Description

A kind of light power cable

Technical field

This utility model relates to electric wire field, more specifically, it relates to a kind of light power cable.

Background technology

Very extensive that power cable is applied in power transmission, and power cable needs to lay at a distance, the power cable being presently required laying is wound on winding bucket, such as nonhalogenated flame resistant cable (application number: 200480022095.1), and the situations such as displacement are produced in order to avoid inner core, interstitial wire can be filled up between current power cable inner core and protection set, (1) cause that cable weight is bigger, and owing to bigger power cable is wound on together, what after causing winding bucket to wind one group of power cable, total weight causing greatly very carried very is heavy, (2) fill completely that cable elasticity buffer capacity is more weak, and be not easy to produce bending, it is not easy to lay.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of lighter in weight, consequently facilitating the light power cable of carrying.

For achieving the above object; this utility model provides following technical scheme: a kind of light power cable; including inner core, protection set; described multiply inner core is arranged in protection set; described inner core includes conductive core, internal layer protective layer from the inside to the outside successively; between described protection set and inner core, gap location is provided with buffer fillings layer, and described buffer fillings layer includes some interstitial wires, some inflation filling tapes, and axially arranged in described inflation filling tape have several to fill air bag.

This utility model is further arranged to: described filling air bag is spherical.

This utility model is further arranged to: described protection set includes tensile layer, wearing course from the inside to the outside successively, is provided with some inflation buffer strips between described tensile layer and wearing course, and axially arranged in described inflation buffer strip have several buffer air bags.

This utility model is further arranged to: described buffer air bag is ellipse.

In sum, this utility model has the advantages that multiply inner core is by protecting set parcel to become a power cable completely, inflation filling tape is filled on gap bigger between inner core and protection set, interstitial wire is filled on gap less between inner core and protection set, so that the gap that inner core and protection are overlapped is completely filled with, and due in inflation filling tape axially arranged several fill air bags, thus filling inflated body in air bag, thus filling air bag weight very light, so that whole piece inflation filling tape is lighter, thus being effectively reduced the weight of whole piece power cable, thus the quality after power cable winds also effectively alleviates, consequently facilitating the winding bucket after one group of power cable of winding is easy to carrying, and owing to being provided that independent filling air bag in inflation filling tape, and filling air bag has good elasticity, thus improve the effect of buffering, and be also easily deformed when bending, consequently facilitating the laying of power cable.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

As shown in Figure of description 1,2; a kind of light power cable; including inner core 1, protection set 3; described multiply inner core 1 is arranged in protection set 3; described inner core 1 includes conductive core 11, internal layer protective layer 12 from the inside to the outside successively; between described protection set 3 and inner core 1, gap location is provided with buffer fillings layer 2, and described buffer fillings layer 2 includes some interstitial wires 23, some inflation filling tapes 21, and axially arranged in described inflation filling tape 21 have several to fill air bag 22.

Such as Figure of description 1, shown in 2, multiply inner core 1 becomes a power cable completely by protecting set 3 parcel, inflation filling tape 21 is filled on gap bigger between inner core 1 and protection set 3, interstitial wire 23 is filled on gap less between inner core 1 and protection set 3, so that the gap that inner core 1 and protection overlap 3 is completely filled with, and due in inflation filling tape 21 axially arranged several fill air bags 22, thus filling inflated body in air bag 22, thus filling air bag 22 weight very light, so that whole piece inflation filling tape 21 is lighter, thus being effectively reduced the weight of whole piece power cable, thus the quality after power cable winds also effectively alleviates, consequently facilitating the winding bucket after one group of power cable of winding is easy to carrying, and owing to being provided that independent filling air bag 22 in inflation filling tape 21, and filling air bag 22 has good elasticity, thus improve the effect of buffering, and be also easily deformed when bending, consequently facilitating the laying of power cable.

As shown in Figure of description 1,2, described filling air bag 22 is spherical, it is spherical owing to filling air bag 22, thus the power that filling air bag 22 is squeezed when power cable bends can be disperseed everywhere, thus filling air bag 22 will not produce bigger deformation, but to deformation place two side shifting, it is damaged from thus fill air bag 22 when power cable produces significantly bending, and filling air bag 22 is restored by elastic effect after power cable restores, thus effectively raising service life.

Such as Figure of description 1, shown in 2, described protection set 3 includes tensile layer 31 from the inside to the outside successively, wearing course 32, some inflation buffer strips 33 it are provided with between described tensile layer 31 and wearing course 32, axially arranged in described inflation buffer strip 33 have several buffer air bags 34, it is arranged in the inflation buffer strip 33 in protection set 3 and has been provided with more buffer air bag 34, thus being also filled with other in buffer air bag 34, thus being effectively reduced the weight of whole protection set 3, thus the lighter in weight of the power cable of a group, consequently facilitating carrying, and owing to being filled with gas in buffer air bag 34, thus buffer air bag 34 has good elasticity, thus improve buffering effect.

As shown in Figure of description 1,2, described buffer air bag 34 is oval, owing to buffer air bag 34 is oval, thus easy pressurized is deformed in the middle part of buffer air bag 34, thus improve the elasticity of buffer air bag 34, thus effectively raising buffering effect.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
