Description
Technical field
The utility model relates to power transmission device technical field, especially a kind of power cable.
Background technology
At present, in the actual application such as power distribution network, power cable scratch in use, broken skin are even very general by phenomenons such as mouse bite broken; Simultaneously, the problems such as existing power cable also exists power delivery capabilities difference, useful life is short, tensile resistance is weak, built-in electrical insulation and exterior insulation (especially multicore cable) weak effect, production cost are high, thus, cause existing power cable to there is very large potential safety hazard and also easily cause great economic loss.
Therefore, be necessary to propose improvement project to existing power cable.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide the power cable that a kind of structure is simple, with low cost, insulation effect is good, tensile resistance is strong.
To achieve these goals, the utility model adopts following technical scheme:
A kind of power cable, it comprises cable body, described cable body comprises some cable cores, cable core described in every root is all wrapped in an insulation lobe, the cross section of the structure of the assembled rear formation of the lobe that insulate described in several is disc, a Mosaic face of described insulation lobe offers on tongue-and-groove, another Mosaic face and is provided with tenon, between adjacent two described insulation lobes by tongue-and-groove chimeric with the contraposition of tenon carry out mutually assembled; Described cable body is wrapped in external protection.
Preferably, the material of described insulation lobe is tetrafluoroethene-hexafluoroethylene polymer.
Preferably, described cable core comprises the body twisted by stranded copper wire line, aluminium wire line or steel wire wire harness, and described body is wrapped in screen.
Preferably, be also provided with flame-retardant layer between described body and screen, described flame-retardant layer is made up of magnesium oxide mineral powder.
Preferably, be also provided with water blocking layer between described external protection and cable body, described water blocking layer is ointment.
Preferably, described external protection comprises the sheath, armour and the outer jacket that set gradually from the inside to the outside, and described sheath and outer jacket are polyvinyl chloride.
Owing to have employed such scheme, separate between each cable core of the present utility model, complete construction of cable body is spliced to form by utilizing the contraposition of tongue-and-groove and tenon, it is beneficial to the assembling effect, the reduction production cost that improve cable, ensure that the insulating properties between cable core, and then improve the transmittability of cable; Meanwhile, utilization insulation lobe can avoid the mutual extruding between cable core, is conducive to the stretch-proof and the bend resistance performance that improve cable; Its structure is simple, has very strong practicality and market popularization value.
Accompanying drawing explanation
Fig. 1 is the structural section schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the power cable of the present embodiment, it comprises cable body and is wrapped in the external external protection of cable; Wherein, cable body comprises some cable cores, every root cable core is all wrapped in an insulation lobe 1 be made up of tetrafluoroethene-hexafluoroethylene polymerizable material, the cross section of assembled rear the formed structure of several insulation lobes 1 is disc, a Mosaic face of each insulation lobe 1 all offers at least one tongue-and-groove, another Mosaic face and be provided with the tenon 2 chimeric with tongue-and-groove contraposition, so, between adjacent two insulation lobes 1 by tongue-and-groove chimeric with the contraposition of tenon 2 carry out mutually assembled, thus the construction of cable body that formation one is complete; For the effect of the present embodiment can be described more clearly, with cable body, there are three cable cores and be described.Pass through said structure, the power cable of the present embodiment then has many cable cores, separate between each cable core, complete construction of cable body is spliced to form by utilizing the contraposition of tongue-and-groove and tenon 2, be beneficial to the assembling effect, the reduction production cost that improve cable, ensure that the insulating properties between cable core, and then improve the transmittability of cable; Meanwhile, utilization insulation lobe 1 can avoid the mutual extruding between cable core, is conducive to the stretch-proof and the bend resistance performance that improve cable.
For expanding the scope of application of the cable of the present embodiment, the cable core of the present embodiment comprises the body 3 twisted by stranded copper wire line, aluminium wire line or steel wire wire harness and the screen 4 be wrapped in outside body 3.For improving the fire resistance of cable, can arrange flame-retardant layer 5 between body 3 and screen 4, flame-retardant layer 5 can be made up of magnesium oxide mineral powder.And be strengthen the water resistance of cable, can between external protection and cable body (namely between external protection and insulation lobe 1) be also provided with water blocking layer 6, the water blocking layer 6 of the present embodiment preferably material is ointment.In addition, for optimizing the structural behaviour of the power cable of the present embodiment further, strengthen its result of use, external protection comprises the sheath 7, armour 8 and the outer jacket 9 that set gradually from the inside to the outside, and wherein, sheath 7 and outer jacket 9 all can polyvinyl chloride.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
