Description

A kind of interior hexagonal ADSS communications optical cables

Technical field

The utility model is related to the communications fields, and in particular to a kind of interior hexagonal ADSS communications optical cables.

Background technology

With the development of power communication, more and more optical cables are used in power communication line.Relative to conventional type Number optical fiber cable, ADSS All Dielectric self-supports can high pressure, high temperature environment in work.

Existing ADSS optical cables usually by cable core and are wrapped in the multi-protective layer of cable core periphery and constitute, each protective layer by Often there is slip phenomenon between layers in material difference, influences the reliability that ADSS optical cables transmit information, and drop The usage time of low ADSS optical cables virtually increases power grid and is laid with cost

In addition, ADSS communications optical cables are generally by it in the tower bar of high voltage transmission line, and due to electric power pylon pole span It is larger, it needs to reduce optical cable weight to the greatest extent, reduces pulling force caused by its dead weight, extend optical cable service life.And for interior Optical cable, volume is big, occupies wiring space, also increases maintenance difficulties and maintenance cost.

Utility model content

It is compact-sized the technical problem to be solved by the present invention is to provide a kind of interior hexagonal ADSS communications optical cables, outside Diameter is small, saves material, at low cost, light-weight, and unique interior hexagonal structure design can avoid the slippage between every layer of sheath, and And drag performance with excellent tension.

In order to solve the above-mentioned technical problem, the utility model provides interior hexagonal ADSS communications optical cables, including cable core and packet Wrap up in the sheath of cable core；The cable core includes the nonmetallic strengthening core being arranged from inside to outside, microbeam pipe；The microbeam pipe is more, It include multifiber in the every microbeam pipe；The sheath includes inner sheath and oversheath；The inner sheath is regular hexagon Sheath, the oversheath are interior hexagonal sheath and are fitted closely with the inner sheath.

Further, the inner sheath includes non-metal reinforced layer and the aramid yarn that wraps up the non-metal reinforced layer Layer.

Further, the aramid yarn layer outer wrapping water blocking layer.

Further, it is provided with tear rope in the water blocking layer.

Further, the nonmetallic strengthening core is KFRP strengthening cores.

Compared with prior art, the utility model has the beneficial effects that：

1, optical cable uses a kind of special interior hexagonal structure in the utility model, and this design is so that between each layer sheath More closely, structure is more firm, can avoid the slippage between every layer of sheath for contact.

2, in the utility model relative to traditional circular optical cable, greatly save material, not only reduce expense cost, but also make It is more light and handy to obtain optical cable.

3, the utility model uses micro- bundle tube structure, and cable core is more compact, and optic cable diameter is small.

4, the nonmetallic strengthening core of the utility model use so that the optical cable have good tensile property.

5, there are certain the air gaps between the utility model microbeam pipe and its housing, enhance the flexible of the optical cable Degree, has good anti-cushion performance.

6, the utility model waterstop and aramid yarn are used in combination so that the optical cable can waterproof it is high pressure resistant.

7, it is also surrounded by tear rope in the utility model waterstop, resists the ability that pulls with good, and energy absorbing cable makes With the heat distributed in the process.

Description of the drawings

For the clearer technical solution illustrated in the utility model embodiment technology, embodiment technology will be retouched below Attached drawing needed in stating is briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model Some embodiments, for those of ordinary skill in the art, without creative efforts, additionally it is possible to according to These attached drawings obtain other attached drawings.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the external protection structural schematic diagram of the cable core of the utility model.

Wherein, 1- optical fiber, 2-KFRP strengthening cores, 3- microbeam pipes, 4- non-metal reinforced layers, 5- aramid yarn layers, 6- waterstops, 7- oversheaths, 8- tear ropes, the positive hexagonal external protections of 9-, 10- circle external protections.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Embodiment based on this in practical, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

Embodiment

Referring to Fig.1, the utility model discloses a kind of interior hexagonal ADSS communications optical cables, by cable core, inner sheath, oversheath group At.Inner sheath is positive hexagonal sheath, and oversheath is interior hexagonal sheath.Cable core includes optical fiber 1, KFRP strengthening cores 2 and microbeam pipe 3. Wherein, KFRP strengthening cores are hexagon, and six face of side wall bears against the microbeam pipe of six roots of sensation package fiber optic bundle, every pipe 12 in microbeam pipe Core, totally 6 pipe, microbeam pipe outside diameter are 1.3 ± 0.05mm or so, and using LSZH sheaths, spatial arrangement is close.Hexagon sheath includes Non-metal reinforced layer 4, aramid yarn layer 5, waterstop 6.Microbeam pipe can be fixed and be wrapped up by hexagon non-metal reinforced layer 4, microbeam Pipe is not easy play displacement.Coat aramid yarn 5 and the waterstop 6 for capableing of waterproof successively outside non-metal reinforced layer 4.This hexagon Structure is relative to traditional circular configuration, since the presence of six corner angle makes the package between each layer sheath more closely, Avoid the slippage between every layer of sheath.It is additionally provided with tearing rope 8 in waterstop, can be dragged with tension and absorbing cable uses process In the heat that distributes.Oversheath 7 is in interior hexagon, and the outer wall of inner wall and inner sheath tightly fastens, and makes oversheath and inner sheath It fits closely contact to be not easy to slip, the utility model uses HDPE oversheaths.

ADSS communications optical cables are subjected to dead weight and external load, therefore to optical cable itself as All Dielectric self-support Weight demands it is high.The present embodiment use very cleverly in hexagonal construction the contact of every layer of sheath can not only be made more tight Close, cable core capacity bigger can also save material, mitigate the weight of optical cable.Such as the external protection structural representation that Fig. 2 is cable core Figure.Positive hexagonal external protection 9 and traditional round external protection 10 in comparison diagram, it can be seen that positive hexagonal external protection 9 is more To save material, and optical cable is as a kind of multilayered structure, and in the case where every layer of protective layer saves material, overall weight is just significantly It reduces.ADSS communications optical cables in the present embodiment are more light and handy, cost reduction, and weight is small.

The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new Type.Various modifications to these embodiments will be apparent to those skilled in the art, and determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest range consistent with novel point.
