Abstract
The utility model relates to an environment-friendly type low-attenuation RG11 coaxial cable comprising an inner conductor, a foamed insulation layer, an outer conductor and an outer sheath. The outer conductor includes a copper foil layer and a copper wire braiding shielding layer. And the inner conductor, the foamed insulation layer, the copper foil layer, the copper wire braiding shielding layer and the outer sheath are successively arranged along the radial direction from inside to outside. According to the coaxial cable, the copper foil is used for forming the outer conductor of the coaxial cable, thereby reducing the attenuation of the cable and improving the transmission performance of the cable; the outer conductor structure including the copper foil layer and the copper wire braiding shielding layer is employed, thereby substantially reducing the transfer impedance, improving the shielding attenuation index and realizing the excellent anti-interference performance; and the outer sheath uses the polyvinyl chloride or polyethylene sheath meeting the environment-friendly requirement of the European Union, thereby ensuring the whole environment-friendly performance of the coaxial cable.
Description
(1) technical field
The utility model relates to a kind of cable, the specifically low decay of a kind of environment-friendly type RG11 coaxial cable.
(2) background technology
For RG11 series coaxial cable, some national specification requirements of European Union and Unite States Standard are different, and following some deficiency is specifically arranged:
1,, owing to requiring transmission range longer, therefore, need the decay of coaxial cable lower.Traditional RG11 coaxial cable can not meet its application demand.
2, in addition,, because the size of interface accessory is different,, as the variation of inner wire diameter, bring the difficulty of coaxial cable foam process.
3, interference free performance requires higher.
4, traditional RG11 series coaxial cable is applicable to general occasion,, for EU Economy body country, must meet the environmental requirement of European Union fully.
(3) summary of the invention
The technical problems to be solved in the utility model is to provide the low decay of a kind of environment-friendly type RG11 coaxial cable, efficiently solves the difficult point of foam process, has improved the transmission performance of cable, and has guaranteed the environmental-protecting performance of cable.
For this reason, the utility model is taked following technical scheme:
The low decay of a kind of environment-friendly type RG11 coaxial cable, include inner wire, foaming insulation layer, outer conductor and oversheath, described outer conductor is comprised of copper foil layer and proof copper-wire braided screen, and described inner wire, foaming insulation layer, copper foil layer, proof copper-wire braided screen and oversheath radially arrange successively from inside to outside.
Described copper foil layer is close to the vertical bag of foamed insulation by the single-side copper-plastic composite insulating foil and is formed.
The utility model has the advantages that: 1, adopt the outer conductor of Copper Foil as coaxial cable, reduced the decay of cable, improved the transmission performance of cable; 2, adopt the outer conductor structure of copper foil layer and proof copper-wire braided screen, can the decrease transfger impedance, improve the shielding attenuation index, have good interference free performance; 3, oversheath adopts and meets polyvinyl chloride or the pe sheath that European Union environmental protection requires, and guarantees coaxial cable integral loop guaranteed cost.
(4) description of drawings
Fig. 1 is the utility model structure cross-sectional schematic;
Wherein, 1-inner wire, 2-foaming insulation layer, 3-copper foil layer, 4-proof copper-wire braided screen, 5-oversheath.
(5) specific embodiment
With reference to accompanying drawing 1, the low decay of environment-friendly type RG11 coaxial cable, include inner wire 1, foaming insulation layer 2, outer conductor and oversheath 5, described outer conductor is comprised of copper foil layer 3 and proof copper-wire braided screen 4, and described inner wire 1, foaming insulation layer 2, copper foil layer 3, proof copper-wire braided screen 4 and oversheath 5 radially arrange successively from inside to outside.Described inner wire 1 is the solid copper wire of diameter 1.70mm.Described foaming insulation layer 2 is to have high/low density polyethylene mixed foaming to form, and the proportioning of high/low density is 7:3.Described copper foil layer is close to the vertical bag of foamed insulation by the single-side copper-plastic composite insulating foil and is formed.The gross thickness of single-side copper-plastic composite insulating foil is 0.45mm, and wherein Copper Foil is not less than 18mm.The structure of described proof copper-wire braided screen is 7 * 16 * 0.127mm, and braided material is solid soft copper silk.Described oversheath is to meet the pe sheath that European Union environmental protection requires, and has good environmental-protecting performance, also has certain moisture-proof function.
Claims (2)
1. an environment-friendly type is hanged down decay RG11 coaxial cable, include inner wire, foaming insulation layer, outer conductor and oversheath, it is characterized in that: described outer conductor is comprised of copper foil layer and proof copper-wire braided screen, and described inner wire, foaming insulation layer, copper foil layer, proof copper-wire braided screen and oversheath radially arrange successively from inside to outside.
