Abstract
The utility model relates to an ice and snow proofing overhead conductor, which is characterized in that: an extra-high tensile steel wire is used as a core wire; one, two or more layers of wires withZ-shaped or inverse Z-shaped cross sections are concentrically stranded outside the core wire; all gaps among the layers and among the wires are filled with the anti-corrosive water resistance factice. The utility model can be used as the overhead conductor for transmitting electric power and has the advantages that: adopting the extra-high tensile steel wire as the core wire can obviously improve tension resistance intensity; the Z-shaped or inverse Z-shaped wires are stranded to form the conducting layers, so that the surface is smooth, ice and snow cannot be easily detained and the ice andsnow proofing capacity can be obviously improved; the ice and snow proofing overhead conductor can guarantee that the electric fence cannot ice up and crack in bad rain and snow weather so as to operate safely.
Description
Technical field
The utility model relates to a kind of circuit that transmits electric power, and lead that especially can the anti-ice-snow disaster is the anti-ice-snow aerial condutor.
Background technology
Existing electric power overhead lead all is to be circular stranded the forming of single line by cross section, though with a long history, its weak point is that the slit is big between this lead line and the line, and the surface is crude, and snow easily freezes.Under normal circumstances can use, but picture runs under China in 2008 continuous freezing sleet hazard weather situation in south, ice and snow outside the lead is cumulative, increased the weight of the extra duty of lead, cause at last can't bear the heavy load and a large amount of fracture, make electrical network paralysis outage, bring to power circuit maintenance and people's productive life to have a strong impact on.
Summary of the invention
Be the crude deficiency of easily freezing snow, can not bear the special hazard weather of freezing sleet of the stranded conductive line surfaces of circle single line in order to overcome the prior art shape of cross section, the utility model provides a kind of anti-ice-snow aerial condutor, make it significantly strengthen resistance to tension, smooth surface, not-easy-to-freeze accumulated snow, adapt under the freezing sleet severe weather conditions and still can normally move, improve the security reliability of electrical network.
The technical scheme in the invention for solving the technical problem is: a kind of anti-ice-snow aerial condutor, by comprising the Extra High Strength steel core wire, shape of cross section is that Z-shaped or anti-Z-shaped lead and anticorrosion greasy for preventing water formed, it is characterized in that with the Extra High Strength steel wire be heart yearn, in its outside concentric stranding shape of cross section successively is Z-shaped or anti-Z-shaped lead, the shape of cross section of this lead is that inside and outside perimeter line is the concentric arcs line, adjacent sideline is the tortuous fan-shaped of radial transmission line, its Z-shaped or anti-Z-shaped seam filled up complementary engagement mutually, Z-shaped or the anti-Z-shaped lead of same shape is as one deck twisted wire, and the shape of cross section after this lead is stranded is a complete inside and outside smooth annular; The number of plies of this lead twisted wire is one deck, two-layer or multilayer, and when lead has more than two-layer when stranded, the left-handed or dextrorotation strand of adjacent ectonexine twisted wire is on the contrary, and the strand of outermost layer lead is to being dextrorotation; The radical of every layer conductor is 〉=2 positive integer; The layer of this lead with layer between, all clearance filled anticorrosion greasy for preventing water between line and the line.
The utility model is owing to adopted the Extra High Strength steel wire as heart yearn, significantly improved the tension strain insulator ability of lead, again because to have adopted cross section be that the Z-shaped or anti-Z-shaped lead of special shape is as outer twisted wire, the internal and external stopper shape of lead was filled up complementary engagement mutually, outer contact shape of cross section after stranded is a complete annulus, be seen as smooth cylindrical from appearance, be equivalent to a cross section and be circular smooth lead, sleet is difficult to be detained on so smooth lead, significantly improved the ability of anti-ice-snow, can not only be as the lead that generally transmits electric power, more can adapt to anti-ice-snow under freezing sleet disaster bad weather environment, safe transport electric power is guaranteed the safe operation of electrical network, has unrivaled superiority.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the transversal structural map of the utility model.
In Fig. 1: 1. Extra High Strength steel core wire, 2. shape of cross section is Z-shaped lead, 3. shape of cross section is anti-Z-shaped lead, 4. anticorrosion greasy for preventing water.
Embodiment
In Fig. 1: a kind of anti-ice-snow aerial condutor, comprise Extra High Strength steel core wire 1, shape of cross section is that Z-shaped lead 2, shape of cross section are that anti-Z-shaped lead 3 and anticorrosion greasy for preventing water 4 are formed, it is characterized in that with Extra High Strength steel wire 1 be heart yearn, is Z-shaped 2 or anti-Z-shaped 3 leads at the stranded shape of cross section of its outer concentric; The shape of cross section of above-mentioned lead is that inside and outside perimeter line is the concentric arcs line, adjacent sideline is the tortuous fan-shaped of radial transmission line, with the Z-shaped or anti-Z-shaped lead of shape as one deck twisted wire stranded after, because seam Z-shaped or anti-Z-shaped lead filled up complementary engagement mutually, the shape of cross section after this lead is stranded is a complete inside and outside smooth annulus; The number of plies of this lead can be one deck, two-layer or multilayer, when lead 2 or 3 has two-layerly when above, revolves strand about adjacent ectonexine lead on the contrary, but the strand that will make the outermost layer lead is to being dextrad; The radical of every layer conductor is 〉=2 positive integer; The layer of this lead with layer between, all clearance filled anticorrosion greasy for preventing water 4 between line and the line.
