Abstract
This invention relates to a local communication cable including at least two section unit cable cores and an outer jacket, in which, said unit cable core is composed of at least a copper-clad aluminium pair wire and a surrounding aluminium molded compound ribbon, said unit core cables are added with a tinned copper wire wrapped by a single side Al molded compound ribbon with the Al ribbon facing inward, said unit cable cores include at least three sections filled with filling ropes among them to be wrapped with a protection polyester strap, which is wrapped with a total shild coppered Al molded compound and both of them are composite with the outer jacket, the coppered Al molded compound ribbon is formed by plating a pure copper layer on inside and outside surfaces of an Al base ribbon and then compositing a plastic film on the either side.
Description
Technical field
What the present invention relates to is a kind of telecommunication cable, especially a kind of follow-on city communication cable.
Background technology
Along with the laying of the new network of 3G, new requirement has been proposed the broadband city communication cable; Moreover, the electromagnetic wave power of various frequencies is increasing now, structure to local cable, cost, aspects such as antijamming capability have also proposed new requirement, therefore, though the Ministry of Information Industry had issued communication industry standard YD/T1281-2003 " being suitable for the copper core polyolefin insulating plastic-aluminum composite sheath city communication cable of broadband application " in 2003, wherein the formation and the technology of broadband city communication cable have been made regulation, but the at present this known city communication cable that includes at least two strands of unit cable cores in center and oversheath formation at least is good at satisfying the development need of present telecommunication cable technology, is subjected to certain restriction in actual applications.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of simple in structure, can reduce material consumption, reduce cost, improve shield effectiveness, the city communication cable that helps installing and using in the city.The objective of the invention is to finish by following technical solution, it includes at least two strands of unit cable cores in center and oversheath, and described unit cable core constitutes by the aluminium-plastic tape of copper cover aluminum twisted pair wire and periphery is compound mutually at least.
Also adding at least in the described unit cable core has a tinned copper wire, its peripheral individual layer wrapped the single face aluminium-plastic tape of aluminium strip in facing.
Described unit cable core has three strands at least, and is furnished with gasket for packing between the unit cable core, and the outside of unit cable core and gasket for packing is surrounded with the polyester belt that shields.
Described polyester belt outside also is compounded with the copper facing aluminium-plastic tape of total shielding usefulness, and polyester belt, copper facing aluminium-plastic tape and oversheath are combined with each other mutually.
After described copper facing aluminium-plastic tape plates one deck fine copper respectively by outside in the aluminium strip base, constitute at two-sided each compound one deck plastic film.
The invention belongs to a kind of improvement to prior art, it has simple in structure, can reduce material consumption, reduces cost, and improves characteristics such as shield effectiveness.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in the accompanying drawing 1, the center of having the present invention includes has two strands of unit cable cores 1 and oversheath 2 etc. at least, and described unit cable core 1 constitutes by copper cover aluminum twisted pair wire 11 and peripheral aluminium-plastic tape 12 are compound mutually at least.Also adding at least in the unit cable core 1 shown in Fig. 1 has a tinned copper wire 13, its peripheral individual layer wrapped the single face aluminium-plastic tape 12 of aluminium strip in facing.
Unit of the present invention cable core 1 has three strands at least, is four strands shown in the figure; Being furnished with gasket for packing 3 between unit cable core 1, is five shown in the figure.The outside of unit cable core 1 and gasket for packing 3 is surrounded with the polyester belt 4 that shields.And also be compounded with the copper facing aluminium-plastic tape 5 of total shielding usefulness in described polyester belt 4 outsides, and polyester belt 4, copper facing aluminium-plastic tape 5 are combined with each other mutually with oversheath 2.
After copper facing aluminium-plastic tape 5 of the present invention plates one deck fine copper respectively by outside in the aluminium strip base, constitute (not shown) at two-sided each compound one deck plastic film.
The kelvin effect characteristics that the present invention utilizes high-frequency signal with inexpensive copper clad aluminum material, have reduced cost in the city communication cable of high-frequency signal, its transmission performance satisfies the requirement of industry standard; The present invention adds in unit cable core 1 tinned copper wire 13, its peripheral individual layer wrapped the single face aluminium-plastic tape 12 of aluminium strip in facing, can improve shield effectiveness so on the one hand, can guarantee stablizing of cable core structure on the other hand again, also can make the outside diameter of cable as far as possible little, so that lay and install.For further improving shield effectiveness, the present invention has also selected the copper facing aluminium strip for use, and concrete example is: after the outside plates the fine copper of one deck 0.05mm respectively in the aluminium strip base of 0.15mm, at two-sided each compound one deck plastic film, its resistivity will drop to 0.0243 Ω .mm again
2/ m.
