Abstract
The utility model discloses a semicircular-conductor low-voltage dual-core electric power cable. Two copper-core conductors coated with polyvinyl chloride (PVC) insulating layers are arranged inside the cable, and a lapping layer, a shielding layer, another lapping layer and a flame retardant PVC outer sheath are sequentially wrapped on the outer layer of the cable from inside to outside. The electric power cable is characterized in that the cross section of each of the copper-core conductors is semicircular. On the premise of guaranteeing that all performances of the cable meet the national standard of GB/T12706-2008, shapes of the conductors of the cable are changed, the conductors (main cores) are combined more closely, so that the outer diameter of the cable is reduced, and difficulty in package, transport and laying of the cable is reduced to some degree.
Description
Technical field
The utility model relates to power cable, particularly, is a kind of semicircular conductor low pressure two core power cables.
Background technology
In meeting the power cable of standard GB/T12706-2008, for conductor (master core) nominal cross 〉=50mm
2Twin core cable, usually the outer again mode of production of wrapping up in lapping layer, insulating barrier etc. after the round conductors of two outer plating insulating barriers are gathered in employing, its shortcoming is that the space is bigger between the conductor, compactness is poor, cause the external diameter of finished product to increase, problems such as packing, transport and lay has all been increased difficulty.
The utility model content
The purpose of this utility model is to provide a kind of semicircular conductor low pressure two core power cables, it is by the change to conductor shape, guaranteeing that all performances of product all meet under the prerequisite of standard GB/T12706-2008, make conductor (master core) combination each other tightr, the finished product external diameter reduces.
Concrete technical scheme of the present utility model is:
A kind of semicircular conductor low pressure two core power cables, inside is the copper core conductor of two outer plating PVC insulating barriers, skin is enclosed with lapping layer, screen, lapping layer and flame-proof PVC oversheath from inside to outside successively, and the cross sectional shape that is characterised in that described copper core conductor is for semicircle.
Semicircular conductor low pressure two core power cables of the present utility model, because the cross sectional shape of copper core conductor changes over semicircle, two conductors are just formed a disc together, are bonded to each other closely, the space is minimum, is guaranteeing copper core conductor (master core) nominal cross (〉=50mm
2) under the constant prerequisite, reduced the external diameter of finished product greatly, make packing, the difficulty of problem such as transporting and laying all decrease, and all performances all meet standard GB/T12706-2008.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a composition structural representation of the present utility model.
Among the figure:
1, copper core conductor; 2, PVC insulating barrier; 3, lapping layer; 4, screen; 5, lapping layer; 6, flame-proof PVC oversheath.
Embodiment
As shown in Figure 1, provided an embodiment of semicircular conductor low pressure two core power cables described in the utility model, its inside is the copper core conductor 1 of two outer plating PVC insulating barriers 2, skin is enclosed with lapping layer 3, screen 4, lapping layer 5 and flame-proof PVC oversheath 6 from inside to outside successively, and the cross sectional shape that is characterised in that described copper core conductor 1 is for semicircle.Semicircular conductor low pressure two core power cables of present embodiment are bonded to each other closely because the cross sectional shape of copper core conductor 1 changes over semicircle, and two conductors are just formed a disc together, and the space is minimum, are guaranteeing copper core conductor 1 nominal cross (〉=50mm
2) under the constant prerequisite, reduced the external diameter of finished product greatly, make packing, the difficulty of problem such as transporting and laying all decrease, all performances all meet standard GB/T12706-2008.
Claims (1)
