Abstract
The utility model relates to a composite low voltage power cable having a communication channel. The composite low voltage power cable comprises a cable core and a protection layer, wherein the cable core comprises three or four feeder wires, and one or two feeder wires are used for laying a silicon core pipe of the fiber. The silicon core pipe which is taken as a fiber communication channel is stranded with the feeder wires, after the cable is laid in place, the fiber can be distributed in the cable through an air-blowing method based on demands, moreover, the silicon core pipe has high mechanical strength, good high and low temperature resistance performance and quite small friction coefficient and requires no extra lubrication measurement. The composite low voltage power cable is not only convenient for cable laying, but also is applicable to slope and bending change.
Description
Technical field
The utility model relates to a kind of composite low-voltage power cable, specifically a kind of composite low-voltage power cable with communication port.
Background technology
In the strong intelligent grid that State Grid Corporation of China proposes, need to be take information platform as support, telecommunication optical fiber is as topmost passage, consumption is huge in the Intelligent Process of electricity consumption link, generally be to adopt to lay in addition optical cable and solve at present, this method is simple, but laying lightguide cable link quantities is large, and cost is high.At present more advanced technology is to adopt optical fiber composite low-voltage cable (being called for short OPLC), is a kind of the light unit to be compounded in the lv power cable, has the cable of electric power transfer and optical communication transmission combination.Stepped on such as " electric wire " magazine the 2nd periodical in 2011 in the literary composition of a piece " optical fiber composite low-voltage cable prospect forecast and technique " by name and just introduced this cable, it is comprised of cable core and the sheath of layer-twisted type structure, cable core is the main function components of optoelectronic composite cable, generally include the center stiffener, contain light unit, feed line, the gasket for packing of loose tube fiber, and prick the partly composition such as yarn, band.The advantage of this cable is that " electric power-optical fiber " only needs once construction, a passage to the family, has realized the problem that disposable solution cable is registered one's residence, and not only can save construction times, but also can save cable resource and conduit resource; Shortcoming is because optical fiber and the synchronous stranding of feed line are the protection bare fiber, improve mechanical strength and anti-little curved intensity of optical fiber, otherwise optical fiber is fragile when circuit additionally arranges.In addition, for the user who does not temporarily need optical fiber, increased line cost.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of composite low-voltage power cable with communication port is provided, and both can solve the problem that a linear construction line puts in place, can lay on demand optical fiber again, has advantages of that selectivity is good.
The utility model has adopted following technical scheme: have the composite low-voltage power cable of communication port, comprise cable core and sheath, comprise three or four feed lines in the cable core, it is characterized in that: also comprise one or two silicon core pipe that is used for laying optical fiber in the cable core.This cable is the same with common power cable when laying, and after cable laying puts in place, can by the air-blown installation method, telecommunication optical fiber be passed in the silicon core pipe at any time as required, thereby realizes optical fiber communication.
The wire diameter of considering feed line is too small, and to bear pressure excessive for silicon core pipe when stranding, easily extrusion, the single condctor nominal cross 〉=4mm of described feed line
2
Consider to make things convenient for optical fiber to be blown into silicon core pipe, its caliber φ is at 7～10mm.
The utility model will carry out twisted synthesizing cable as silicon core pipe and the feed line of optical-fiber communication channel, after cable laying puts in place, rely on air-blown installation, optical fiber is laid with power cable, optical fiber is sensitive for damages not, and when laying power cable, can make up the high-speed communicating network platform that covers the resident, the distribution link that can be intelligent grid provides passage.Compare with employing optical fiber composite low-voltage cable mode, use at fibre core has greater flexibility, economy and reasonability, simultaneously can also take full advantage of silicon core pipe more than needed, for " integration of three networks " of telecommunications network, radio network, the Internet can provide a kind of novel Fiber to the home mode, can effectively avoid the residential quarter Access Network by the generation of operator's monopolization situation; The in-depth application that also can be technology of Internet of things provides the communication network guarantee.In addition, adopt silicon core pipe to make optical-fibre channel, its mechanical strength is high, and the performance of high-and low-temperature resistance is good, and coefficient of friction is extremely low, does not need to take in addition lubricant method, both has been convenient to cabling, can adapt to again the gradient and the bending change of various landform.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is another example structure schematic diagram of the utility model.
Embodiment
By shown in Figure 1, comprise cable core and sheath, sheath is comprised of oversheath 1 and twining package tape 2, comprises three feed lines 3 and the HDPE silicon core pipe 4 as communication port in the cable core.Feed line 3 and silicon core pipe 4 adopt asymmetric stranding mode stranding.Feed line 3 is the wire of tape insulation layer, single condctor nominal cross 〉=4mm
2The caliber φ of silicon core pipe 4 is at 7～10mm.Position 6 is provided with filler between the feed line 3 and between feed line 3 and the silicon core pipe 4, and this filler can adopt gasket for packing.Cable core middle part 7 can arrange stiffener such as steel wire rope, perhaps places gasket for packing.After cable laying puts in place, rely on air-blown installation, optical fiber can be distributed in the passage 5 of silicon core pipe 4.
In embodiment illustrated in fig. 2, comprise four feed lines 3 and the HDPE silicon core pipe 4 as communication port in the cable core.
The utility model also can be placed two silicon core pipes in cable core, two silicon core pipes can be alternately distributed between feed line.
