Abstract
The utility model relates to an anti-erosion composite cable used for data transmission, which comprises an aluminum core and two copper leads; the aluminum core coats with a copper layer, the external surface of the copper layer is coated with an insulating layer; two copper leads are respectively coated with an insulation foaming layer, the external surface of the insulating layer is coated with the insulation foaming layer having several cavities, the volume of several cavities accounts for 50% of volume of the insulation foaming layer; a first aluminum foil layer coats two insulation foaming layers; a polyester belt layer coats with the insulation foaming layer and the first aluminum foil layer; an armor layer is coated with the external surface of the polyester belt layer; and a flame retardation layer is coated with the external surface of armor layer. The anti-erosion composite cable can reduce the high frequency electromagnetic radiation and influence of the capacitive coupling on the data communication; the transmission performance of cable can be improved, a coaxial cable and a network cable are integrated in one cable, and the arrangement and maintenance of the cable are convenient.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of anti-erosion composite rope for transfer of data.
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 anti-erosion composite rope for transfer of data, and this is anti-to corrode composite rope and can reduce high frequency electromagnetic radiation and capacitive coupling to the impact of cable, thereby improves the transmission performance of cable; And integrated coaxial cable and network cable in the single line cable have made things convenient for layout and the maintenance of cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-erosion composite rope for transfer of data, and described composite cable comprises aluminium core and two copper conductors;
Described aluminium core coats a bronze medal layer, and this copper layer outer surface is coated with insulating barrier;
Described two copper conductors all are coated with the insulation foaming layer separately, this insulating barrier outer surface is coated with has several empty insulation foaming layers, 50%, one first aluminium foil layer that these several empty volume accounts for described insulation foaming layer volume coats this two insulation foaming layers;
One polyester belt coats described insulating barrier 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 utility model is used for the anti-erosion composite rope of transfer of data, and it can reduce high frequency electromagnetic radiation and capacitive coupling to the impact of cable, thereby improves the transmission performance of cable; And 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, have made things convenient for layout and the maintenance of cable, have reduced potential safety hazard; Secondly, 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.
