Description

Novel power cable

Technical Field

The utility model relates to a novel power cable.

Background

The power cable should have a function of using to transmit a large capacity of electric energy safely and reliably, whereby performance requirements for the power cable are: good conductive performance, excellent electrical insulation performance, heat balance under the working state and large-capacity electric energy transmission. However, the conventional power cable cannot resist the external impact and extrusion, and unless a special matching device is added, the special assembling device is complex to manufacture and high in cost.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the defects in the prior art are overcome, and the novel power cable can quickly buffer external impact and extrusion.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel power cable, includes the cable core of 1 at least sinle silk, the cable core includes the conductor and wraps up the insulating layer of conductor, is provided with a buffer tube at least between per two cable cores, and buffer tube and cable core wrap up by band and form a cylinder, have set gradually shielding layer, inner liner, armor, sheath and protective layer outside this cylinder.

In order to guarantee the impact resistance and the extrusion resistance of the cable, the buffer tube is further defined to be a hollow elastic tube.

Further defined, the cable core is provided with three and the buffer tubes are provided with four.

In order to further increase the impact resistance and the extrusion resistance of the cable, an outer buffer tube is arranged between the inner liner layer and the armor layer, and the outer buffer tubes are uniformly distributed along the periphery of the inner liner layer.

In order to ensure that the cable can normally work in a dangerous environment, the armor layer is further limited to be armored by steel belts.

The utility model has the advantages that: the utility model discloses a novel power cable, processing technology is simple, and is with low costs, can effectively improve the anti impact and anti extrusion performance of cable, has strengthened the factor of safety that the cable can normally work in hazardous environment.

Drawings

The present invention will be further described with reference to the accompanying drawings and embodiments.

Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention.

Fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.

Fig. 3 is a schematic structural diagram of embodiment 3 of the present invention.

In the figure: 1. the cable comprises a cable core, 2 parts of buffer tubes, 2' parts of outer buffer tubes, 3 parts of wrapping tapes, 4 parts of shielding layers, 5 parts of lining layers, 6 parts of armor layers, 7 parts of sheaths, 8 parts of protective layers, 1-1 parts of conductors and 1-2 parts of insulating layers.

Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

Example 1

As shown in fig. 1, the novel power cable of this embodiment includes a cable core 1 with three cable cores and four buffer tubes 2, the cable core 1 includes conductors 1-1 and insulating layers 1-2 wrapping the conductors 1-1, at least one buffer tube 2 is disposed between every two cable cores 1, the buffer tube 2 and the cable cores 1 are wrapped by a wrapping tape 3 to form a cylinder, and a shielding layer 4, an inner liner layer 5, an armor layer 6, a sheath 7 and a protective layer 8 are sequentially disposed outside the cylinder.

In the present embodiment, the buffer tube 2 is embodied as a hollow elastic tube. The armor layer 6 adopts steel tape armor.

Example 2

As shown in fig. 2, the difference from embodiment 1 is that: an outer buffer tube 2 'is arranged between the lining layer 5 and the armor layer 6, and the outer buffer tubes 2' are uniformly distributed along the periphery of the lining layer 5.

Example 3

As shown in fig. 2, the difference from embodiment 1 is that: only include the cable core 1 of three sinle silks, do not have buffer tube 2, be provided with outer buffer tube 2 'between inner liner 5 and armor 6, outer buffer tube 2' is along 5 periphery evenly distributed of inner liner.

Compared with the common power cable, the novel power cable of the two embodiments has the advantages of simple processing technology and greatly improved damage resistance, and can be applied to common occasions and specific occasions with damage risks.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable people skilled in the art to understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
