Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of multipurpose electric power composite cable.
Background technology
The ordinary numbers cable: general data mode transmission digital cable generally is 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, easier generation 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 our 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, cause easily 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 multipurpose electric power composite cable, and this electric power composite cable can reduce high frequency electromagnetic radiation and capacitive coupling to the impact of cable, thereby improves the transmission performance of cable; And the multiple cables such as integrated coaxial cable and electric power cable have avoided existing cable mixed and disorderly effectively in the single line cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multipurpose electric power composite cable, and described composite cable comprises the aluminium core, two copper conductors;
Described aluminium core coats a bronze medal layer, and this copper layer is coated with insulating barrier;
Described two copper conductors all are coated with the insulation foaming layer separately, and this insulation foaming layer has several cavities, and this cavity volume accounts for 50 ~ 70% of described insulation foaming layer volume;
The polyester belt coats described insulating barrier and insulation foaming layer surface;
Aluminium foil layer coats described polyester belt;
Flame-retardant layer is coated on described aluminium foil layer outer surface.
Further improved technical scheme is as follows in the technique scheme:
1, in the such scheme, described empty volume accounts for 60% of described insulation foaming layer volume.
2, in the such scheme, described aluminium foil layer is the double-sided aluminum foil layer.
3, 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 utility model multipurpose electric power composite cable, it can reduce high frequency electromagnetic radiation and capacitive coupling to the impact of cable, thereby improves the transmission performance of cable; Secondly, integrated coaxial cable and electric power 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; Again, adopt the polyester belt that whole cable unit is carried out moistureproof effect, fastening whole cable unit, and improve to the full extent the insulation property of whole cable.
