Abstract
The utility model discloses a power cable that performance is good, it includes the oversheath, set up in the inside triangle -shaped support of oversheath and locate the conductor of the three limit of triangle -shaped support department, the conductor includes conductor, shielding layer, insulating layer and fire -retardant layer by interior outside to in proper order, is the insulating filler who is made by water blocking material in the cavity between support and the oversheath, the conductor includes the columniform conductor, centers on the trapezoidal single line conductor of mutual matched with around the cable core. Every mutual overlap of wire in the trapezoidal single line conductor of this novel setting, every single line bottom are settled rather than adjacent unilinear top, trapezoidal wire compact structure, be difficult for loose, set up the support, relative position is more firm for the power cable three -phase, and sliding friction's phenomenon can not appear in contactless each other, having set up the insulating layer, can having prevented the burning on fire of oversheath and insulating layer, guaranteed personal safety, just the cushioning effect can also be played in fire -retardant layer, but protection of cables is not destroyed in the installation.
Description
Technical field
The utility model relates to a kind of threephase cable electric power of improvement.
Background technology
In conveying electrical travelling industry, power transmission cable application widely.General power cable has insulation property and certain resistance to corrosion, can effectively avoid phase fault and ground fault, be widely used in power distribution network.Existing three-phase electrical cable generally adopts the structure of coated insulation layer outside core, long-time use insulating barrier easily occurs aging, cause the decreasing insulating of cable, leak electricity, the phenomenon such as short circuit, useful life is short, and the wire of threephase cable is all cylindrical, between so each phase, also easily there is short circuit in easy sliding friction; Fire resistance is also not too qualified.
Utility model content
The technical problems to be solved in the utility model is to provide the better novel power cable of a kind of cable performance.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the power cable that serviceability is good, it is characterized in that: it comprises oversheath, is arranged at the triangular supports of oversheath inside and is located at the conductor at described triangular supports three limits place, described conductor comprises conductor, screen, insulating barrier and flame-retardant layer from inside to outside successively, the insulation filler for being made by material water-proof material in the cavity between described support and oversheath;
Described conductor comprises columniform conductor, be centered around the trapezoidal single line conductor of working in coordination around cable core.
Described triangular supports three limits are provided with shape and the supporting storage tank of conductor.
Described flame-retardant layer material is the mixing of Strong oxdiative aluminium, magnesium hydroxide or two kinds.
The beneficial effect adopting technique scheme to produce is:
1, be provided with every root wire in trapezoidal single line conductor mutually overlapping, bottom every root single line, be placed in the top being adjacent single line, during use, trapezoidal shape wired conductors compact conformation, wire is not easily loose;
2, the utility model is provided with support, and the A phase of power cable, B phase, C phase relative position are more firm, and do not contact each other, there will not be the phenomenon of sliding friction, and then there will not be short circuit phenomenon;
3, the utility model is provided with insulating barrier, can prevent the catching fire of oversheath and insulating barrier, ensure personal safety, and flame-retardant layer can also play cushioning effect, and cable can be protected not to be destroyed in installation process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, oversheath, 2, triangular supports, 3, insulating barrier, 4, conductor, 5, trapezoidal single line conductor, 6, screen, 7, flame-retardant layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See accompanying drawing 1, see accompanying drawing 1, the present embodiment comprises oversheath 1, is arranged at the triangular supports 2 of oversheath 1 inside and is located at the wire at described triangular supports 2 three limits place, described wire comprises conductor, screen 6, insulating barrier 3 and flame-retardant layer 7 from inside to outside successively, the insulation filler for being made by material water-proof material in the cavity between described triangular supports 2 and oversheath 1; Described screen 6 electromagnetic-field-shielded in cable, and can play certain ground protection effect.Described flame-retardant layer 6 can be non-combustible material in ignition temperature or close to endothermic decomposition under ignition temperature, the effective burning stoping cable.Described flame-retardant layer 7 material is the mixing of Strong oxdiative aluminium, magnesium hydroxide or two kinds.
Described wire comprises columniform conductor 4, be centered around the trapezoidal single line conductor 5 of working in coordination around conductor 4.Conductor 4 is arranged on bosom.
Described triangular supports 7 three limits are provided with the storage tank of shape and the supporting circular arc type of conductor, and conductor is positioned at this storage tank, can not contact, also would not occur the phenomenon of sliding friction between so each phase.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the invention, can realize in other embodiments.Therefore, the invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
