The utility model discloses having a plurality of electrically conductive cables and communication optic fibre around wrapping in the oversheath, possessing power transmission and data communication transmit system simultaneously, electrically conductive core adopts light -duty aluminum alloy to make, can great length lay perpendicularly to have waterproof fire -resistant function, the cost is lower.
Description
Technical field
The utility model relates to power communication composite cable technical field, particularly a kind of aluminium alloy optical fibre composite electric power communication cable.
Background technology
At the power optical fiber of intelligent grid to after family (PFTTH) pilot terminates, Guo Wang company will carry out spread, except building at development, for also will transforming of the original community of part to " netting fusion; build intelligent residential district " more.The transfer function of the power cable that current China commonly uses is more single, mostly can only carry out the conveying of electric power energy, cannot accomplish the transmission to aspects such as user profile communications and feedback; And domestic fire-resisting cable adopts the wrapped fire-resistant isinglass belt of copper core conductor extruded insulation more substantially, fill and wrapped fire proofing, can realize cable to bear in certain fire process, again be energized as requested, cable still can work a period of time, but in fire process, inevitably act on cable from building collapsing or falling object, easily occur insulating barrier distortion or break, thus causing cable fault, after fire process terminates, cable cannot realize power supply capacity; In fire process, inevitably cause water in pipe burst or fire extinguishing procedure to enter cable insulation and conductor, thus cause cable cisco unity malfunction; And traditional fire-resisting cable is in vertical run process, because cable deadweight is too high, can not greater depth lay.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, a kind of aluminium alloy optical fibre composite electric power communication cable is provided, some conductor cable and communication optical fiber is surrounded with in its oversheath, possess electric power transfer and data communication transfer function simultaneously, conductive core material adopts Light Aluminum Alloy material to make, can greater depth vertical run, and there is water-and fire-proof function, cost is lower.
For solving the problem, the utility model provides following technical scheme:
A kind of aluminium alloy optical fibre composite electric power communication cable, comprise cable core and oversheath, some cable cores are surrounded with in oversheath, cable core comprises communication optical fiber and some conductor cable, conductor cable comprises the conductive core material be made up of aluminum alloy material and wrapped in the outer field core insulating barrier of conductive core material, and this core insulating barrier is that crosslinked polyethylene material is made.
Between some cable cores, also filler is provided with in oversheath; This filler is Ceramic silicon rubber packing.
Four conductor cable and a communication optical fiber is provided with in oversheath, communication optical fiber is G652D type optical cable, and communication optical fiber is arranged at the center of four conductor cable, and center adopts preformed support to fill, all isolated in the middle of every root core, be more conducive to the spaced heat of core.
Also be provided with a communication cable in oversheath, transfer of data can also be carried out by this communication cable.
Oversheath is sequentially Ceramic silicon rubber protective sleeve, tin plated steel wire braid and outer protective sleeve from the inside to the outside; in cabling process; cable acts directly on the tin plated steel wire braid of cable through line card; the steel wire braid of cable can bear the pulling force of cable self; by the upper end of steel wire braid and interlude after reasonably fixing; even if in fire hazard environment, cable also there will not be and fixedly gets loose, and is more conducive to the safe operation of cable in fire hazard environment.
The thickness of core insulating barrier is the 1/5-1/2 of conductive core material diameter.
Compared with prior art the beneficial effects of the utility model are:
Some cable cores are surrounded with in the utility model oversheath; cable core comprises communication optical fiber and some conductor cable; possess electric power transfer and data communication transfer function simultaneously; the core of conductor cable adopts aluminum alloy material to make; aluminium alloy conductor self has good mechanical performance index; weight is light-duty simultaneously; be more suitable for the vertical run of greater depth; lighter than adopting the cable weight of copper conductor when needing same ampacity; again by insulation protection two-layer inside and outside core insulating barrier and oversheath; have water-and fire-proof function, cost is lower.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Description of reference numerals: 1. communication optical fiber; 2. conductive core material; 3. core insulating barrier; 4. oversheath; 5. filler.
Embodiment
Below in conjunction with Figure of description and embodiment, embodiment of the present utility model is described in further detail:
With reference to a kind of aluminium alloy optical fibre composite electric power communication cable shown in Fig. 1, comprise cable core and oversheath 4, some cable cores are surrounded with in oversheath 4, cable core comprises communication optical fiber 1 and some conductor cable, conductor cable comprises the conductive core material 2 be made up of aluminum alloy material and wrapped in the outer field core insulating barrier 3 of conductive core material 2, the thickness of core insulating barrier 3 is the 1/5-1/2 of conductive core material 2 diameter, about 1-5 millimeters thick.This core insulating barrier 3 is made for crosslinked polyethylene material, crosslinked polyethylene has good heat resistance, insulation property, chemical-resistance and mechanical property, can not be able to decompose and carbonization below 300 DEG C, long service life, insulation property temperature influence is little, and dielectric loss angle tangent is very little, also there is acid and alkali-resistance, the advantage of combustion product environmental sound, the hardness of crosslinked polyethylene, rigidity, resistance to wear and shock resistance are all better than common plastic material in addition, and mechanical property is better.
Wherein, between some cable cores, filler 5 is also provided with in oversheath 4; This filler 5 is Ceramic silicon rubber packing.Four conductor cable and a communication optical fiber 1 is provided with in oversheath 4, communication optical fiber 1 is G652D type optical cable, and communication optical fiber 1 is arranged at the center of four conductor cable, and center adopts preformed support to fill, all isolated in the middle of every root core, be more conducive to the spaced heat of core.
