Abstract
The utility model relates to an improvement on a bundle assembled aerial cable, which is characterized in that a force bearing reinforcing core and power transmission conductor cores are separated into independent cores; the power transmission conductor cores and the force bearing core are arranged in a flower shape; and all wires are connected by connecting ribs. Not only are the advantages of an original parallel bunched cable kept, but also the force bearing core is separated from power transmission conductors, so that a tensile force is totally borne by the force bearing core, the cable has low aerial sag degree and large aerial span, the using amount of electric poles can be saved, and the erection cost and the cost of iron poles are reduced. Moreover, no electrochemical reaction is generated, electrochemical corrosion is avoided, a flower-shaped arranged section area is reduced, and the bundle assembled aerial cable is difficult to accumulate snow, is more reliable to operate and is safer to use. The force bearing core adopts a stranded steel wire; and under the condition that the bundle assembled aerial cable is covered with ice and snow, when the bundle assembled aerial cable is powered on, the ice and the snow can melt. The bundle assembled aerial cable can also be used as a ground wire. The step of separately arranging a ground wire core can be saved. Therefore, the separate force bearing steel core achieves the effect of integrating three functions (the bearing of the tensile force, the ground wire and the melting of the ice and the snow) into one cable.
Description
Technical field
Utility model is the improvement to bundle assembled aerial cable, relates in particular to a kind ofly can reduce sag and can omit ground wire and from the bundle assembled aerial cable of ice-melt.
Background technology,
Parallel bunched aerial insulated cable, it is a kind of economized form of realizing the overhead wire insulating, be mainly used in city power supply grid or open-air built on stilts electric line, it is that each insulated wire cores is adopted the mode that is arranged in parallel, between core, adopt the band muscle to connect, for example Chinese patent CN101494101A is parallel with many cables and extrudes simultaneously alternately, is connected by dowel each other.In order to improve tensile strength, also have one and thoroughly do away with the edge core or thoroughly do away with the inner stranded strengthening core of edge core more, for example to have a core at least be aluminium alloy core and/or steel strand wire core and/or steel reinforced aluminium conductor core to Chinese patent CN1447345.This kind will be born the carrier cable (steel core) of pulling force and mix with single line core wherein, load core (for example steel strand wire) and aluminium conductor are born pulling force simultaneously, because the coefficient of linear expansion of aluminium conductor is much larger than steel strand wire, when built on stilts the laying, need determine by the aluminium conductor coefficient of linear expansion, make that like this aerial cable sag is bigger, span can not be excessive, especially behind heating power, strengthened the sag of overhead wire especially; Secondly, steel aluminium mixes, and there are potential difference in invar, aluminium, not only are easy to generate eddy current loss, and cause electrochemical corrosion, have reduced the corrosion resistance of cable; Besides, parallel word order structure, developed area is easy to generate accumulated snow greatly, and is not easy to remove after producing accumulated snow, easily causes disaster, and therefore still having is worth improved place.。
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, and a kind of low arc drop is provided, and can omit ground wire, and anti-accumulated snow is good, and can be from the bunched aerial lead of ice-melt.
The utility model purpose realizes, the main improvement is to change bunched cable version, and the load core is separated with the power transmission conductor core independently becomes a core, and makes each power transmission conductor core and load core be colored shape arrangement, thereby overcome the deficiencies in the prior art, realize the utility model purpose.Specifically, the utility model bundle assembled aerial cable comprises that interconnect boundling thoroughly does away with edge core and load strengthening core more, and it is characterized in that the load strengthening core separates with the power transmission conductor core independently becomes a core, and make each power transmission conductor core and load core be colored shape arrangement, there is dowel to connect between each line.
The said load strengthening core of utility model, same prior art, can be cable industry with various high tensile ropes, rope, such as but not limited to steel strand wire, aluminum-cladding stranded wire, aluminium alloy stranded conductor, fibre resin composite core, other organic or other composite material high strength ropes etc.
Power transmission conductor core and load core are colored shape to be arranged, and its main purpose is to adopt this arrangement mode, can reduce the bunched cable cross section, reduces the anti-accumulated snow in cross section thereby reach.The arrangement of flower shape is the colored shape structure that adopts non-in-line to arrange, and for example transmission pressure and order wire (if there is) are distributed in one side or its equidistant arrangement of load core on every side, and colored in detail shape can be with reference to the accompanying drawings.
The utility model bundle assembled aerial cable, with respect to prior art, owing to adopt and to make somebody a mere figurehead the load core and separate with the power transmission conductor core and independently become a core, and make each core and load core be the colored shape arrangement architecture of a non-word, not only kept the advantage of former parallel bunched cable, and separate with power transmission conductor because of the load core, pulling force has the load core to bear fully, and the built on stilts degree of speeding of cable is little, and built on stilts span is big, can save the electric pole consumption, reduce and set up cost and iron cost.And do not have electrochemical reaction and produce, avoided electrochemical corrosion, flower shape is arranged sectional area and is reduced and be difficult for accumulated snow, moves more reliably, uses safer.Usually the load core adopts stranded steel wire in addition, and load steel core no current passes through when circuit normally moves, and therefore can not generate heat, and sag can not increase substantially; Having icing snow situation to descend, can also utilize the energising of load steel core, its big relatively resistance produces heat energy and avenges from ice-melt, and becomes the ice-melt lead; The load steel core is independent, can also use as ground wire, can omit and set up the ground core separately, and the load steel core reaches a line three usefulness (bearing pulling force, ground wire, ice-melt snow) separately thus.Insulation of load core sheath and phase line and fiber cable jacket (if there is) are extruded simultaneously separately, do not increase technology in addition.In the bigger circuit of span, in order to improve pulling force, as long as strengthen strengthening core area or intensity, and can be not stranded, can increase the outside diameter of cable greatly after increasing area, thereby cause increasing the insulating material consumption as mixing.
Below in conjunction with several specific embodiments; utility model essence is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the total technical scheme of utility model is limited; some are In the view of the technical staff; the unsubstantiality that does not depart from the utility model design increases and/or change; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.
