Background technology
The ordinary numbers cable: general data mode transmission digital cable is generally the transfer wire that adopts electrician's copper cash base to make through techniques such as drawing, annealing, adopts excellent polyolefins to coat and forms solid single line; Many solid single lines make up mutually, carry out stranded composition strand to line according to certain lay length of twist; Many strands according to the demand of comprehensive wiring, generally adopt 4～25 pairs of lines to line, carry out total stranded cable that forms into; In the outside that becomes cable, according to actual needs, general indoor cable extrudes one deck PVC polyvinyl chloride at last, and outdoor cable extrudes one deck PE polyethylene.
Along with the high speed development of data communication and information technology, the 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 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 our existing comprehensive wiring system, general use that 4 pairs of ordinary numbers cables 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.
Due to the said structure of cable and the limitation of wiring, therefore the impact when the high-frequency is more and more outstanding along with electromagnetic radiation and capacitive coupling, 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 is all 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 leak electricity, burn, final initiation fire.
Summary of the invention
The utility model provides a kind of high frequency composite cable with electric power and network transmission function, and this high frequency composite cable reduces the dielectric constant of insulating barrier, thereby reduction high frequency electromagnetic radiation and capacitive coupling are on the impact of cable; And the multiple cables such as integrated power cable and network cable in the single line cable have been avoided the defectives such as potential safety hazard effectively, have facilitated layout and the maintenance of cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high frequency composite cable with electric power and network transmission function comprises two the first copper conductors, two the second copper conductors;
Described two the first copper conductors all are coated with the first insulating barrier separately, and a single face aluminium foil layer coats this two the first insulating barriers;
Described two the second copper conductors all are coated with the second insulating barrier separately, if this second insulating barrier outer surface is coated with the insulation foaming layer with individual cavity, if this individual empty volume accounts for 50% of described insulation foaming layer volume;
It is surperficial that the polyester belt is coated on described the first insulating barrier, the second insulating barrier and several gasket for packings;
Armour is coated on described polyester belt outer surface;
External sheath layer is coated on described armour outer surface.
Further improvement technical scheme in technique scheme is as follows:
1, in 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 such scheme, described gasket for packing number is at least four.
3. in such scheme, described the second 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 utlity model has the high frequency composite cable of electric power and network transmission function, it reduces the dielectric constant of insulating barrier, thereby reduction high frequency electromagnetic radiation and capacitive coupling are on the impact of cable; Secondly, integrated power 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 facilitated layout and the maintenance of cable, has reduced potential safety hazard; Secondly, adopt the polyester belt to carry out moistureproof effect to whole cable unit, fastening whole cable unit, and improve to the full extent the insulation property of whole cable.
