Abstract
The utility model discloses a light telephone system power supply cable with high anti-interference performance. The cable comprises a plurality of core wires twisted by a plurality of copper conductors. The plurality of core wires are disposed in a same plane and are arranged in parallel. The plurality of core wires are wrapped in a low-smoke halogen-free insulating layer with a rectangular cross section. An aluminum foil shielding layer with a rectangular cross section is wrapped round the external surface of the low-smoke halogen-free insulating layer. A plurality of high modulus polyethylene fiber are arranged at intervals between the low-smoke halogen-free insulating layer and the aluminum foil shielding layer. A copper-wire-woven shielding layer is wrapped round the external surface of the aluminum foil shielding layer. A sheath layer with a rectangular cross section is wrapped round the external surface of the copper-wire-woven shielding layer. The light telephone system power supply cable, which effectively resolves a defect of change in conductor diameter caused by stretch of a conventional cable and an interference problem caused by electromagnetic field generated by a conventional operating cable so that anti-interference performance and using security are substantially increased.
Description
Technical field
The utility model relates to the power cable field, is specifically related to a kind of lightweight telephone system service cable with high anti-interfering performance.
Background technology
Existing service cable is that the stranded conductor process is stranded, then insulation, 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 that conductor is through the circular configuration of 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 certain electromagnetic field around during the cable operation, thereby disturb other system, can cause equipment operation failure when serious.
Summary of the invention
The utility model purpose provides a kind of lightweight telephone system service cable with high anti-interfering performance, this telephone system service cable has solved the defective that existing cable causes the conductor wire diameter to change because of stretching effectively, greatly reduce production cost, and overcome the interference problem that existing cable generates an electromagnetic field because of the cable operation, thereby greatly improved the fail safe of interference free performance and use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of lightweight telephone system service cable with high anti-interfering performance, 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 described some heart yearns, one cross section is that the foil shielding layer of rectangle is coated on described low smoke and zero halogen insulating barrier outer surface, some high-modulus polyethylene fibres distribute alternately between described low smoke and zero halogen insulating barrier and foil shielding layer, one proof copper-wire braided screen is coated on described foil shielding layer outer surface, and a cross section is that the restrictive coating of rectangle is coated on described proof copper-wire braided screen outer surface.
It is as follows that technique scheme is further improved technical scheme:
1. in the such scheme, the number of described some heart yearns is 3.
2. in the such scheme, described proof copper-wire braided screen is formed by 18 bursts of tinned wird braidings, and described per share tinned wird is comprised of four tinned copper wires.
3. in the such scheme, described low smoke and zero halogen insulating barrier cross section length-width ratio is 1:3.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utlity model has the lightweight telephone system service cable of high anti-interfering performance, between insulation and sheath, increased aramid fiber as the stretch-proof original paper, efficiently solve the defective that the existing cable structure causes the conductor wire diameter to change because of stretching, thereby greatly improved the safety in utilization of cable; Secondly, adopt the shielding of aluminium strip and proof copper-wire braided, effectively solved the powerful electromagnetic field that existing cable produces when operation, thereby greatly improved the safety in utilization of cable; Again, 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.

Accompanying drawing 1 is for the utlity model has the lightweight telephone system service cable structural representation of high anti-interfering 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, proof copper-wire braided screen; 6, restrictive coating; 7, high-modulus polyethylene fibres.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of lightweight telephone system service cable with high anti-interfering performance, 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 described some heart yearns 2, one cross section is that the foil shielding layer 4 of rectangle is coated on described low smoke and zero halogen insulating barrier 3 outer surfaces, some high-modulus polyethylene fibres 7 distribute alternately between described low smoke and zero halogen insulating barrier 3 and foil shielding layer 4, one proof copper-wire braided screen 5 is coated on described foil shielding layer 4 outer surfaces, and a cross section is that the restrictive coating 6 of rectangle is coated on described proof copper-wire braided screen 5 outer surfaces.
The number of above-mentioned some heart yearns 2 is 3.
Above-mentioned proof copper-wire braided screen 5 is formed by 18 bursts of tinned wird braidings, and described per share tinned wird is comprised of four tinned copper wires.
