Abstract
The invention discloses an optical fiber unit for an optical fiber compound aerial phase line. The optical fiber unit for the optical fiber compound aerial phase line comprises a plurality of strands of optical fibers and a stainless steel sleeve which is arranged on the outer surfaces of the optical fibers in a surrounding mode, wherein the stainless steel sleeve is filled with optical fiber filling gel, and the cross section of the stainless steel sleeve is round or is of a fan shape.
Description
Technical field
The present invention relates to a kind of insulated cable, relate in particular to a kind of reinforced fiber composite high temperature resistant overhead insulated cable.
Background technology
as everyone knows, conventional aerial insulated cable adopts copper stranded conductor, aluminium stranded conductor, aluminium alloy stranded conductor, steel reinforced aluminium conductor etc. as conductor usually, outside conductor, the extruded insulation layer forms, wherein the tensile strength properties index of steel reinforced aluminium conductor conductor is best, can realize 1240Mpa-1410Mpa, but in rural area, mountain area, the utilizable air corridor in forest zone reduce gradually, shaft tower is apart from increase, the circuit ecological deterioration, line stress strengthens, the corresponding increasing of sag, significantly improve the requirement of circuit tensile strength, and conventional aerial insulated cable can't bear, and insulating barrier adopts polyvinyl chloride usually, polyethylene, crosslinked polyethylene etc., what wherein insulation property and temperature resistant grade were the highest is crosslinked polyetylene insulated, the long-term operating temperature that allows also is only 90 ℃, still can't meet the requirement that large load circuit is used, the aerial insulated cable that prior art is produced, do not there is communication function simultaneously, so original aerial insulated cable is function, lay on environment, all can't meet electric power system demand under the new situation on temperature resistant grade and current capacity, particularly can't meet the requirement of the strong intelligent grid of nation-building to novel overhead transmission line.
In recent years, cable enterprise has generally recognized the deficiency of aerial insulated cable self, all constantly exploring and improving, using sub-thread or steel wire strand as the center strengthening core as disclosed in Chinese patent 200820178715.6, then stranded aluminum or aluminum alloy conductor outside it, still do not have required resistance to tension; And the copper covered steel adopted in Chinese patent 200920208822.3 and the structure of aluminum-cladding stranded wire, this structure is born the still steel wire of pulling force, with aforementioned, compares, and there is no substantial improvement; Photoelectricity compound aspect; Chinese patent 200920231879.5 discloses the stainless steel tube fiber unit has been twisted in conductor; combination as communication with electric power; but it has been ignored under large intensity pulling force; circuit self can't be born the reliability service that enough pulling force are protected fiber unit; still can't meet the safe operation of aerial insulated cable under the complicated geographical environments such as mountain region, hills, not meet under the new situation " three height " requirement that tensile strength is high, the temperature rise current capacity is high, communication function stability is high to aerial insulated cable.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of reinforced fiber composite high temperature resistant overhead insulated cable that simultaneously has the functions such as communication, warning, information feedback is provided.
In order to solve technique scheme, the present invention adopts following technical scheme to be:
A kind of reinforced fiber composite high temperature resistant overhead insulated cable, it is characterized in that: comprise core, be surrounded with in the described core outside the first coating layer formed by fiber unit and the soft aluminium monofilament of a plurality of circle, and be surrounded with in the described first coating layer outside the second coating layer that the soft aluminium monofilament of a plurality of fan types forms.
Preferably, described core is the carbon fiber compound reinforced core.
Preferably, be surrounded with in the outside of described the second coating layer the temperature-resistant insulation layer formed by silicon rubber or fluoroplastics etc.
Owing to having adopted technique scheme, the present invention has following beneficial effect:
1), in the situation that the shaft tower span is constant, the tensile strength of aerial insulated cable self increases about twice, sag reduces 1/2nd, effectively solves the cable sagging problem;
2), outer adopt fan-shaped soft aluminium stranded conductor, with plain conductor, adopt the circular aluminum twisted wire to compare, in the situation that external diameter is equal, fan-shaped soft aluminium stranded conductor can increase aluminium cross section approximately 20%.D.C. resistance reduces by 17%, and AC resistance is also less, and ampacity can greatly improve and smooth surface, and wind pressure load in service is less, and surface is not-easy-to-freeze, the occurrence probability that can reduce to wave, and the self-damping performance is also better.
3), the conductance of carbon fiber compound reinforced core is zero, so can not produce the situations such as electromagnetic consumable and galvano-cautery, cable improves approximately 2 times useful life;
4), fiber unit under the strong protection of cable, can easily realize the functions such as communication, monitoring, warning, make circuit ruuning situation constantly in slave mode;
5), adopt the exotic materials such as silicon rubber or fluoroplastics as insulating barrier, the long-term permission operating temperature of aerial insulated cable is brought up to more than 180 ℃ unprecedentedly, not only can carry the current capacity of 1.5 times of conventional aerial insulated cables, also can effectively melt the ice and snow on cable.Guarantee the circuit security of operation.
