Background technology
Carrier cable is the auxiliary products of electric railway suspension contact wire, is mainly hung carrier cable by dropper
Come.Carrier cable can also carry a constant current to reduce impedance of traction electric network, reduce voltage loss and energy consumption.Carrier cable can according to material
It is divided into copper carrier cable, steel carrier cable, aluminium Baogang carrier cable.Steel carrier cable need to take anti-corrosion measure, and carrier cable is in electrified iron
In the contact net circuit of road, carry transmission of electricity and hang the important conducting wire of locomotive slideway line double action.Due to the special work of railway
Industry conditions and environment is also very high to carrier cable performance requirement, it is desirable that carrier cable is conductive strong, by flowing.There is certain lead
Electric current capacity, moreover it is possible under different regions, four seasons temperature, the variation of various weather conditions, can guarantee normal good power transmission；It will
It is corrosion-resistant, long lifespan.Can bear various atmospheric environment factories, it is existing match, the chemical contaminations corrosion such as alkali, salt, sulphur；Want intensity
It is high, from heavy and light.Deform that small, arc sag is uniform to ensure carrier cable after erection, can bear locomotive by the vibration of transmission and wind,
The natural environments external force such as ice, rain, snow load acts on.
Copper carrier cable conducts electricity very well, and can do one of channel of traction current and contact line parallel operation, reduce crushing and
Energy consumption, and corrosion resistance is high.But copper carrier cable consumption copper is more, and cost is high and mechanical strength is low, it is impossible to larger tension is born,
Sag changes also greatly during temperature change.
Steel carrier cable is made of zinc-plated barium twisted wire, and intensity is high, tension is big, and installation sag is small and sag variation is also small, both
Save non-ferrous metal low cost again.But its shortcoming is big for resistance, and electric conductivity is poor, generally non-current carrying catenary.Steel carrier cable
Not corrosion-resistant, when use, will also use anti-corrosion measure.
Aluminium Baogang carrier cable is that aluminium covers steel wire and aluminum steel is hinged to form, and the steel core part in steel wire is mainly covered with aluminium and bears to open
Power, alclad and aluminum steel current-carrying, conduct electricity very well, and mechanical strength and corrosion resistance are preferable.
Utility model content
The purpose of this utility model is to provide a kind of overcome the deficiencies in the prior art, tension simple in structure, easy to use
A kind of highly conductive carrier cable that intensity is high, conductivity is good.
To achieve these goals, the technological means that the utility model is taken is：
A kind of highly conductive carrier cable, matrix and external twisted wire, twisted wire including being located at center are spirally wound on matrix
Outside, key are：Affiliated matrix includes center conductor and center protective layer, and center conductor is four copper-silver alloy conducting wire spiral shells
Rotation is wound, and center protective layer is semi-conductive tape, and twisted wire includes at least two layers of twisted wire layer, set between twisted wire layer and twisted wire layer
Twisted wire protective layer is equipped with, twisted wire protective layer fills layer for copper magnesium alloy pipe, and is twined in twisted wire layer for more copper magnesium alloy conducting wire spirals
Around formation, the spiral winding direction between twisted wire layer and twisted wire layer, between twisted wire layer and center conductor is reversed.
The outermost of twisted wire layer is provided with exterior protection layer.
The exterior protection layer includes the scribbled organization level and waterproof layer arranged successively from inside to outside.
The waterproof layer is polyurethane water-proof paint layer.
The longitudinal section of single copper magnesium alloy conducting wire in the twisted wire layer is arch
The beneficial effects of the utility model are：The utility model use Kufil centered on conducting wire, conductivity with
The conductivity of fine copper monofilament is close, but tensile strength is apparently higher than fine copper monofilament, and four Kufil spiral windings are into one
Step increases its tensile strength, and center protective layer, twisted wire protective layer and exterior protection layer more increase its tensile strength and guarantor
Whole electric conductivity is demonstrate,proved.
