Description
Technical field
The utility model relates to a kind of flat type cable, and the flat type electric wire of especially a kind of low-smoke non-halogen flame-retardant belongs to the power cable technical field.
Background technology
Flat type electric wire is a kind of transmission of electricity and communication cable commonly used at present,, signal antijamming capability easy to make owing to it is used widely by force, but it often has following defective: 1, existing flat type electric wire generally adopts the polyvinyl chloride of Halogen as the making material of insulating barrier and oversheath, in case breaking out of fire, the polyvinyl chloride of Halogen can produce a large amount of smog and pernicious gas, and human body, equipment are caused huge injury, hinders the carrying out of rescue work; Two, along with development of times, it is the inherent requirement of development intelligent grid that optical fiber is registered one's residence, and in existing transmission of electricity and communication cable and non-fiber, therefore can only carry out optical fiber by the optical cable of special use to transmit, and fails between optical cable and the existing flat type electric wire effectively to merge; Three, there is not video line in the existing flat type electric wire, can not satisfy the needs that family lives; Four, existing flat type electric wire bears, bearing is poor, is broken easily, brings very big trouble to production.
In view of above-mentioned ubiquitous defective, can design, produce the flat type electric wire of a kind of novel low-smoke non-halogen flame-retardant, to remedy the above-mentioned defective of existing flat type electric wire, be the technical barrier that those skilled in the art face.
Summary of the invention
The utility model aims to provide the flat type electric wire of a kind of low-smoke non-halogen flame-retardant, improves its anti-flammability, anti-load-bearing force-bearing property, reduces burning harm, and satisfies optical fiber and video transmission needs.
Its technical scheme that adopts is as follows: the flat type electric wire of this low-smoke non-halogen flame-retardant comprises: copper wire twisted wire, fiber unit, insulating barrier, mica tape, strengthening core, oversheath and video line; Wherein, the cross section of oversheath is pancake, copper wire twisted wire, fiber unit, strengthening core and video line are arranged side by side in it, strengthening core is in the center, it is distributed with fiber unit and video line on one side, another side is distributed with at least one copper wire twisted wire, and copper wire twisted wire, fiber unit and video line outer surface be enclosed with insulating barrier respectively, is provided with mica tape between fiber unit and the insulating barrier.
Preferably, insulating barrier and oversheath all adopt the polyethylene of ground cigarette halogen-free flameproof to make.
Preferably, the lapping direction of mica tape is dextrorotation, and employing is put up wrapped, and it is put up size and is 10%～15% of twining package tape width, and wrapping angle is 25 °～40 °.
Preferably, described strengthening core is for tearing rope.
The utility model advantage compared to prior art is: 1, flame-retardant; 2, the load-bearing of self, the ability that bears are strong; 3, the gas of burning generation reduces greatly to the harm of human body, equipment; 4, possess optical fiber and video transfer function.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1, copper wire twisted wire; 2, fiber unit; 3, insulating barrier; 4, mica tape; 5, strengthening core; 6, oversheath; 7, video line.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified: as shown in Figure 1, the flat type electric wire of this low-smoke non-halogen flame-retardant comprises: copper wire twisted wire 1, fiber unit 2, insulating barrier 3, mica tape 4, strengthening core 5, oversheath 6 and video line 7; Wherein, the cross section of oversheath 6 is pancake, copper wire twisted wire 1, fiber unit 2, strengthening core 5 and video line 7 are arranged side by side in it, the center is strengthening core 5, one side of strengthening core 5 is distributed with fiber unit 2 and video line 7, another side is distributed with at least one copper wire twisted wire 1, and copper wire twisted wire 1, fiber unit 2 be enclosed with insulating barrier 3 respectively with video line 7 outer surfaces, is provided with mica tape 4 between fiber unit 2 and the insulating barrier 3.
The stranding rotation direction of copper wire twisted wire 1 is left-handed or dextrorotation.
Insulating barrier 3 is polyethylene layer, and low smoke and zero halogen and possess fire retardation prevents in the time of insulation that copper wire, video line, optical fiber from scattering.
The effect of mica tape 4 is fire-retardant, prevents scattering of fiber unit 2 simultaneously.Its lapping direction is dextrorotation, and employing is put up wrapped, and it is put up size and is 10%～15% of twining package tape width, and wrapping angle is 25 °～40 °.
Strengthening core 5 for example adopts and tears rope, when playing good load effect, guarantees the overall bulk softness of electric wire, because it is in the center of whole flat type electric wire, thereby can play good load effect, and can certainly in oversheath 6, establish several strengthening cores more, strengthen force-bearing property.
Oversheath 6 adopts the injection mouldings of polythene material one to form, low smoke and zero halogen and possess fire retardation.
Result of the test shows, the load-bearing of the utility model self, the ability that bears are strong, possess optical fiber and video transfer function, and flame-retardant, and the gas that burning produces is little to the harm of human body, equipment.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
