Description
Technical field
The utility model relates to a kind of power cable, relates in particular to a kind of tension for building and supplies photoelectric compound cable.
Background technology
In the comprehensive building wiring, be used for the control cables of transmission of digital signals, its conductor is single core copper conductor, conductor in long-term use procedure owing to the factor such as oxidation, heating and hardening, becoming fragile; Network rate improves day by day, mean that the radiation that the raising of operating frequency produces is also more serious, can constantly there be simultaneously new electromagnetic interference source to produce in the surrounding environment, thereby affects the cable comprehensive wiring behind the family, the definition of the networking speed of family, telephone relation quality, high definition picture etc.; Signal transmission unit lacks center tension gasket for packing, cause cable when wiring because being stretched or when bending, electric property change and affect transmission performance; The common PVC material because of 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, so cable has larger limitation in the use.
The requirement of 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.
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 tension for building for photoelectric compound cable, and this tension can reduce the impact that high frequency electromagnetic radiation and capacitive coupling are communicated by letter on data for photoelectric compound cable; And increased the mechanical strength of cable, thereby increased the service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of tension for building supplies photoelectric compound cable, comprises two the first copper conductors, two the second copper conductors and several gasket for packings;
Described two the first copper conductors all are coated with the first insulation foaming layer separately, one single face aluminium foil layer coats these two the first insulation foaming layers, if this first insulation foaming layer has individual the first cavity, if this individual first empty volume accounts for 50～60% of described the first insulation foaming layer volume;
Described two the second copper conductors all are coated with the second insulation foaming layer separately, and this second insulation foaming layer has several the second cavities;
The polyester belt coats described the first insulation foaming layer, the second insulation foaming layer 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 improved technical scheme is as follows in the technique scheme:
1, in the such scheme, described the second cavity accounts for 50% of described the second insulation foaming layer volume.
2, in the such scheme, described gasket for packing number is four.
3. in the 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 utility model is used for the tension of building for photoelectric compound cable, and it can reduce the impact that high frequency electromagnetic radiation and capacitive coupling are communicated by letter on data, and has increased the mechanical strength of cable, thereby increases the service life; 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 made things convenient for layout and the maintenance of cable, has reduced potential safety hazard.
