Description
Technical field
The utility model relates to a kind of coaxial cable, relates in particular to a kind of coaxial communication composite rope.
Background technology
Improving constantly of the fast development of network technology and computing power, user's home terminal type is more and more, and this requirement to the comprehensive wiring system performance is also more and more higher.Network rate improves day by day, means the raising of operating frequency, more easily produces electromagnetic radiation and capacitive coupling.Simultaneously, can constantly there be new electromagnetic interference source to produce in the surrounding environment, the radiation of the higher generation of network operating frequency is also more serious, and the equilibrium response of the non-shadow data cable of UTP has been not enough to offset electromagnetic radiation and the extraneous electromagnetic interference (Electro Magnetic Compatibility in the time of only satisfying 30～40MHz transfer of data) of express network itself.
In the existing comprehensive wiring system, 4 pairs of ordinary numbers cables of normal operation are surfed the Net, transfer of data etc., use local cable to advance wiring can to carry out the transmission of phone, voice etc., use common coaxial cable to carry out watching of Web TV, HDTV (High-Definition Television) etc., above cable need to influence each other in same pipeline concentric wiring, the phase mutual interference in wiring.
Because the said structure of cable and the limitation of wiring, therefore along with the impact when the high-frequency of electromagnetic radiation and capacitive coupling is more and more outstanding, had a strong impact on the electric property of each cable, cause each cable comprehensive wiring behind the family, the definition of the networking speed of family, telephone relation quality, high definition picture etc. all can be subject to impact in various degree, and because each cable all is separate unit, throughout the year month after month send out temperature, hot after, easily cause each cable sheath inter-adhesive etc., finally cause broken skin even electric leakage, burning, final initiation fire.
Summary of the invention
The utility model provides a kind of coaxial communication composite rope, this coaxial communication composite rope can reduce high frequency electromagnetic radiation and capacitive coupling to the impact of cable, and reduce the dielectric constant of insulating barrier, and then reach and reduce electric capacity, reduce the single line wire diameter, save material, reduce the purpose of cost.
For achieving the above object, the technical solution adopted in the utility model is: a kind of coaxial communication composite rope comprises aluminium core and two copper conductors;
Described aluminium core coats a bronze medal layer, and this copper layer outer surface is coated with the insulation foaming layer, and this insulation foaming layer has several empty insulation foaming layers, and these several empty volume accounts for 50% of described insulation foaming layer volume;
Described two copper conductors all are coated with the second insulating barrier separately, and one first aluminium foil layer coats this two insulating barriers;
One polyester belt coats described insulation foaming layer and the first aluminium foil layer;
One armour is coated on described polyester belt outer surface;
One flame-retardant layer is coated on described armour outer surface.
Further improved technical scheme is as follows in the technique scheme:
1, in the such scheme, described armour is comprised of the vertical galvanized steel strip that is wrapped in described polyester belt outer surface, and this galvanized steel strip is coated with a laminated polyester film.
2. in the such scheme, described copper conductor diameter is 0.5 ± 0.002 mm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The coaxial communication composite rope of the utility model, it can reduce high frequency electromagnetic radiation and capacitive coupling to the impact of cable, and reduces the dielectric constant of insulating barrier, and then reaches and reduce electric capacity, reduce the single line wire diameter, save material, reduce the purpose of cost; Secondly, integrated coaxial cable and network cable in the single line cable have avoided existing cable mixed and disorderly effectively, and there are the defectives such as potential safety hazard in difficult wiring, has made things convenient for layout and the maintenance of cable, has reduced potential safety hazard.
