Description
Technical field
The utility model relates to technical field of electric wires and cables, more particularly to a kind of electric railway copper-alloy stranded conductor.
Background technique
Copper wire is widely used in the carrier cable of aerial condutor, electric railway and urban rail transit contact network, pile
The lightning conducter of object, electrical equipment ground line etc., but since copper wire is too soft so that it is easily deformed, therefore generally twisted using hard copper
Line or copper-alloy stranded conductor, but hard drawn copper strand wire or copper-alloy stranded conductor at present is on the high side, so that at high cost.Along with science and technology
Development, copper covered steel wire generate.Copper covered steel wire is pair for being integrated the high strength bond of the good electric conductivity of copper, corrosion resistance and steel
Metallic composite.In use, often encountering such situation in power engineering: when selecting thinner copper clad steel single line,
It is poor that current-carrying capacity can not meet the performances such as requirement or bearing capacity, fatigue strength；It is when selecting thicker copper clad steel single line, then soft
It is soft poor, it is difficult to which that bending deformation is not easy to cable processing and uses.
Utility model content
The purpose of the utility model is to provide a kind of electric railway copper-alloy stranded conductor, whole rigidity and strong is improved
Degree, ensure that whole fatigue strength.
To achieve the above object, the utility model provides a kind of electric railway copper-alloy stranded conductor, including ontology, institute
Stating ontology includes center line layer and twisted wire outer layer, and the twisted wire outer layer is located on the outside of the center line layer, the center line layer
Cross section is circle, and the section of the twisted wire outer layer is circular ring structure；
The center line layer includes one and is located at the hard single line of center and the hard single line week around center
The hard single line of the six roots of sensation concentric stranding enclosed, six groups of copper alloys strand that the twisted wire outer layer is included with the center line layer concentric stranding
Line, the copper-alloy stranded conductor include one and are located at the copper alloy single line of center and the copper alloy single line week around center
The six roots of sensation copper alloy single line enclosed.
Preferably, the diameter of the copper-alloy stranded conductor is identical, and the copper alloy single line is the identical copper wire of diameter, described hard
Matter single line is the identical stainless steel single line of diameter.
Preferably, the rupture pull force of the ontology is not less than 8.5KN.
Therefore, the electric railway copper-alloy stranded conductor of the utility model using the above structure, improve whole rigidity and
Intensity ensure that whole fatigue strength.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model electric railway copper-alloy stranded conductor embodiment；
Wherein: 1, center line layer；2, twisted wire outer layer；3, hard single line；4, copper-alloy stranded conductor；5, copper alloy single line.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Fig. 1 is the schematic diagram of the utility model electric railway copper-alloy stranded conductor embodiment, as shown, a kind of electrical
Change railway copper-alloy stranded conductor, including ontology, the rupture pull force of ontology is not less than 8.5KN.The rupture pull force of ontology is much larger than existing
There is standard to be not less than the requirement of 5.67KN, intensity obviously increases.
Ontology includes center line layer 1 and twisted wire outer layer 2, and twisted wire outer layer 2 is located at the outside of center line layer 1.Center line layer 1
Cross section is circle, and the section of twisted wire outer layer 2 is circular ring structure.Twisted wire outer layer 2 carries out same using the center of circle of center line layer 1 as the center of circle
The heart is twisted, six groups of copper-alloy stranded conductors 4 that twisted wire outer layer 2 is included with 1 concentric stranding of center line layer.Copper-alloy stranded conductor 4 and center line layer 1
Structure it is consistent, and concentric coiling is carried out with center line layer 1, while guaranteeing volume fatigue strength, improve whole rigidity and
Intensity.
Center line layer 1 includes one and is located at the hard single line 3 of center and around the hard single line 3 of center
Six roots of sensation concentric stranding hard single line 3, center line layer 1 be twisted wire outer layer 2 enough intensity is provided.Hard single line 3 is diameter
Identical stainless steel single line.
Copper-alloy stranded conductor 4 includes one and is located at the copper alloy single line 5 of center and the copper alloy list around center
Six roots of sensation copper alloy single line 5 around line 5.The diameter of copper-alloy stranded conductor 4 is identical, and copper alloy single line 5 is the identical copper wire of diameter.Copper
The surrounding for making copper-alloy stranded conductor 4 closely be centered around center line layer 1 is arranged in the structure and model of alloy twisted wire 4 and center line layer 1.
Therefore, the electric railway copper-alloy stranded conductor of the utility model using the above structure, improve whole rigidity and
Intensity ensure that whole fatigue strength.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model rather than limit it
System, although the utility model has been described in detail with reference to the preferred embodiment, those skilled in the art should manage
Solution: it still can be with the technical solution of the present invention is modified or equivalently replaced, and these are modified or equally replace
Changing also cannot make modified technical solution be detached from the spirit and scope of the technical scheme of the present invention.
