneously owing to arranging with adopting the PE fiber uniform parallel of high-modulus between cable core and outer jacket, and heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, ensure the strain of cable tensionless winkler foundation, form the overcoat with desirable stretch-proof bending resistance, reduce the external diameter of cable greatly, facilitate laying and the problem of emergency maintenance of cable, improve maintenance efficiency and repair quality, it is a kind of new product with development prospect, and mature production technology is stablized, the performance index of product meet products standards requirement, compared with traditional cable, stretch-proof bend-resistant electric cable had both had the strain of guarantee cable tensionless winkler foundation, guarantee that its transmission characteristic is steady in a long-term, have again lightweight, external diameter is little, pliability is good, the advantages such as price is low, there is obvious economic benefit and promotional value.
Accompanying drawing explanation
Accompanying drawing 1 makes construction of cable schematic diagram for counter-bending the dragging of the utility model stretch-proof.
In above accompanying drawing: 1, heart yearn; 2, polyethylene strip; 3, copper conductor; 4, inner insulating layer; 5, polyester belt; 6, high-modulus polyethylene fibres layer; 61, polyethylene fibre; 7, oversheath insulating barrier.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: counter-bending the dragging of a kind of stretch-proof makes cable, comprise: four heart yearns 1, this heart yearn 1 is made up of the polyethylene strip 2 and stranded 6 copper conductors 3 in polyethylene strip 2 outer surface being positioned at center, one inner insulating layer 4 is coated on described heart yearn 1 outer surface, one polyester belt 5 is wrapped in described four heart yearn 1 outer surfaces, some polyethylene fibres 61 are arranged at polyester belt 5 outer surface abreast thus form high-modulus polyethylene fibres layer 6, oversheath insulating barrier 7 and are coated on described high-modulus polyethylene fibres layer 6 outer surface.
Above-mentioned copper conductor 3 diameter is 0.15 ~ 0.17 mm, and above-mentioned polyethylene fibre 61 diameter is 0.1 ~ 0.12 mm.
Above-mentioned copper conductor 3 outer surface plating has tin layers.
Stranded conductor the key technical indexes: when 20 DEG C, D.C. resistance is≤93.8 Ω/km;
Conductor DC resistance 20 DEG C :≤93.8 Ω/km;
The mutual capacitance of cable :≤56 nF/km;
The insulation resistance of cable: >=10000 M Ω km.
Adopt that above-mentioned stretch-proof is counter-bending drags when making cable, its transmission characteristic can meet its transmission requirement, because cable have employed the stranded conductor of multiply tin-coated copper single line, effectively raises the flexibility of outside cable, simultaneously owing to arranging with adopting the PE fiber uniform parallel of high-modulus between cable core and outer jacket, and heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, ensure the strain of cable tensionless winkler foundation, form the overcoat with desirable stretch-proof bending resistance, reduce the external diameter of cable greatly, facilitate laying and the problem of emergency maintenance of cable, improve maintenance efficiency and repair quality, it is a kind of new product with development prospect, and mature production technology is stablized, the performance index of product meet products standards requirement, compared with traditional cable, stretch-proof bend-resistant electric cable had both had the strain of guarantee cable tensionless winkler foundation, guarantee that its transmission characteristic is steady in a long-term, have again lightweight, external diameter is little, pliability is good, the advantages such as price is low, there is obvious economic benefit and promotional value.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
