Abstract
The utility model discloses a high-tensile-property telephone system power supply cable with a flat structure, comprising a plurality of core wires respectively twisted by a plurality of copper conductors, the plurality of core wires are arranged on a same plane and arranged side by side, the plurality of core wires are wrapped by a low smoke halogen free insulating layer with a rectangular cross section, the outer surface of the low smoke halogen free insulating layer is wrapped by an aluminium foil shielding layer with a rectangular cross section, a plurality of aramid fibers are alternatively distributed between the low smoke halogen free insulating layer and the aluminium foil shielding layer, the outer surface of the aluminium foil shielding layer is wrapped by a copper wire weaved shielding layer, and the outer surface of the copper wire weaved shielding layer is wrapped by a sheath layer with a rectangular cross section. The high-tensile-property telephone system power supply cable with a flat structure can effectively overcome the defect that the conductor diameter of the prior cable easily change because of stretching, and can also resolve the problem that the prior cable easily generates electromagnetic field interference because of cable operation, thereby greatly increasing the anti-interference property and the use safety.
Description
Technical field
The utility model relates to the power cable field, is specifically related to a kind of telephone system service cable with high anti-interfering performance of flat structure.
Background technology
Common service cable is that the stranded conductor process is stranded, insulation then, and several groups are carried out sheath again, and this structure can produce powerful electromagnetic field when cable moves, thereby disturbs other system, and the cable of this circular configuration also is unfavorable for construction.
The structure of cable: the structure of common service cable is the circular configuration of conductor through the sheath that insulate again after stranded, in the power supply-distribution system and the distribution system in the building of the machine room that mainly is laid in.
Because the limitation of the above-mentioned circular configuration of cable; The wiring of cable brings many inconvenience in the power supply-distribution system of machine room and the distribution system in the building; Can produce the certain electromagnetic field around during the cable operation, thereby disturb other system, can cause the equipment operation fault when serious.
Summary of the invention
The utility model purpose provides a kind of telephone system service cable with high anti-interfering performance of flat structure; This telephone system service cable has solved the defective that existing cable causes conductor lines directly to change because of stretching effectively; And overcome the interference problem that existing cable generates an electromagnetic field because of the cable operation, thereby improved the fail safe of interference free performance and use greatly.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of telephone system service cable with high anti-interfering performance of flat structure; Comprise: some by the some strands of stranded heart yearns that form of copper conductor; These some heart yearns are positioned at same plane and parallel placement; One cross section is that the low smoke and zero halogen insulating barrier of rectangle coats said some heart yearns, and a cross section is that the foil shielding layer of rectangle is coated on said low smoke and zero halogen insulating barrier outer surface, and some aramid fibers distribute alternately between said low smoke and zero halogen insulating barrier and foil shielding layer; One copper wire woven shield is coated on said foil shielding layer outer surface, and a cross section is that the restrictive coating of rectangle is coated on said copper wire woven shield outer surface.
It is following that technique scheme is further improved technical scheme:
1. in the such scheme, the number of said some heart yearns is 3.
2. in the such scheme, said copper wire woven shield is formed by 18 bursts of tinned wird braidings, and said per share tinned wird is made up of four tinned copper wires.
3. in the such scheme, said aramid fiber specification is 1000D.
4. in the such scheme, said low smoke and zero halogen insulating barrier cross section length-width ratio is 1:3.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
The utlity model has flat structure high tensile and stretch the telephone system service cable of performance; Between insulation and sheath, increased aramid fiber as the stretch-proof original paper; Efficiently solve the defective that the existing cable structure causes conductor lines directly to change because of stretching, thereby improved the safety in utilization of cable greatly; Secondly, adopt aluminium strip and copper wire braid shielded, solved the powerful electromagnetic field that existing cable produces effectively when operation, thereby improved the safety in utilization of cable greatly; Once more, owing to adopt the flat cable structure, product is easy to carry, construction is simple,, greatly reduce the difficulty of construction, reduced the cycle of constructing.
Description of drawings
Accompanying drawing 1 is for the utlity model has the telephone system service cable structural representation that flat structure high tensile is stretched performance.
In the above accompanying drawing: 1, copper conductor; 2, heart yearn; 3, low smoke and zero halogen insulating barrier; 4, foil shielding layer; 5, copper wire woven shield; 6, restrictive coating; 7, aramid fiber.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: a kind of telephone system service cable with high anti-interfering performance of flat structure; Comprise: some by the some strands of copper conductors 1 stranded heart yearn that forms 2; These some heart yearns 2 are positioned at same plane and parallel placement; One cross section is that the low smoke and zero halogen insulating barrier 3 of rectangle coats said some heart yearns 2; One cross section is that the foil shielding layer 4 of rectangle is coated on said low smoke and zero halogen insulating barrier 3 outer surfaces; Some aramid fibers 7 distribute alternately between said low smoke and zero halogen insulating barrier 3 and foil shielding layer 4, and a copper wire woven shield 5 is coated on said foil shielding layer 4 outer surfaces, and a cross section is that the restrictive coating 6 of rectangle is coated on said copper wire woven shield 5 outer surfaces.
The number of above-mentioned some heart yearns 2 is 3.
Above-mentioned copper wire woven shield 5 is formed by 18 bursts of tinned wird braidings, and said per share tinned wird is made up of four tinned copper wires.
Above-mentioned aramid fiber 7 specifications are 1000D.
Above-mentioned low smoke and zero halogen insulating barrier 3 cross section length-width ratios are 1:3.
Adopt and above-mentionedly have flat structure high tensile when stretching the telephone system service cable of performance; Between insulation and sheath, increased aramid fiber as the stretch-proof original paper; Efficiently solve the defective that the existing cable structure causes conductor lines directly to change because of stretching, thereby improved the safety in utilization of cable greatly; Secondly, adopt aluminium strip and copper wire braid shielded, solved the powerful electromagnetic field that existing cable produces effectively when operation, thereby improved the safety in utilization of cable greatly; Once more, owing to adopt the flat cable structure, product is easy to carry, construction is simple,, greatly reduce the difficulty of construction, reduced the cycle of constructing.
