Abstract

The utility model relates to a corrosion-resistant lightning-resistant optical fiber composite overhead ground wire, comprising an optical fiber unit with a stainless steel tube as a sleeve and aluminium wires twisted at the outside of the stainless steel sleeve, wherein an aluminium cladding layer and cladding layers formed by sector-shaped aluminium-clad steel wires are cladded between the stainless steel sleeve and the aluminium wires in sequence. The contacted surfaces among the aluminium cladding layer at the outside of the stainless steel sleeve, the cladding layers formed by the sector-shaped aluminium-clad steel wires and the aluminium wires at the outer layer are same metal, and do not form electric potential difference; and even though condensed water is adhered, current can not be formed among same metal, and the aluminium wires are not corroded. In addition, since the cladding layers formed by sector-shaped aluminium-clad steel wires are arranged tightly, the effective area of the cross section of the ground wire is increased, the lightning-resistant performance of the ground wire is improved, and the service life thereof is prolonged.

Description

Anticorrosive anti-thunderbolt Optical Fiber composite overhead Ground Wire
Technical field
The utility model relates to a kind of overhead ground wire of transmission line, especially Optical Fiber composite overhead Ground Wire.
Background technology
The Optical Fiber composite overhead Ground Wire of existing transmission line is stranded aluminum metal lines (as aluminium alloy wire, aluminium-clad steel wire etc.) and making outside the fiber unit of making sleeve pipe with stainless steel tube generally, and the stainless steel sleeve pipe directly contacts with aluminum metal lines, can form potential difference.Composite overhead ground wire is in high aerial, adheres to condensed state water easily, can form electric current between steel and two kinds of different metals of aluminium, and the surface of aluminium is destroyed, and aluminum metal lines is corroded, and influences the useful life of Optical Fiber composite overhead Ground Wire.In order to address this problem, generally prevent the electrochemical reaction that produces between different metal, with the useful life of extended fiber composite overhead ground wire with the anticorrosion ointment of coating.But under the situation of climate variability, as often the washing away of line over the ground of raining heavily, anticorrosion ointment is oozed out from the gap of ground wire by continuous dilution meeting; Dry, anticorrosion ointment can solidify and be ineffective.So, apply anticorrosion ointment and be difficult to achieve the goal.In addition, the anti-thunderbolt performance of existing fiber composite overhead ground wire is not high, and the outer stranded aluminum metal lines of its fiber unit is easily damaged by thunderbolt, causes whole Optical Fiber composite overhead Ground Wire normally not use.
Summary of the invention
In order to overcome the deficiency of the Optical Fiber composite overhead Ground Wire that has transmission line now, the utility model provides a kind of anticorrosive anti-thunderbolt Optical Fiber composite overhead Ground Wire, the aluminum metal lines that can effectively solve ground wire is corroded and the problem of easily being damaged by thunderbolt, the useful life of extended fiber composite overhead ground wire easily.
A kind of anticorrosive anti-thunderbolt Optical Fiber composite overhead Ground Wire that the utility model provides, comprise fiber unit and the outer stranded aluminum metal lines of stainless steel sleeve pipe of making sleeve pipe with stainless steel tube, be extruded with the aluminium coating layer in stainless steel sleeve pipe appearance, between aluminium coating layer and aluminum metal lines, be surrounded by the coating layer that constitutes by fan-shaped aluminium-clad steel wire.
The beneficial effects of the utility model are: because stainless steel sleeve pipe appearance of the present utility model is extruded with the aluminium coating layer, between aluminium coating layer and aluminum metal lines, be surrounded by fan-shaped aluminium-clad steel wire coating layer, making the surface that contacts with each other between the aluminium coating layer of stainless steel sleeve pipe appearance and fan-shaped aluminium-clad steel wire coating layer and the outer field aluminum metal lines three is same metal, can not form potential difference, even adhere to condensed state water, can not form electric current between the same metal, aluminum metal lines can not be corroded yet.In addition, fan-shaped aluminium-clad steel wire coating layer increases the effective area of the cross section of ground wire owing to arrange closely, has improved the anti-thunderbolt performance of ground wire, increases the service life.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model, and aluminum metal lines wherein adopts aluminium-clad steel wire.
In Fig. 1,1, the steel wire of aluminium-clad steel wire, 2, fan-shaped aluminium-clad steel wire coating layer, 3, the stainless steel sleeve pipe, 4, optical fiber, 5, the aluminium coating layer, 6, the aluminium covering of aluminium-clad steel wire, 7, the steel wire of fan-shaped aluminium-clad steel wire, 8, aluminium-clad steel wire, 9, fan-shaped aluminium-clad steel wire, 10, fiber unit.
Embodiment
With reference to Fig. 1, optical fiber 4 is located at makes fiber unit 10 in the stainless steel sleeve pipe 3, outside stainless steel sleeve pipe 3, extrude aluminium coating layer 5, aluminium coating layer 5 and stainless steel sleeve pipe 3 are combined closely to be integral, outside aluminium coating layer 5, coat fan-shaped aluminium-clad steel wire 9 again and constitute fan-shaped aluminium-clad steel wire coating layer 2, stranded aluminium-clad steel wire 8 outside fan-shaped aluminium-clad steel wire coating layer 2 is promptly made the utility model then.
