Abstract
The present utility model discloses a high-strength power cable. The power cable comprises an outermost sheath, a conductor arranged inside the sheath and an insulation layer wrapped outside the conductor, and a steel wire is arranged inside the conductor. In the cable, when a conductive core is manufactured, a high-strength steel wire or a twisted steel wire is added on the inner layer of the conductor, thus the conductive core itself can endure large snapping force, strength and snapping force of the cable itself can be enhanced, the manufacturing technology is simple, and the high-strength power cable can be used in wind power generation, high mountains and valleys and other occasions requiring high-strength cables.
Description
Technical field
The utility model belongs to the power cable technical field, is specifically related to a kind of high strength electric power cable.
Background technology
Existing power cable generally is made up of conductor, insulating barrier, sheath, and the asbestos charges are set between sheath and the conductor, and the cable intensity of this structure is little, pull-off force is lower, and lay on only suitable plane.Improve the cable pull-off force, now mostly be to adopt the wire armoring structure, the utility model patent of patent No. CN201120220963.4 discloses a kind of high-strength cable; Comprise the insulating barrier that plurality of conductors is outer with being coated on every conductor; Single conductor and insulating barrier are formed core, are coated with lapping layer at core, outside lapping layer, are provided with oversheath; It is characterized in that, between lapping layer and oversheath, be provided with the galvanized steel strip protective layer.That this structure is not only made is numerous and diverse, need large-scale special equipment, efficient is low, cost is high, and the cable deadweight increases severely, and not being suitable for wind power generation, high mountain gorge etc. only needs high strength not need the occasion of high protection to use.
Summary of the invention
The utility model provides a kind of manufacturing process simple, the novel electric power cable that intensity is big, pull-off force is high in order to solve the problem that prior art exists.
The technical scheme of the utility model: a kind of high strength electric power cable comprises outermost sheath, the conductor that is provided with in the sheath and be coated on the outer insulating barrier of conductor, conductor set inside steel wire.
The asbestos charges are set between said sheath and the conductor.
Said number of conductors is 3.
Said steel wire is that strands forms.
The technique effect of the utility model: the cable of the utility model is when making conductor wire core; Add high-tensile steel wires or stranded steel wire at the conductor internal layer; Make conductor wire core itself just can bear bigger pull-off force; Thereby improved the intensity and the pull-off force of cable itself, its manufacturing process is simple, needs the occasion of high-strength cable applicable to wind-power electricity generation, high mountain gorge etc.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of high strength electric power cable comprises outermost sheath 1, the conductor 2 that is provided with in the sheath 1 and be coated on the outer insulating barrier 3 of conductor 2, said conductor 2 set inside steel wires 4; Between sheath 1 and the conductor 2 asbestos charges 5 are set; Conductor 2 quantity are 3; Steel wire 4 forms for strands.
