Abstract
The utility model relates to an improvement of a compound cable with a control wire-core and a power wire-core, which is characterized in that: a neutral wire-core and a ground wire-core are divided into a plurality of single-line conductor, and each neutral wire-core and control wire-core are extruded with a insulator, the neutral wire-core and the ground wire-core form an arc shaped segment respectively, and are concentrically and uniformly distributed on a same circle out of the phase wire-core with the control wire-core. The utility model has the advantages that: the assignment of the wire-core is more reasonable; the structure is more compact; the outer diameter is small; the occupied space is small; the spherical degree and the stability are better; the cable is unlikely to loose or deviate during the extrusion and construction process; the filling materials and the belting are unneeded; so the consumption of the materials is reduced, the weight of the cable is lightened; meanwhile the length of the wire-core and the material waste are not increased due to the intertwisting structure and the electric energy loss is reduced.
Description
Technical field
Utility model is about the improvement to band control core and power core composite cable, relates in particular to a kind of concentric composite construction of more compact structure.
Background technology
In a lot of occasions, require also control cable need be set simultaneously at transferring electric power, people have developed the composite cable of band control core for this reason.
The composite cable that Chinese patent 01253981.3 disclosed power and control line merge, its structure is: three-phase power and control core add the stranded stranding of insulation and shielding back respectively, and concentric conductor is arranged outward.The deficiency of this structural cable is: four-core is stranded, core is arranged compact inadequately, core poor stability not only, roundness is poor, extrude and process such as construction in loose easily, and scurry the position easily, and it is stranded together to need to add packing material, reach band and tighten, material usage is big, has increased cable weight and cost.Secondly, this structure makes that also the outside diameter of cable is bigger, and especially big specification cable, big external diameter have not only increased manufacturing, transportation difficulty, and takies that to lay the space big.Besides, lay configuration also makes actual core length increase, waste material, and cable cost increases.
Chinese patent 01244628.9 disclosed dynamic Control comprehensive cable, its structure is: three thoroughly do away with the stranded composition power of edge power core cable core, the control core is evenly distributed on around the power cable with one heart, every with screen, controls core and is surrounded with separator outward more between the two.Though this structure has effectively reduced the outside diameter of cable, control core core number more after a little while, periphery control core is arranged difficulty, and can cause loosely organized.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of not only simultaneously transferring electric power and control signal are provided, and core arrangement compactness, and roundness is good, be difficult for loose, the composite cable of the band control core that external diameter is little.
The utility model purpose realizes, main improve be with neutral core, core, control core be arranged in the outer same circumference of phase core together.Specifically, the composite cable of utility model band control core, comprise phase core, neutral core, core, control core and oversheath, it is characterized in that said neutral core, core be divided into some single conductor, and each neutral core and control core are extruded with insulation at least, neutral line core conductor respectively becomes a segmental arc with the ground wire core conductor, with the concentric together outer same circumference of core mutually that is distributed on of control core.
The said phase core of utility model can be the single-phase core of extruded insulation, and for example single-phase insulation circle core also can be the three-phase core, as three stranded fan-shaped phase cores that respectively are extruded with insulation.
Control core position on circumference better is arranged on core both sides, ground and is advisable.For minimizing is subjected to Electromagnetic Interference, the control line core insulation is equipped with shielding outward more fortunately, for example metal wire knitted shielding.
Be convenient and make, by the neutral core of cable design, the core cross section, it is divided into some filled circles conductors, be to save cable cost, the ground core can directly adopt bare conductor, promptly neutral core is the filled circles conductor that extrudes insulation; The ground core is solid naked round conductor, and the control core better adopts the stranded flexible conductor of extruded insulation.Neutral core, core filled circles conductor diameter and radical determine, better be that arrangement can be abound with phase core excircle continuously after making it to add extruded insulation and all control cores.
In order effectively to discern three kinds of cores, can be distinguished by extruding the different insulative color.
To form the cable roundness good in order to make, Stability Analysis of Structures, the neutral core external diameter of each behind the said extruded insulation of utility model, control core, better identical with various places core external diameter.And each neutral core, the core external diameter identical, if having many control cores, can also be divided into earlier some groups stranded, and make it the neutral as far as possible core of external diameter, core identical.
In addition,, can also be laid with tear-strap, realize tearing of cable socket sheath peeled off by drawing back tear-strap in the cable jacket inboard for making things convenient for peeling off of cable connection middle-end end protective cover.
The composite cable of utility model band control core, can for phase line core, neutral core, the core cross-sectional sizes equate; Also can equate that core cross section, ground is than minor structure for phase line core, neutral core cross-sectional sizes; Can also be that the phase core is bigger, neutral core, the core cross section than minor structure.According to neutral core, core total cross section separately, arrange diameter by mentioned above principle design concentric circumferences.
The composite cable of utility model band control core and since adopt will control core, neutral core, core, concentric arrangement is same circle configurations outside cable core, it is more reasonable to make each core arrange, structure is more compact, external diameter is little, takies that to lay the space little; Secondly, this structural cable roundness, stability better, extrude and work progress in can not occur loose, scurry a phenomenon, do not need to use packing material and band yet, reduced the consumption of material, alleviated cable weight; Can the length of core be increased simultaneously yet, increase waste of material, and also can reduce electric energy loss because of adopting lay configuration.
Below in conjunction with the Three Represents embodiment, further specify the utility model structure.
