Abstract

The utility model discloses an anti-erosion multifunctional transmission cable. The cable comprises an aluminum core, two first copper leads and two second copper leads. The aluminum core clads a copper layer. A surface of the copper layer is wrapped with an insulation foaming layer. The two first copper leads are wrapped with first insulating layers respectively. One single-sided aluminum foil layer wraps the two first insulating layers. The two second copper leads are wrapped with second insulating layers respectively. One inner sleeve layer wraps the surfaces of the two second insulating layers. A polyester belt layer wraps the surfaces of the copper layer, the first insulating layers and the inner sleeve layer 8. An armor layer wraps an external surface of the polyester belt layer. An outer sheath layer wraps the external surface of the armor layer. The armor layer is formed by a galvanized steel strip which longitudinally wraps the external surface of the polyester belt layer. The galvanized steel strip is coated with a polyester film layer. By using the multifunctional transmission cable of the utility model, mechanical strength of the cable is increased so that a service life is prolonged. Current cable clutter can be effectively avoided and arrangement and maintenance of the cable are convenient.

Description

The anti-Multifunctional conveying cable that corrodes

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of Multifunctional conveying cable of anti-erosion.

Background technology

Along with the high speed development of data communication and information technology, the improving constantly of the fast development of network technology and computing power, user's home terminal type is more and more, and this requirement to the comprehensive wiring system performance is also more and more higher.Network rate improves day by day, means the raising of operating frequency, easier generation 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.

In existing wiring system, 4 pairs of ordinary numbers cables of normal operation are surfed the Net, transfer of data etc., use local cable to advance wiring can to carry out the transmission of phone, voice etc., use common coaxial cable to carry out watching of Web TV, HDTV (High-Definition Television) etc., above cable need to influence each other in same pipeline concentric wiring, the phase mutual interference in wiring.

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, cause easily 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 Multifunctional conveying cable of anti-erosion, and this anti-Multifunctional conveying cable that corrodes increases the mechanical strength of cable, thereby increases the service life; And the multiple cables such as integrated coaxial cable, electric power cable and network cable have avoided existing cable mixed and disorderly effectively in the single line cable, have the defectives such as potential safety hazard, have made things convenient for layout and the maintenance of cable.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Multifunctional conveying cable of anti-erosion comprises the aluminium core, two the first copper conductors and two the second copper conductors;

Described aluminium core coats a bronze medal layer, and this copper layer surface is coated with the insulation foaming layer;

Described two the first copper conductors all are coated with the first insulating barrier separately, and a single face aluminium foil layer coats this two the first insulating barriers;

Described two the second copper conductors all are coated with the second insulating barrier separately, and an interior jacket layer is overlying on this two the second surface of insulating layer outward;

The polyester belt coats described copper layer, the first insulating barrier and interior jacket layer surface;

Armour is coated on described polyester belt outer surface;

External sheath layer is coated on described armour outer surface.

It is as follows further to improve technical scheme in the technique scheme:

1, in the such scheme, described armour is comprised of the vertical galvanized steel strip that is wrapped in described polyester belt outer surface, and this galvanized steel strip is coated with a laminated polyester film.

2. 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 anti-Multifunctional conveying cable that corrodes of the utility model, it increases the mechanical strength of cable, thereby increases the service life; Secondly, the multiple cables such as integrated coaxial cable, electric power cable and network cable have avoided existing cable mixed and disorderly effectively in the single line cable, 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; Again, adopt the polyester belt that whole cable unit is carried out moistureproof effect, fastening whole cable unit, and improve to the full extent the insulation property of whole cable.
