Abstract
The utility model discloses a copper clad aluminum communication cable, and relates to a signal transmission device. The copper clad aluminum communication cable comprises a cable core and an outer sheath, wherein the cable core consists of a radio frequency cable core and a control cable core, between which a hollow isolating support is arranged, the radio frequency cable core and the control cable core are supported on the hollow isolating support, the radio frequency cable core and the control cable core respectively consist of a conductor which is a copper clad aluminum conductor, namely, a copper layer is arranged at the periphery of an aluminum core, and an insulating layer, a polyester lapped layer and an aluminum composite shielding tape are sequentially arranged outside the conductor; and the outer sheath consists of an armor layer and a polyethylene layer. The utility model provides a novel communication cable which can prevent bird trouble and has strong corrosion resistance, high shielding property, low cost, strong anti-interference capability and diversified functions.
Description
Technical field
The utility model relates to a kind of signal transmitting apparatus, is specifically related to a kind of copper cover aluminum telecommunication cable.
Background technology
The major function of cable is used for transmission of audio, 150kHz and following analog signal and 2048kbit/s and following digital signal.Also can be used for transmitting the above digital signal of 2048kbit/s under certain condition.In recent years,, influenced the circuit normal communication, and increased to line crew and repair more than trouble repeatly because the telecommunication cable in woods area, rural area, various places is subjected to birds destruction in various degree.Because the happiness of this birds natural disposition is pecked, the built on stilts telecommunication cable in the jungle also regular meeting is taken as trunk and pips, and communication line often breaks down, and the cross-talk phenomenon gently then occurs, and is heavy then communication disruption takes place.
In addition, along with the laying of the new network of 3G, new requirement has been proposed telecommunication cable; Moreover, the electromagnetic wave power of various frequencies is increasing now, aspects such as the structure of cable, cost, antijamming capability have also been proposed new requirement, and present known telecommunication cable can not satisfy the development need of present telecommunication cable technology, is subjected to certain restriction in actual applications.
Be badly in need of now a kind ofly preventing bird pest and anti-corrosive properties are strong, shielding is high, cost is low, antijamming capability is strong, the novel telecommunication cable of functional diversities.
Summary of the invention
The purpose of this utility model just is to provide a kind of can prevent bird pest and anti-corrosive properties are strong, shielding is high, cost is low, antijamming capability is strong, the novel telecommunication cable of functional diversities.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of copper cover aluminum telecommunication cable, comprise cable core and oversheath, described cable core comprises radio frequency cable core and control cable core, between radio frequency cable core and control cable core, be provided with hollow isolation mount, radio frequency cable core and control cable core are supported on this hollow isolation mount, described radio frequency cable core and control cable core include conductor, conductor is a copper clad aluminum conductor, be that aluminium core periphery is provided with the copper layer, conductor is provided with insulating barrier outward successively, the polyester lapping layer, the plastic-aluminum mask tape, oversheath comprises armour, polyethylene layer.
As preferably: described insulating barrier is made by polyethylene, and described armour is made with galvanized steel strip by the armoured cable of GB4175.2 standard code.
As preferably: described hollow isolation mount is ellipticity.
As preferably: the polyethylene layer of oversheath also is provided with fluorescence coating outward.
Compared with prior art, advantage of the present utility model is: described cable core comprises radio frequency cable core and control cable core, and the cable core of various difference in functionalitys is concentrated in together, and can realize the control variation, improves the functional diversities of cable; Between radio frequency cable core and control cable core, be provided with hollow isolation mount, radio frequency cable core and control cable core are supported on this hollow isolation mount, by hollow isolation mount, not only can support various cable cores, the more important thing is these cable cores are carried out signal shielding, prevent that promptly these cable cores from transmitting interfere information each other, to improve communication quality; Described radio frequency cable core and control cable core include conductor, and conductor is a copper clad aluminum conductor, can reduce cost; Conductor is provided with insulating barrier, polyester lapping layer, plastic-aluminum mask tape outward successively, can improve antijamming capability; Oversheath comprises armour, polyethylene layer, can prevent bird pest.
