Abstract
The utility model discloses an environment protection anti-corrosion transfixion ground-plane aerial which comprises a core thread. The core thread is at least two copper stranded conductors which are wringed with each other. The inner anti-corrosion layer which has been soaked in the anti-corrosion fluid and formed by oxidation is covered on the surface of the core thread; an outer anti-corrosion layer is provided outside the inner anti-corrosion layer. With good anti-corrosion performance, the utility model uses two layers for anti-corrosion, which has no pollution.
Description
Technical field
The utility model relates to the electric wire field, especially a kind of environment friendly corrosion protection type Through ground wire.
Background technology
In railway construction, in order to guarantee to realize between each system, the equipment such as communication, signal, electric power, traction power supply that equipotential connects, eliminate between distinct device, the system because the person and device security hidden danger that the potential difference existence causes need be buried Through ground wire underground in trunk railway whole process.At present, the China railways Through ground wire generally adopts outer lead-sheathing of copper stranded conductor or terne metal.Because ground wire is embedded in the soil layer, year plumbous long afterwards can along with rain penetration in soil or river, environment is caused severe contamination, the antiseptic property of ground wire is affected.
Summary of the invention
The utility model is intended at above-mentioned the deficiencies in the prior art, provides that a kind of double-decker is anticorrosion, environment friendly and pollution-free, antiseptic property and the environment friendly corrosion protection type Through ground wire that conducts electricity very well.
To achieve the above object of the invention, the utility model has adopted following technical scheme:
A kind of environment friendly corrosion protection type Through ground wire comprises heart yearn, and described heart yearn is at least two copper stranded conductors that twist together, and it is characterized in that: the heart yearn surface internal layer anticorrosive coat that oxidation forms in being soaked in impregnating fluid is coated on the heart yearn; Described internal layer anticorrosive coat is outside equipped with outer anticorrosive coat.
Described outer anticorrosive coat is copper alloy layer, aluminium lamination or aluminium alloy layer.
Heart yearn is soaked in and does the DX preservative treatment in the impregnating fluid, and the DX preservative treatment is the chemical oxidation treatment of copper stranded conductor, and copper generates thin on its surface and closely, combines firm internal layer anticorrosive coat with the copper stranded conductor parent metal through oxidation processes, and its concrete composition is CuO, Cu
2O, CuS or their mixture.
When outer anticorrosive coat is aluminium and aluminium alloy layer, adopt continuously extruded coating technology, outer anticorrosive coat bar is pressed into seamless pipe through cold-extruded, draw again and dial, outer anticorrosive coat closely is coated on outside the internal layer anticorrosive coat.
When outer anticorrosive coat is copper alloy, adopt the argon arc welding coating technology, outer anticorrosive coat band is drawn dial moulding, form tubulose, be welded into pipe by argon arc welding, through pricking line, be coated on the internal layer anticorrosive coat surface again.
Advantage of the present utility model is:
1, because the utility model adopts inside and outside double layer anticorrosive layer, the antiseptic property of Through ground wire is improved greatly, increase useful life.
2, because outer anticorrosive coat adopts copper alloy, aluminum or aluminum alloy layer, more existing lead alloy is environment friendly and pollution-free, antiseptic property good.
3, because inside and outside layer anticorrosive coat electric conductivity is plumbous higher than existing, the Through ground wire electric conductivity is improved greatly.
