Abstract
A copper-clad steel type optical fiber composite overhead ground wire comprises an optical fiber unit using a stainless steel pipe as a sleeve and a metal wire stranded outside the optical fiber unit, wherein the metal wire is a copper-clad steel core metal wire. The ratio of the cross-sectional area of the copper layer-clad steel core wire to the steel core may be selected between 0.2 and 2.0 depending on different requirements of use. The metal wire is a copper layer clad steel core metal wire, and has obvious advantages compared with the existing aluminum metal wire. The copper is not easy to corrode after being attached with condensed water in high altitude, and the corrosion resistance of the invention is strong; the melting point of copper is high, the copper is not easily melted by high temperature generated after the ground wire is struck by lightning, and the lightning strike resistance performance is excellent; the metal wire with the copper layer coated with the steel core structure can reduce the overall outer diameter of the ground wire, reduce the weight and reduce the sag of the ground wire. Therefore, the novel optical fiber composite overhead ground wire has longer service life and lower maintenance cost compared with the prior similar products.
Description
Technical field
The present invention relates to the overhead ground wire of a kind of high-altitude power transmission line, especially Optical Fiber composite overhead Ground Wire.
Background technology
The Optical Fiber composite overhead Ground Wire of high-altitude power transmission line has the dual-use function as the overhead ground wire of power transmission line and realization optical communication, this Optical Fiber composite overhead Ground Wire comprises with stainless steel tube makes the fiber unit of sleeve pipe and stranded metal wire outside fiber unit, existing metal wire is generally aluminum metal lines, as aluminium alloy wire, aluminium-clad steel wire etc.Optical Fiber composite overhead Ground Wire is in high aerial, adheres to condensed state water easily, and aluminum metal lines easily is corroded, and influences useful life.In order to address this problem, the general anticorrosion ointment of coating that adopts prevents that aluminum metal lines is corroded.But under the situation of climate variability, as the washing away of line over the ground of raining heavily, anticorrosion ointment is constantly diluted and is oozed out from the gap of ground wire; Dry, anticorrosion ointment can solidify and be ineffective.Therefore, applying anticorrosion ointment is difficult to achieve the goal.In addition, because the fusing point of aluminium is lower, the high temperature of the ground wire back generation of being struck by lightning makes aluminium that fusing takes place easily and generates molten spot, even fuses reduction of service life.
Summary of the invention
In order to overcome the deficiency of the Optical Fiber composite overhead Ground Wire that has the high-altitude power transmission line now, the invention provides a kind of copper-clad die Optical Fiber composite overhead Ground Wire, make aluminium that fusing takes place after the aluminum metal lines that can effectively solve ground wire is corroded easily and ground wire is struck by lightning easily and generate the problem of molten spot even fusing, the useful life of extended fiber composite overhead ground wire.
A kind of copper-clad die Optical Fiber composite overhead Ground Wire provided by the invention comprises fiber unit and the outer stranded metal wire of fiber unit of making sleeve pipe with stainless steel tube, and metal wire is a copper layer Baogang core metal line.
According to different instructions for uses, the copper layer of copper layer of the present invention Baogang core metal line and the cross-sectional area ratio of steel core can be selected between 0.2-2.0.
The invention has the beneficial effects as follows: metal wire of the present invention is a copper layer Baogang core metal line, has tangible advantage than existing aluminum metal lines.Copper is difficult for being corroded after height adheres to condensed state water in the air, and decay resistance of the present invention is strong; The fusing point of copper is higher, and the high temperature of the ground wire back generation of being struck by lightning is not easy to make copper to melt, and anti-thunderbolt performance is excellent; Use the metal wire of copper layer Baogang cored structure, can reduce the entire outer diameter of ground wire, weight reduction, the sag of minimizing ground wire.Therefore, the present invention is as the long service life of a kind of novel Optical Fiber composite overhead Ground Wire than existing like product, and maintenance cost is low.
