Description

Buried communication cable is laid in a kind of fixation

Technical field

This utility model is related to a kind of cable, and buried communication cable is laid in specially a kind of fixation.

Background technology

Cable is widely used in electric power, communications, the complexity of the occasion being suitable for the continuous development of technology, cable Change, variation.At present, the structure of cable is generally multiple cores and is directly wrapped in insulant, does not deposit between adjacent core In spacing, so, during different signals transmits in respective core, electromagnetism between different signals, can be occurred to do Disturb phenomenon, have impact on the application of this cable, also do not possess corresponding heat-resisting ability and anti-wear performance simultaneously；And this kind of structure Cable, employs more insulant, brings unnecessary waste, and the resistance to compression resistance to tension of cable is poor.

China's subway Development of Underground Engineering in recent years, but because these site surrounding differences are so that people are to communication cable Prescription improves；Constantly improve in city, the attractive in appearance increasing cable for city is laid on underground.Use on market Cable, pliability extensibility is all bad, unstable chemcial property, corrosion-vulnerable and oxidation, the soil differing in the face of various soda acids Earth is difficult to adapt to.

For solving the above problems, therefore it is proposed that buried communication cable is laid in a kind of fixation.

Utility model content

The technical problems to be solved in the utility model is the defect overcoming prior art, provides a kind of fixation to lay buried logical News device.

In order to solve above-mentioned technical problem, this utility model provides following technical scheme:

Buried communication cable is laid in a kind of fixation of this utility model, including core conductor, insulating barrier, screen layer, tensile layer, fills out Fill layer, moisture-proof layer, lumarith, sheath and pe sheath, described core conductor outer wrapping insulating barrier, described insulating barrier is externally provided with screen Cover layer, described packed layer is evenly distributed in screen layer and centrally located tension lamellar spacing, and described moisture-proof layer wraps up packed layer And completely cutting off lumarith, described sheath is externally provided with pe sheath.

Further, described core conductor is copper solid conductor, and section is cylindrical and outer layer covers one circle copper sheet.

Further, described insulating barrier and screen layer group with highdensity polyolefine material and double-layer aluminum-foil paper tape Become.

Further, described tensile layer uses tension rope, and three groups of core conductors are stranded clockwise centered on tension rope to be formed.

Further, described packed layer and moisture-proof layer respectively block water petroleum jelly and polyester band.

Further, glass-cermic powder filled by described lumarith.

Further, described sheath by steel-tape armouring and covers the protective layer structure that the antifouling paint on armouring surface is formed Become.

The beneficial effect that this utility model is reached is: the use of copper core copper outer layer is conductor, material is resisted extraneous dry in itself The strong information transmission quality of ability disturbed is improved therewith with speed, by stranded clockwise around tension rope, in addition adopts steel band armour Dress, greatly improve cable flexibility, can curvature and comprcssive strength, be easy to arrange the complicated underground of transport, adaptation to the ground, core is led External side surrounds insulant arranging in pairs or groups and blocks water petroleum jelly and polyester band so that cable waterproof performance and ageing resistance obtain Strengthen, adaptively under clammy environment, different geographical soil acid-base degree is also different, by filling glass-cermic powder, improves cable Acid-proof alkaline, the use of pe sheath provides one layer of guarantee for the use of cable.

Specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated it will be appreciated that described herein excellent Select embodiment to be merely to illustrate and explain this utility model, be not used to limit this utility model.

Embodiment 1

As shown in figure 1, a kind of fixation lays buried communication cable, including core conductor 1, insulating barrier 2, screen layer 3, tensile layer 4th, packed layer 5, moisture-proof layer 6, lumarith 7, sheath 8 and pe sheath 9, described core conductor 1 outer wrapping insulating barrier 2, described exhausted Edge layer 2 is externally provided with screen layer 3, and described packed layer 5 is evenly distributed in screen layer 3 and centrally located tensile layer 4 gap, described Moisture-proof layer 6 parcel packed layer 5 simultaneously completely cuts off lumarith 7, and described sheath 8 is externally provided with pe sheath 9.

Described core conductor 1 is copper solid conductor, and section is cylindrical and outer layer covers one circle copper sheet, and solid copper diamagnetism is good It is difficult by outside electromagnetic interference efficiency of transmission height and the few wire of the high fault in material of clarity is soft, there is preferable extensibility, institute State insulating barrier 2 to form with highdensity polyolefine material and double-layer aluminum-foil paper tape with screen layer 3, water absorption is little, electric insulation Property excellent, the strong ageing resistace of adhesive force greatly improves, and described tensile layer 4 uses tension rope, and three groups of core conductors 1 with tension rope are Center is stranded clockwise to be formed, increased cable flexibility and can curvature, described packed layer 5 and moisture-proof layer 6 respectively block water Petroleum jelly and polyester band, the two cooperation is suitable for one inseparable water proof environment of offer, adapts to the underground ring of freezing Border, glass-cermic powder filled by described lumarith 7, has excellent acid-proof alkaline, wear-and corrosion-resistant isolation effect is good, described sheath 8 by Steel-tape armouring and the protective layer composition covering the antifouling paint formation on armouring surface, considerably increase the comprcssive strength of cable, It is easy to direct buried-pipe laying.

It should be understood that in order to increase cable flexibility or can curvature, the cable core of larger cross-section is by many relatively The single line of minor diameter is stranded to be formed.By many stranded core flexibilities of single line good, can curvature big, during core bending, in core Inside and outside heart line, two parts can be mutually mobile compensation, will not cause the plastic deformation of conductor, the therefore flexibility of core during bending Greatly improve with stability.

Finally it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this Utility model, although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art For, it still can be modified to the technical scheme described in foregoing embodiments, or to wherein some technical characteristics Carry out equivalent.All of the present utility model spirit and principle within, any modification, equivalent substitution and improvement made etc., all Should be included within protection domain of the present utility model.
