Abstract
The utility model relates to a molded line stranded conductor for a cable, which comprises a plurality of conducting single lines. The plurality of conducting single lines are divided into a plurality of layers and wrap around a core line; furthermore, all conducting single lines are spirally stranded together; and the cross sections of the conducting single lines are in geometrical shapes which can be mutually spliced seamlessly into an approximate round. The single lines of the molded line stranded conductor for the cable are mutually connected in an embedding way when being stranded to form the firm and reliable stranded conductor so that the block coefficient of the conductor reaches 0.97. Under the same conductor cross section, the outside diameter of the conductor is decreased by 7-15% compared with that of a conventional round non-compacted conductor and is decreased by 3-6% compared with that of a compacted conductor; the materials for an insulating layer and a coating layer are saved greatly; the service life of the cable is improved; a point discharge phenomenon can not occur when the conductor is used in a middle-voltage cable and a high-voltage cable; furthermore, a compacting procedure is saved; the production efficiency of a stranded line is improved; simultaneously, the work hardening phenomenon of metal can not occur; all single lines can still maintain the characteristics before being stranded; and under the same cross section, the conductive property is better than that of the compacted conductor; and the bending property of the cable is good.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of cable molded lines stranded conductor.
Background technology
Cable generally is to be made of conductor, insulating barrier and serving, in order to improve the current capacity of cable, people adopt the sectional area that improves cable conductor usually, the method that improves the cable conductor sectional area mainly is to adopt many single lines to carry out stranded, yet this stranded conductor, at first, cause conductor diameter bigger, caused the rising of cost owing between its conductor layer and between each single line the space is arranged all; People dwindle conductor diameter in order to reduce void area, save the material of insulating barrier and serving, the general mode that adopts layering to press, yet for compact conductor, its amount of pressing is subjected to the restriction of metal processing molded lines, and its amount of pressing can not be excessive, as press excessive, occur fracture of wire easily,, then must weld in case fracture of wire occurs, cause that efficient is low, outward appearance is bad, so its activity coefficient is generally below 0.9; Secondly, conductor is a metal work hardening process pressing process, and conductor is after pressing, and conductor material hardens, and causes conductor intensity to become big, and electric conductivity descends, the bending property variation.Therefore, under the prerequisite that does not change the conductive characteristic of conductor own, reduce the space between the conductor single line, dwindle conductor diameter and save cable cost, improve the bending property of cable simultaneously, still having on the structure of cable conductor is worth improved place.
The utility model content
The purpose of this utility model is to provide a kind of deficiency, good bending property, softness that overcomes above-mentioned prior art, does not need to press, the activity coefficient height, can save the cable molded lines stranded conductor of cable cost.
The technical scheme that realizes the utility model purpose is: a kind of cable molded lines stranded conductor, have some conduction single lines, described some conduction single lines are divided into multilayer and are wrapped in around the heart yearn, and the single line that all conducts electricity revolves and twists together, and the cross sectional shape of conduction single line is for being spliced into mutually near circular geometry.
Above-mentioned cable molded lines stranded conductor respectively conduct electricity single line be copper aluminium matter or make based on the alloy material of copper aluminium, cross sectional shape is fan-shaped or trapezoidal or polygon or Z-shaped lead.
The heart yearn of above-mentioned cable molded lines stranded conductor is copper or aluminium matter or the cylindrical conductor that is spliced into based on cylindrical or some sector shaped conductors that the alloy material of copper aluminium is made.
Some conduction single lines of above-mentioned cable molded lines stranded conductor all twist together by a direction spiral.
Every layer on some conduction single lines of above-mentioned cable molded lines stranded conductor twist together by a direction spiral, and the hand of spiral is opposite between each layer.
The utlity model has following characteristics: it is that the shape of each single line of stranded conductor is stranded by circular single line that the utility model mainly improves, it is stranded to change various type single lines into, promptly all single lines are different molded lines, the cross sectional shape of each single line is fan-shaped or trapezoidal or polygon or Z-shaped lead, carry out stranded to it then, mutual embedding connection when each single line is stranded, form firm, firm stranded conductor, make the activity coefficient of conductor reach 0.97, under the same conductor cross section, conductor diameter dwindles 7～15% than conventional circular non-compact conductor, dwindles 3%～6% than the conductor diameter of pressing, and has saved insulating barrier and serving material greatly; The stranded conductor any surface finish, can not cause the conductive surface burr to dampen insulation because of pressing, there is not the gap between conductor simultaneously, guarantee that cable is in production and laid processes, after in a single day conductive surface runs into water, can not enter conductor inside, reach radially resistance effect of a conductor, the useful life of having improved cable, and the conductor outer surface is bright and clean closely, no burr is used in the medium and high voltage cable and can produce point discharge phenomenon, has reduced and has pressed operation, improve twisted wire production efficiency, metal work hardening phenomenon can not occur simultaneously, each single line still keeps stranded characteristic before substantially, under the same cross-sectional, electric conductivity is better than compact conductor, the cable good bending property.
