Abstract
The utility model discloses a grounding through ground wire. The grounding through ground wire comprises a conductor (1) and a copper alloy sheath (2). The conductor (1) is formed by compacting and twisting multiple wires. The copper alloy sheath (2) is wrapped around the conductor (1) and is wrapped in an anticorrosive layer (3). The grounding through ground wire is formed by compacting and twisting multiple wires so as to achieve facts of effectively increasing the radial contact area between the conductor interior and the copper alloy sheath, reducing the contact resistance between the through ground wire and the copper alloy sheath, namely reducing the ground resistance of the through ground wire, and reinforcing the fault current drainage effect of the through ground wire. In addition, the copper alloy sheath has good corrosion resistance, oxidation resistance, and flame resistance and is capable of effectively prolonging the service life of the through ground wire in cooperation with the anticorrosive layer wrapped around the sheath.
Description
Technical field
The utility model belongs to a kind of railway grounding system technical field, relates to a kind of ground connection Through ground wire, relates in particular to a kind of railway signal ground connection Through ground wire.

Through ground wire is a kind of integrated ground line for railway signal system, is that electrical system keeps the consistent protective earth of operating potential, guarantees that the grounding safety of system equipment is reliable, eliminates between the distinct device because the current potential unsymmetrical current that potential difference causes.
Existing railway run-through ground line is comprised of pure copper stranded wire and the conductive high polymer sheath, the lead sheath that are coated on copper stranded conductor outside mostly, although lead sheath has good anti-corrosion property, but can cause serious pollution to surrounding enviroment, although and conductive high polymer sheath has good environmental protection characteristic, but do not have flame-retarding characteristic, simultaneously the earth resistance of conducting polymer composite is large, and the fault current earial drainage effect of Through ground wire is had certain influence.
The utility model content
The purpose that the utility model solves is to provide a kind of ground connection Through ground wire, and this ground wire has good fault current discharge capacity, good antiseptic fire-retardation effect, reliably useful life, high mechanical strength and cheap manufacturing cost.
The utility model is to be achieved through the following technical solutions:
A kind of ground connection Through ground wire comprises by multiple conducting wires and presses the stranded conductor that forms and the copper alloy sheath that is coated on the conductor outside that described copper alloy sheath is coated with anticorrosive coat.
The wire of described conductor adopts the metal or alloy material to make.
Described conductor presses stranded forming by the plain conductor more than seven or seven or alloy lead wire.
The copper alloy sheath is the hermetic type sheath that adopts copper alloy belt to make.
The hermetic type sheath adopts copper alloy belt to form after vertical wrap molding, welding, drawing, annealing, Passivation Treatment.
The thickness of described copper alloy sheath is 0.8mm～2.0mm.
Compared with prior art, the utlity model has following useful technique effect:
The utility model conductor adopt multiple conducting wires press stranded form can effectively increase conductor inner and with the radially contact area of copper alloy sheath, reduce the contact resistance of Through ground wire and copper alloy sheath, namely reduce the earth resistance of Through ground wire, strengthened the effect of Through ground wire fault current earial drainage.The copper alloy sheath has good corrosion-resistant, anti-oxidant and fire resistance simultaneously, cooperates the outer anticorrosive coat of sheath can effectively increase the useful life of Through ground wire.

Description of drawings
Fig. 1 is the structural representation in the utility model cross section.
Wherein: 1 is conductor; 2 is the copper alloy sheath; 3 is anticorrosive coat.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, ground connection Through ground wire of the present utility model, comprise that the thickness that the wire of being made by many metal or alloy materials presses with one heart the stranded conductor that forms 1 and closely is coated on conductor 1 outside is the copper alloy sheath 2 of 0.8mm～2.0mm, wherein, described conductor 1 and copper alloy sheath 2 close contacts, reduced the contact resistance of the two, described copper alloy sheath 2 is coated with anticorrosive coat 3, has prolonged the useful life of Through ground wire.Press behind the wire stranding that conductor 1 can be made by 7 metal or alloy materials and form.The wire that conductor adopts the metal or alloy material to make presses stranded forming, can effectively increase conductor inner and with the radially contact area of copper alloy sheath 2, reduce the contact resistance of Through ground wire and copper alloy sheath 2, namely reduce the earth resistance of Through ground wire, strengthened the effect of Through ground wire fault current earial drainage.Described copper alloy sheath 2 is the hermetic type sheaths that adopt the corrosion resistant copper alloy belt to form after vertical wrap molding, welding, drawing, annealing, Passivation Treatment, this copper alloy sheath 2 has good corrosion-resistant, anti-oxidation, fire-retardant, fire resistance and mechanical performance, coat anticorrosive coat in copper alloy sheath 2 outsides, prolonged the useful life of Through ground wire, nontoxic, harmless, can not cause environmental pollution.
The wire that conductor of the present utility model adopts the metal or alloy material to make presses stranded forming, can effectively increase conductor inner and with the radially contact area of sheath, reduce the contact resistance of Through ground wire and sheath, namely reduce the earth resistance of Through ground wire, strengthened the effect of Through ground wire fault current earial drainage.Copper alloy belt has good corrosion-resistant, anti-oxidant and fire resistance, can effectively increase the useful life of Through ground wire.Therefore this ground wire mechanical performance is good, is easy to lay, and can stand high vibration and stretching, and has the characteristics such as anticorrosion, fire-retardant, fire-resistant, waterproof, anti-oxidation, cheap manufacturing cost, long service life.
Above embodiment only is used for explanation the utility model, but not is used for limiting the utility model.
