Abstract
The utility model discloses an all dielectric self-supporting aerial cable. The all dielectric self-supporting aerial cable comprises a central structure, wherein the central structure comprises a fiber glass-reinforced plastics FRP, a plurality of optical fiber bundle tubes surrounding the FRP and covered by a binding belt and filled by a waterproof ointment, and a PE inner sheath, a tensile element and a PE outer sheath are arranged outside the binding belt in turn. The structure is optimized and the material of the tensile element is selected, thus the all dielectric self-supporting aerial cable has the following advantages: light weight, small external diameter, long mounting span, lightning strike resistance, no electromagnetic interference, and easy laying construction.
Description
Technical field
The utility model relates to a kind of power cable product, is specifically related to a kind of all-dielectric, self-supporting optical cable.
Background technology
In electric system; The optical cable that is laid on the high pressure overhead power line mainly contains two kinds of patterns; The one, optical fiber is maked somebody a mere figurehead composite ground wire (OPGW); The 2nd, all dielectric self-supporting is called for short ADSS (AlDielectricSelf-supporting) optical cable.On the existing ultra-high-tension power transmission line of existing aerial earth wire, or need not install and be suitable for the ADSS optical cable on the newly-built ultra-high-tension power transmission line of aerial earth wire and communicate transmission.Because it is in light weight that the ADSS optical cable has, external diameter is little, and the installation span is long, and anti-thunderbolt does not receive electromagnetic interference (EMI), is easy to advantages such as cable laying operation, in electric system and other related systems, obtains increasingly extensive use in recent years.
The environmental baseline of ADSS optical cable is decided according to the meteorological condition of laying area usually.The ADSS optical cable should use department to propose as one of design considerations according to the meteorological condition of locality by optical cable in various loading conditions.About temperature conditions, the serviceability temperature scope of ADSS optical cable is between-40 ° of C～+ 70 ° C usually.The utility model is primarily aimed at the structure Design and Calculation of existing ADSS optical cable, and selecting for use of material improved.
The utility model content
The purpose of the utility model is the shortcoming that overcomes prior art; A kind of optical cable is characterized in that, has division center: comprise FRP (fiberglass reinforcement); A plurality of optical fiber bundle tubes around the FRP setting; A plurality of optical fiber bundle tubes are coated by binder, between have greasy for preventing water to fill, set gradually PE inner sheath, an anti-element and the PE oversheath opened outside the binder.
Scheme further is: an anti-element is stranded in the restrictive coating by the Kevlar fiber and constitutes.
Description of drawings
Fig. 1 is the utility model embodiment optical cable sectional view.
1-FRP; The 2-optical fiber bundle tubes; The 3-greasy for preventing water; The 4-binder; The 5-PE inner sheath; The anti-element of opening of 6-Kevlar; The 7-PE oversheath.
Embodiment
In the design of the utility model All Dielectric self-support (see figure 1); Optical cable has division center: comprise FRP (fiberglass reinforcement); A plurality of optical fiber bundle tubes around the FRP setting; A plurality of optical fiber bundle tubes are coated by binder, between have greasy for preventing water to fill, set gradually PE inner sheath, an anti-element and the PE oversheath opened outside the binder.Wherein, one of characteristics of ADSS optical cable are because the suspension of its big span is laid, thus its tensile strain much larger than other optical cables, tensile strain can reach 0.6%～0.8% usually.Therefore, the cable core structure form of ADSS optical cable is advisable with pine pipe layer-stranding cable.Because in layer-stranding cable, optical fiber bundle tubes is stranded on the skeleton with spiral form, thereby the optical fiber in beam tube has a natural stretch to window.When being zero like the surplus length of optical fiber in beam tube, under static state, optical fiber is positioned at the beam tube center, and when the stressed extension of optical cable, optical fiber is shifted to the inwall that beam tube leans on skeleton one side, and does not receive stress.When optical cable shrank at low temperature, beam tube had the ability of bigger " accumulation " excess fiber length, and when optical cable was in extended state, beam tube had the ability of bigger " release " excess fiber length again, and the transmission performance of optical fiber is guaranteed in the larger context.Also can be eased to a certain extent to the precision to surplus long control in the beam tube processing conversely.Because the stretch modulus of FRP is 50GPa, less than the anti-stretch modulus 200GPa that opens the guiding principle silk of element of conduct in the conventional optical cable.Add that tensile force that the ADSS optical cable born is much larger than conventional optical cable.Thereby can not only rely on the FRP skeleton to be used as the anti-element of opening.A main anti-element is the aramid fiber that is stranded in the restrictive coating.Aramid fiber is a kind of aromatic polyamide fibre, because the unique chemical structure and the performance of this fibrid, wherein; Preferably, poly(p-benzamide) is that intensity is high in the aramid fiber, a kind of material that coefficient of thermal expansion is little; Be suitable for the strength materials of making optical cable, its tensile modulus is 120GPa.In the designing and calculating of ADSS optical cable, only take into account aramid fiber usually as strength members, that is calculate the optical cable strain with the tensile modulus E and the sectional area S thereof of aramid fiber in the cable configuration.And the FRP that in calculating, takes no account of as skeleton resists the contribution of opening to optical cable.Can the anti-Zhang Yinsu of FRP be considered as the strength assurance coefficient in the ADSS optic cable design like this.
In sum, the utility model ADSS optical cable has in light weight, and external diameter is little, and the installation span is long, and anti-thunderbolt does not receive electromagnetic interference (EMI), is easy to advantages such as cable laying operation.
Claims (2)
1. all-dielectric, self-supporting optical cable; It is characterized in that; Have division center: comprise fiberglass reinforcement FRP, around a plurality of optical fiber bundle tubes that FRP is provided with, a plurality of optical fiber bundle tubes are coated by binder; Between have greasy for preventing water to fill, set gradually PE inner sheath, an anti-element and the PE oversheath opened outside the binder.
2. according to the said optical cable of claim 1, it is characterized in that: a said anti-element is stranded in the restrictive coating by the Kevlar fiber and constitutes.
