Abstract
The utility model discloses a novel anti-corrosion optical fiber composite overhead ground wire, which comprises an optical fiber unit which uses stainless steel tube as a sleeve and an aluminum metalwire (aluminum alloy wire or aluminum-clad steel wire) which is stranded outside the stainless steel sleeve, and the outside of the stainless steel sleeve is coated with an aluminum coating. The aluminum coating coated at the outside of the stainless steel sleeve and the aluminum metal wire stranded at the outside of the sleeve are made of the same metal, therefore, the potential difference doesnot be formed; even though the condensed water is attached, the electrical current will not be formed between the same metal; the aluminum metal wire will not be eroded, and the service life of the composite overhead ground wire is extended.
Description
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, adhere to condensed state water easily, between two kinds of different metals, can form electric current, aluminium is in negative potential, steel is in positive potential, and aluminium will constantly be assembled to the steel of positive potential with ionic condition, and the surface of aluminium is destroyed, aluminum metal lines is corroded, and influences the useful life of 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.
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 novel anticorrosion Optical Fiber composite overhead Ground Wire, can effectively solve the problem that the aluminum metal lines of ground wire is corroded easily, the useful life of extended fiber composite overhead ground wire.
A kind of novel anticorrosion Optical Fiber composite overhead Ground Wire that the utility model provides comprises fiber unit and the outer stranded aluminum metal lines of stainless steel sleeve pipe of making sleeve pipe with stainless steel tube, in the outsourcing of stainless steel sleeve pipe the aluminium coating layer is arranged.
The beneficial effects of the utility model are: because stainless steel sleeve pipe of the present utility model outsourcing has the aluminium coating layer, making the aluminium coating layer and the outer stranded aluminum metal lines of sleeve pipe of stainless steel sleeve pipe appearance is same metal, can not form potential difference, even adhere to condensed state water, can not form electric current between the same metal yet, aluminum metal lines can not be corroded, the useful life of extended fiber composite overhead ground wire.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, aluminum metal lines, 2, the aluminium coating layer, 3, the stainless steel sleeve pipe, 4, optical fiber, 5, fiber unit.
Embodiment
With reference to Fig. 1, optical fiber 4 is located at makes fiber unit 5 in the stainless steel sleeve pipe 3, outside stainless steel sleeve pipe 3, extrude aluminium coating layer 2, aluminium coating layer 2 and stainless steel sleeve pipe 3 are combined closely to be integral, stranded aluminum metal lines (aluminium alloy wire or aluminium-clad steel wire) 1 outside the aluminium coating layer 2 of stainless steel sleeve pipe 3 is promptly made the utility model again.
Claims (1)
1. a novel anticorrosion Optical Fiber composite overhead Ground Wire comprises fiber unit and the outer stranded aluminum metal lines of stainless steel sleeve pipe of making sleeve pipe with stainless steel tube, it is characterized in that in the outsourcing of stainless steel sleeve pipe the aluminium coating layer being arranged.
