Summary of the invention

The purpose of this utility model is for deficiency of the prior art, and a kind of double sheathed cable is provided, and its objective is: the protection effect that improves cable.

For achieving the above object, the utility model by the following technical solutions: a kind of double sheathed cable, it includes power core and ground core, power core and ground core twisted synthesizing cable core, cable core is provided with inner sheath, reinforced layer, oversheath outward successively, wherein:

Described power core consists of power line core conductor and power line core insulation layer, and power line core conductor is by the stranded power line core conductor forming of copper conductor;

Described ground core consists of ground wire core conductor and ground wire core insulation layer, and ground wire core conductor is by the stranded ground wire core conductor forming of copper conductor;

Described reinforced layer is filament braid.

Further, described power line core conductor is by the 5th kind of stranded power line core conductor forming of soft copper conductor; Described ground wire core conductor is by the 5th kind of stranded ground wire core conductor forming of soft copper conductor.

Further, described inner sheath is the inner sheath that neoprene forms.

Further, described oversheath is the oversheath that neoprene forms.

Adopt the beneficial effect after technique scheme:

1, cable core structure is stable.Cable core stranding lay ratio is little, and the construction of cable is stable.Between inner/outer sheath, adopt filament braiding to strengthen, whole jacket structure is stable, and protective capacities is strong.

2, the 5th kind of stranded conductor forming of soft copper conductor, in the useful life of increase cable, makes cable soft.

3, neoprene forms inner sheath and oversheath, have the premium properties of high strength, fire-retardant, wear-resisting, waterproof.

In figure: 1, power core, 1-1, power line core conductor, 1-2, power line core insulation layer, 2, core, 2-1, ground wire core conductor, 2-2, ground wire core insulation layer, 3, cable core, 4, inner sheath, 5, reinforced layer, 6, oversheath.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Embodiment mono-

As shown in Figure 1, a double sheathed cable, its include power core 1, core 2, inner sheath 4, reinforced layer 5 and 6, three power cores 1 of oversheath and one ground core 2 be twisted into cable core 3, cable core 3 is outer establishes inner sheath 4, reinforced layer 5, oversheath 6 successively, wherein:

Power core 1 consists of power line core conductor 1-1 and power line core insulation layer 1-2, and power line core conductor 1-1 is by the stranded power line core conductor forming of copper conductor; Power line core conductor 1-1 is preferably by the 5th kind of stranded power line core conductor forming of soft copper conductor;

Ground core 2 consists of ground wire core conductor 2-1 and ground wire core insulation layer 2-2, and ground wire core conductor 2-1 is by the stranded ground wire core conductor forming of copper conductor; Ground wire core conductor 2-1 is preferably by the 5th kind of stranded ground wire core conductor forming of soft copper conductor;

Reinforced layer 5 is filament braids.

The inner sheath that the preferred neoprene of inner sheath 4 in above-mentioned cable or similar material form.The oversheath that the preferred neoprene of oversheath 6 in above-mentioned cable or similar material form.

Embodiment bis-

As shown in Figure 2, embodiment bis-is with the difference of embodiment mono-: cable core 3 is twisted into by three power cores 1 and three ground cores 2.So, outer inner sheath 4, reinforced layer 5, the oversheath 6 established successively of cable core 3.

In technical scheme specific implementation process, the number of power core 1 and ground core 2 can be definite according to actual needs, as: three power cores and two ground cores, above-mentioned power core and ground core twisted synthesizing cable core 3.

The utility model is not limited to above-described embodiment, and the technical scheme that all employings are equal to replacement or equivalence replacement formation all belongs to the claimed scope of the utility model.
