Description
Technical field
The utility model relates to dragging makes field of cables, is specifically related to a kind of noise resistance and drags and make 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 a kind of noise resistance and drags and make cable, this noise resistance drags the dielectric constant making cable easily can reduce insulating barrier, and then reach and reduce electric capacity thus improve the transmission performance of cable, prevent cable cross-talk simultaneously, turn improve pliability, prevent frequent bending from causing external sheath layer to ftracture.
For achieving the above object, the technical solution adopted in the utility model is: a kind of noise resistance drags and 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 external sheath layer is coated on described high-modulus polyethylene fibres layer outer surface; All have in this external sheath layer containing several cavities.
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, if the volume in described individual cavity accounts for 30 ~ 40% of whole external sheath layer volume.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model noise resistance drags and 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, facilitate laying and the problem of emergency maintenance of cable, improve maintenance efficiency and repair quality, 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; Secondly, all have in external sheath layer containing several cavities, easily can reduce the dielectric constant of insulating barrier, and then reach and reduce electric capacity thus improve the transmission performance of cable, prevent cable cross-talk simultaneously, turn improve pliability, prevent frequent bending from causing external sheath layer to ftracture.
Accompanying drawing explanation
Accompanying drawing 1 makes construction of cable schematic diagram for the utility model noise resistance drags.
In above accompanying drawing: 1, heart yearn; 2, polyethylene strip; 3, copper conductor; 31, tin layers; 4, inner insulating layer; 5, polyester belt; 6, high-modulus polyethylene fibres layer; 61, polyethylene fibre; 7, external sheath layer; 8, cavity.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: a kind of noise resistance drags and 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, external sheath layer 7 and are coated on described high-modulus polyethylene fibres layer 6 outer surface; All have containing several cavities 8 in this external sheath layer 7.
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.
If the above-mentioned individual volume of empty 9 accounts for 30 ~ 40% of whole external sheath layer 7 volume.
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.
When adopting above-mentioned noise resistance to drag to make 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, facilitate laying and the problem of emergency maintenance of cable, improve maintenance efficiency and repair quality, 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; Secondly, all have in external sheath layer containing several cavities, easily can reduce the dielectric constant of insulating barrier, and then reach and reduce electric capacity thus improve the transmission performance of cable, prevent cable cross-talk simultaneously, turn improve pliability, prevent frequent bending from causing external sheath layer to ftracture.
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.
