Abstract
The utility model relates to an environmental-protection through earth wire, which comprises a plurality of stranded metal round wires and sheathes arranged outside the metal round wires, wherein the periphery of each metal round wire is plated with a nickel alloy layer, and the sheathes are aluminium alloy sheathes. In the utility model, the aluminium alloy sheathes are adopted by the through earth wire, and aluminium alloy has the corrosion resistance and oxidation resistance; moreover, the aluminium alloy is nontoxic and can not pollute the environment and rivers; simultaneously, in order to prolong the service life of the through earth wire, the corrosion resistance of the railway through earth wire is further improved through plating the nickel alloy layer on the periphery of each metal round wire by the utility model, and thereby, the service life of the aluminium alloy metal sheath through earth wire is greatly prolonged to at least 60 years.
Description
Technical field
The utility model relates to a kind of railway signal cable, relates in particular to railway signal ground connection Through ground wire.
Background technology
Through ground wire is a kind of railway signal system cable of unified ground connection completely that is used for, it can make each working point earthing potential of large-scale Railway Electric system be consistent substantially, guarantee the safe and reliable ground connection of system equipment, eliminate because the current potential unsymmetrical current that the potential difference between the distinct device causes is realized the effective reliable protection to personnel and equipment.
Existing railway run-through ground line is made up of the naked copper single line of many mutually stranded settings and the lead sheath that envelopes many naked copper single lines, we know, though lead is the good especially metal material of a kind of Corrosion Protection, but because lead is heavy metal, poisonous because it is to be embedded in the railway soil along the line, year plumbous long afterwards can along with rain penetration in soil or river, this will pollute environment, and human body is caused damage.
The utility model content
The utility model purpose is that a kind of corrosion-resistant and Through ground wire of environmental protection relatively is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of environmental protection Through ground wire, comprise many mutually stranded round metal lines, be arranged on the sheath of many round metal line outsides, every described round metal line periphery plating has nickel alloy layer, and described sheath is an aluminum alloy sheath.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the utility model Through ground wire adopts aluminum alloy sheath, aluminium alloy has anticorrosive and antioxygenic property, and it is nontoxic, can not pollute environment and river, simultaneously, in order to increase the useful life of Through ground wire, the utility model is by the periphery plated nickel alloy-layer at the round metal line, further increased the corrosion resistance of railway run-through ground line, thereby increased the useful life of alloy aluminum metallic sheath Through ground wire greatly, can reach more than 60 years its useful life.
Description of drawings
Accompanying drawing 1 be according to technical solutions of the utility model concrete a kind of Through ground wire sectional view of implementing;
Accompanying drawing 2 be according to technical solutions of the utility model the concrete another kind of Through ground wire sectional view of implementing;
Wherein: 1, round metal line; 2, sheath; 3, nickel alloy layer;
1 ', round metal line; 2 ', sheath; 3 ', nickel alloy layer;
Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:
A kind of Through ground wire as shown in Figure 1, it is formed by the lead of 7 mutually stranded settings and with the sheath 2 that multiple conducting wires is coated on wherein, wherein, every lead is made up of at the nickel alloy layer 3 of round metal line 1 periphery round metal line 1 and plating, round metal line 1 is a copper cash, sheath 2 is an aluminum alloy sheath, its mode by cold extrusion or argon arc welding is coated on each lead periphery, the thickness of aluminum alloy sheath 2 can be chosen between 0.8～1.7mm according to concrete environment for use, and the thickness of described nickel alloy layer 3 is chosen between 0.2～0.5mm.
Shown in Figure 2 is another kind of Through ground wire, the difference of this Through ground wire and Through ground wire shown in Figure 1 is, be provided with 19 leads in its aluminum alloy sheath 2 ', every lead is made up of at the nickel alloy layer 3 ' of round metal line 1 ' periphery round metal line 1 ' and plating that copper product is made equally.
The Through ground wire of above-mentioned two embodiment has following advantage:
1, owing to adopt aluminum alloy sheath, make Through ground wire have environmental-protecting performance preferably;
2, because copper single line conductor adopts Nickel Plating Treatment, thus the useful life that has strengthened railway run-through ground line greatly;
3, owing to adopt the copper conductor and the aluminum alloy sheath of low-resistivity, make the electric conductivity of Through ground wire very excellent.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this; can not limit protection range of the present utility model with this; be not limited to adopt the mode of layer strand to arrange as multiple conducting wires; also can adopt concentric mode to be provided with; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
