Abstract
The invention provides a shielding communication cable. A protection layer is arranged at the outermost layer of the cable, and two groups of core wires are arranged at the innermost layer of the cable; the core wires are wrapped by insulating material; a shielding layer is arranged between the protection layer and the insulating material; the shielding layer is made of shielding material by using alloy wires pulled from tin aluminum alloy; and the tin aluminum alloy consists of 1.5%-4.5% of tin, 0.1%-0.5% of rare earth elements, and the balance of pure aluminum. The cable is good in shielding effect, and also has electric property of communication cable.
Description
Technical field
The present invention relates to a kind of network or the practical cable of communication, be specifically related to a kind of transmission cable that uses Sn-Al alloy to make polymeric barrier layer materials.
Background technology
Be accompanied by the development of modern communication technology, the demand of signal high-frequency transmission particularly, between inside communication equipment and communication equipment, a large amount of high-frequency transmission modes are used, also produced a large amount of stronger electromagnetic interference, the distortion of signal transmission is therefore also more and more higher to the requirement of cable together, also can produce the mutual interference of signal phase between the cable.So, disturbed for anti-stop signal, guarantee signal transmission quality, a kind of jamming-proof transmission cable need to be provided.
Therefore, provide a kind of good shield effectiveness that has, the electric property that possesses again telecommunication cable simultaneously is those skilled in the art's urgent problems.
Summary of the invention
In order to solve the problems of above-mentioned existence, the present invention aims to provide a kind of good shield effectiveness that has, and possesses again the cable of the electric property of telecommunication cable simultaneously.
The invention provides a kind of shielded communication cable; the outermost layer matcoveredn of this cable; innermost layer is two core assembly lines; described heart yearn is by wrapped with insulation; between overcoat and the insulating material screen is arranged, the B alloy wire that described screen pulls into Sn-Al alloy is made the shielding material of screen, and the proportioning of Sn-Al alloy is: tin 1.5%-4.5%; rare earth element 0.1%-0.5%, all the other are fine aluminium.
Further, described Sn-Al alloy also comprises copper 1%-5%, magnesium 0.5%-2.3%.
Further, screen is to be formed by the B alloy wire braiding, and is provided with foil shielding layer between overcoat and insulating material.
Further, described overcoat is the environmental protection flame retardant polyvinyl chloride.
Further, internal layer is some communication transmission cables, overcoat close contact between each cable.
Further, described insulating material has the polyethylene foamed of low dielectric loss coefficient.
Further, described Sn-Al alloy also comprises copper 2%-4%, magnesium 0.5%-2.3%.
Further, described Sn-Al alloy also comprises copper 2%-4%, magnesium 0.8%-2.0%.
Further, described Sn-Al alloy also comprises copper 2%-4%, magnesium 1.5%-2.0%.
The invention provides a kind of shielded communication cable; the outermost layer matcoveredn of this cable; innermost layer is two core assembly lines; described heart yearn is by wrapped with insulation; between overcoat and the insulating material screen is arranged, the B alloy wire that described screen pulls into Sn-Al alloy is made the shielding material of screen, and the proportioning of Sn-Al alloy is: tin 1.5%-4.5%; rare earth element 0.1%-0.5%, all the other are fine aluminium.This cable has good shield effectiveness, possesses again the electric property of telecommunication cable simultaneously.
