Background technology
The conventional carrier cable of electric railway is usually the copper or copper-alloy stranded conductor of nude, is held under the condition of high temperature of operation
Power rope surface is easily oxidized.In train in/out station, the drastically change of speed can cause between carrier cable, dropper, contact line
Tension force is unstable, or even has electric spark appearance, causes potential safety hazard.
The content of the invention
The purpose of this utility model is in the same of increase structural stability the problem of presence for prior art there is provided a kind of
When can prevent electric spark with the carrier cable for the tape insulation for reducing potential safety hazard.
The purpose of this utility model is solved by the following technical programs：
A kind of carrier cable of tape insulation, including copper-magnesium alloy strand core, it is characterised in that：The copper-magnesium alloy strand line
The outside of core is surrounded with high intensity semi-conductive tape, covered with insulating barrier successively, and the thickness of insulating barrier is copper-magnesium alloy strand line
The 15%-20% of core external diameter.
The structure of the copper-magnesium alloy strand core is from inside to outside copper magnesium alloy monofilament, m root copper magnesium alloys monofilament,
2m root copper magnesium alloys monofilament, 3m root copper magnesium alloy monofilament, wherein integer m are 4~8.
The strand of the adjacent layer of the copper-magnesium alloy strand core to opposite and copper-magnesium alloy strand core it is outermost twist to
For S to.
Content of magnesium 0.4%~0.5% in the copper magnesium alloy monofilament of the copper-magnesium alloy strand core, and copper magnesium alloy monofilament
Tensile strength is more than 700MPa, conductance and is more than 60%IACS.
The thickness of the high intensity semi-conductive tape is not less than 1mm.
The rate of putting up of the high intensity semi-conductive tape is 20%~30%.
The utility model has the following advantages compared with prior art：
The utility model by setting high intensity semi-conductive tape and insulating barrier to be protected outside copper-magnesium alloy strand core,
Prevent air oxidation, and the monofilament of copper-magnesium alloy strand core can be prevented to produce displacement under stringing tension force, add structure
Stability；Insulating barrier can prevent carrier cable from producing electric spark under various fortuitous events simultaneously, reduce potential safety hazard and line
The possibility of material scaling loss.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the carrier cable of tape insulation of the present utility model.
Wherein：1-copper-magnesium alloy strand core；2-high intensity semi-conductive tape；3-insulating barrier.
Embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1：A kind of carrier cable of tape insulation, including copper-magnesium alloy strand core 1, the copper-magnesium alloy strand core
Content of magnesium 0.4%~0.5% in 1 copper magnesium alloy monofilament, and the tensile strength of copper magnesium alloy monofilament is big more than 700MPa, conductance
In 60%IACS；It is surrounded with high intensity semi-conductive tape 2 successively in the outside of copper-magnesium alloy strand core 1, covered with insulating barrier 3, it is high
It is 20%~30% that the thickness of intensity semi-conductive tape 2, which is not less than 1mm and puts up rate, and the thickness of insulating barrier 3 is copper-magnesium alloy strand line
The 15%-20% of the external diameter of core 1.In said structure, the structure of copper-magnesium alloy strand core 1 is from inside to outside a copper magnesium alloy list
Silk, m root copper magnesium alloys monofilament, 2m root copper magnesium alloys monofilament, 3m root copper magnesium alloy monofilament, wherein integer m are 4~8；Copper magnesium alloy
The strand of the adjacent layer of twisted wire core 1 to opposite and copper-magnesium alloy strand core 1 it is outermost twist to for S to.
As shown in figure 1, the copper-magnesium alloy strand core 1 of the carrier cable for the tape insulation that the utility model is provided is four layers of knot
Structure, wherein m are the four-layer structure that 6, i.e. copper-magnesium alloy strand core 1 are 1+6+12+18.
The utility model in the outer setting high intensity semi-conductive tape 2 of copper-magnesium alloy strand core 1 and insulating barrier 3 by being protected
Shield, has prevented air oxidation, and the monofilament of copper-magnesium alloy strand core 1 can be prevented to produce displacement under stringing tension force, adds
The stability of structure；Insulating barrier 3 can prevent carrier cable from producing electric spark under various fortuitous events simultaneously, reduce potential safety hazard
With the possibility of wire rod scaling loss.
Above example is only explanation technological thought of the present utility model, it is impossible to limit protection model of the present utility model with this
Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical scheme each falls within this reality
