Description
Technical field
The invention belongs to technical field of electric wires and cables, be specifically related to a kind of communication power supply aluminium core flame-retardant flexible electric cable.
Background technology
Communication power supply flexible cable is a kind of electric connection line that supplies of communications facility, in the distribution system of telecommunication bureau station, distribution box cabinet and so on, is widely used.Communication power supply not only requires to have good flexibility with flexible cable, to conveniently lay under situation, and requires to have desirable anti-flammability in narrow space or similarly, to adapt to the instructions for use under the harsh occasion of fire-protection rating.
Can in disclosed Chinese patent literature, be seen in by the technical information of flexible cable about communication power supply, for example CN201247632Y recommends have that " communication power supply is with fire-retardant, fire-resistant, shielding anti-interference flexible cable ", CN201302849Y provides " a kind of communication power supply flame-retardant refractory flexible electric cable ", CN202230791Y discloses " the flame-retardant crosslinking polyethylene insulated flexible cable of a kind of communication power supply ", CN202720953U introduces to be had " for watt form drag combustion shielded flexible cable of communication power supply ", CN202855416U discloses " communication power supply fire-resistant shield flexible cable " and CN202601277U disclosed " a kind of communication power supply flame-retardant flexible electric cable ", etc..
Although the communication power supply that is not limited to exemplify above respectively has corresponding technique effect with flexible cable, but there is following common shortcoming: one, due to all using stranded thin copper wire as conductor, and this conductor is called five class copper conductors by industry, thereby soft degree can not meet the desired requirement.And because pliability is poor, bending radius is restricted, thus at narrow space, hindered by immovable object and even when the occasion at the place of talking in a roundabout way and so on is laid, very easily affect speed of application; Its two, owing to generally selecting with copper as the conductor of flexible cable, thereby not only there is the blindness that rationally uses raw material aspect under technology prejudice, and cause the manufacturing cost of flexible cable large; Its three, due to heavy weight, thereby not only logistics transportation, the cost of storage in link are high, and workmen's labour intensity is large in laid processes, to consume cost of labor high.
In view of above-mentioned prior art, still have improved necessity, the applicant has done useful design for this reason, has formed technical scheme described below.
Summary of the invention
Task of the present invention is to provide a kind of and contributes to significantly to enter to increase flexibility and use embodiment and conveniently lay and promote adaptability when small space is laid, be conducive to avoid the blindness that conductor material is selected and use reduction manufacturing cost, be of value to remarkable weight reduction and use and save such as logistics, storage, cable laying operation expense and alleviate workmen's labour intensity and have and be convenient to embody excellent anti-flammability and use and ensure and use safe communication power supply aluminium core flame-retardant flexible electric cable.
Task of the present invention completes like this, a kind of communication power supply aluminium core flame-retardant flexible electric cable, comprise conductor and overlayed on the insulating barrier outside conductor, described conductor is to be that stranded that form and the sectional area of the naked aluminium wire of 0.20-0.45 ㎜ is 1.5-500mm by the diameter through annealing in process
2naked aluminium wire stranded conductor, described insulating barrier is flame-proof polyvinyl chloride.
The outermost layer of naked aluminium wire stranded conductor of the present invention is that left-hand is stranded, and direction of lay is between layers contrary.
The stranded joint square of naked aluminium wire stranded conductor of the present invention is 10～25 times of naked aluminium wire stranded conductor diameter.
The thickness of insulating barrier of the present invention is 0.7-2.8 ㎜.
One of technique effect of technical scheme provided by the invention, because stranded that form and the sectional area of naked aluminium wire that to have adopted by diameter be 0.2-0.45mm is 1.5-500mm
2naked aluminium wire stranded conductor as conductor, thereby flexibility significantly improved, minimum bending radius is the outside diameter of cable four times, in the time of cable laying operation, there is the good adaptability to the place such as small space, talking in a roundabout way; Two, owing under the prerequisite that has overcome technology prejudice, naked aluminium wire stranded conductor being substituted to the bare copper wire stranded conductor in prior art, thereby not only significantly reduced manufacturing cost, and the adaptability of ambient temperature is not affected when cable rated operational voltage and cable laying; Three, because overall weight is significantly alleviated for the copper conductor in prior art, thereby be conducive to reduce transport and storage and construction operation cost, and can alleviate workmen's operation intensity; Four, because insulating barrier is flame-proof polyvinyl chloride, thus can ensure use safety.
Brief description of the drawings
Fig. 1 is the cross sectional representation of embodiments of the invention structure.
Embodiment
Refer to Fig. 1, provided conductor 1 and overlayed on the insulating barrier 2 outside conductor 1.Technical essential as technical scheme provided by the invention: stranded that form and the sectional area of naked aluminium wire that conductor 1 is is 0.2-0.45mm by the diameter through annealing in process is 1.5-500mm
2naked aluminium wire stranded conductor, and insulating barrier 2 is flame-proof polyvinyl chloride, and thickness is 0.7-2.8mm.
The direction of lay between layers of above mentioned naked aluminium wire stranded conductor is: it is stranded that outermost layer should be left-hand, and it is contrary that the direction of lay between each layer keeps, in stranded process, be 10～25 times of naked aluminium wire stranded conductor diameter by twisting pitch control, being preferably 15～25 times, is 15～20 times better.
The communication power supply being obtained by embodiments of the invention is 450～750V and 600～1000V with the rated operational voltage of aluminium core flame-retardant flexible electric cable; Long-term work adaptive temperature is :-20 DEG C～70 DEG C; Minimum bending radius is four to 15 times of the outside diameter of cable, and wherein, non-armored type is to be greater than four times of the outside diameter of cable, and armored type is to be greater than 15 times of the outside diameter of cable.
A known class and two class aluminium conductors in conductor (being naked aluminium wire stranded conductor) and wires and cables industry that the present invention recommends have difference substantial and that be difficult to be come to realize by those of skill in the art, because a known class and two class aluminium conductors are commonly a class duralumin conductor and two class duralumin conductors in wires and cables industry.But, the present invention adopts 5 classes (five classes) ultra-fine aluminium monofilament is stranded and forms, adopting aforesaid diameter is the naked aluminium wire stranded conductor of 0.2-0.45 ㎜, the conductor of this structure in China's wires and cables industry up to now in space state, and there is no national standard and/or industry standard can follow, the applicant is applied to the cable that communication power supply is used, and has the positive effect that is confirmed the technique effect referring in superincumbent technique effect hurdle.
The relation preferably but between cross section, the radical of naked aluminium wire, the diameter of naked aluminium wire monofilament and the thickness of insulating barrier 2 of 18 kinds of specifications that are not limited to of above-mentioned conductor 1 is by shown in following table:
