Description
Technical field
The utility model relates to a kind of New Broadband Telecommunication Cable.
Background technology
Along with deepening continuously of China reform and opening-up, the fast development of economic construction, telecommunications have entered the new period of great development, will increase rapidly as the telecommunication cable demand of communication artery.Telecommunication cable spreads all over each corner as the critical elements of signal of communication transmission, so people are to the performance of telecommunication cable, improves day by day as performance demands such as fire-retardant, moistureproof, shieldings.
Telecommunication cable in the market be by several lines to being combined into cable core, the outside of cable core is with the sheath that one deck has the damp proof insulation antisepsis, each line to by copper conductor and on stranded the forming of insulating barrier.Though this class cable has stronger laser propagation effect, also there is following shortcoming in it:
1. the conductor of existing cable mostly has copper material to make, and the copper valency is high, certainly will cause the higher of cost;
2. existing cable mostly adopts single shielding, and shield effectiveness is limited;
3. existing cable mostly adopts the polyvinyl chloride oversheath, though the polyvinyl chloride oversheath has certain flame-retarding characteristic, its oxygen index only is about 30, in case breaking out of fire, very easily burning, and can produce a large amount of smog, be difficult to satisfy safety requirements and environmental requirement.
Summary of the invention
The utility model purpose is: a kind of New Broadband Telecommunication Cable is provided, and this cable adopts combined shielding, and promptly the plastic-coated aluminium foil adds the metal wire knitted shielding, with respect to single shielding, better shield effectiveness is arranged.
The technical solution of the utility model is: a kind of New Broadband Telecommunication Cable, comprise that several lines are right, line is to by outer stranded the forming of insulating barrier of two conductors and conductor, the right periphery of described several lines is provided with band, the periphery of band is provided with sheath, be provided with the combined shielding layer between band and the sheath, the combined shielding layer is made of aluminium foil and wire sheathing.
The further technical scheme of the utility model is: a kind of New Broadband Telecommunication Cable, comprise that several lines are right, line is to by outer stranded the forming of insulating barrier of two conductors and conductor, the right periphery of described several lines is provided with band, the periphery of band is provided with sheath, be provided with the combined shielding layer between band and the sheath, the combined shielding layer is made of aluminium foil and wire sheathing; Described conductor is by the aluminium core and be coated on the outer copper layer of aluminium core and constitute.
The more detailed technical scheme of the utility model is: a kind of New Broadband Telecommunication Cable, comprise that several lines are right, line is to by outer stranded the forming of insulating barrier of two conductors and conductor, the right periphery of described several lines is provided with band, the periphery of band is provided with sheath, be provided with the combined shielding layer between band and the sheath, the combined shielding layer is made of aluminium foil and wire sheathing; Described conductor is by the aluminium core and be coated on the outer copper layer of aluminium core and constitute; Be axially arranged with earth connection on the described band; Be axially arranged with on the inwall of described sheath and tear rope; Described sheath is made by the low-smoke halide-free fireproof composite polyolefine material of flame-proof PVC or environmental protection.
The utility model advantage is:
1, the utility model adopts combined shielding, and promptly the plastic-coated aluminium foil adds the metal wire knitted shielding, with respect to single shielding, better shield effectiveness is arranged.
2, the utility model can utilize the eddy current that produces in the metal material of low-resistivity when the frequency of interfere with electromagnetic field is higher, forms externally to come electromagnetic negative function, thereby reaches the effect of shielding.
3, the frequency of broadband cable transmission is higher, and when signal transmitted in conductor, because skin effect, signal mainly concentrated on the conductive surface transmission, so can adopt the conductor of copper cover aluminum as cable.Signal mainly transmits in the copper layer, have only a few signals in the relatively more weak aluminium conductor of electric conductivity, to transmit, very little to the laser propagation effect influence, but greatly reduce the cost of product, particularly, can create good economic benefits and social benefit in non-ferrous metal copper relatively nervous today.
4, sheath of the present utility model adopts the low-smoke halide-free fireproof composite polyolefine material of flame-proof PVC or environmental protection to make, and satisfies safety requirements or environmental requirement in the practical application, is convenient to enter the international market.
5. the utility model axially is provided with on the inwall of sheath and tears rope, so that can make things convenient for, promptly cut apart restrictive coating when using.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of conductor in the utility model;
Wherein: 1 line is to 2 conductors, 3 insulating barriers, 4 bands, 5 sheaths, 6 combined shielding layers; 7 earth connections; 8 tear rope;
21 aluminium cores, 22 bronze medal layers.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figure 1 and Figure 2, a kind of New Broadband Telecommunication Cable, comprise that several lines are to 1, line is to 1 by outer insulating barrier 3 stranded the forming of two conductors 2 and conductor 2, and several lines are provided with band 4 to 1 periphery, are axially arranged with earth connection 7 on the band 4, the periphery of band 4 is provided with sheath 5, be axially arranged with on the inwall of sheath 5 and tear rope 8, be provided with combined shielding layer 6 between band 4 and the sheath 5, combined shielding layer 6 is made of aluminium foil and wire sheathing.
Above-mentioned conductor 2 is by aluminium core 21 and be coated on the outer copper layers 22 of aluminium core 21 and constitute.Because the frequency of broadband cable transmission is higher, when signal transmitted in conductor 2, because skin effect, signal mainly concentrated on conductor 2 surface transmission, so can adopt the conductor 2 of copper cover aluminum as cable.Mainly transmission in copper layer 22 of signal, have only a few signals transmission in the relatively more weak aluminium core 21 of electric conductivity, laser propagation effect is influenced very little, but greatly reduce the cost of product, particularly, can create good economic benefits and social benefit in non-ferrous metal copper relatively nervous today.
Above-mentioned sheath 5 is made by the low-smoke halide-free fireproof composite polyolefine material of flame-proof PVC or environmental protection, satisfies safety requirements or environmental requirement in the practical application, is convenient to enter the international market.
The utility model adopts combined shielding 6, and promptly the plastic-coated aluminium foil adds the metal wire knitted shielding, with respect to single shielding, better shield effectiveness is arranged.
