Abstract

The utility model relates to the technical field of electric power fittings, and aims to provide a power cable with high tensile strength and good insulating property. The power cable comprises at least one inner core prepared by steel wire, an external layer consisting a plurality of intertwisted aluminium conductors tightly arranged around the inner core, and an insulating layer wrapping the external layer. The utility model has the advantage that aluminium wires are intertwisted around the steel core to increase tensile strength of the line, and the insulating layer is wrapped on the external layer to increase insulating property of the line. The utility model has characteristics of simple structure, convenience for erection and maintenance, large tensile strength, good insulating property and capability of enlarging a tower rod distance.

Description

A kind of power cable
Technical field
The utility model relates to the electric armour clamp technical field, is specifically related to a kind of power cable.
Background technology
What generally use in city and rural area transmission line at present is aluminium cable, but in transmission line, has certain span owing between the tower bar, and common aluminium cable is because tensile property is bad, often in transmission line, need to lay more tower bar, the wasting of resources is more serious, and its insulating properties of aluminium cable is bad, has brought hidden danger for people's life, therefore needs transmission line to have tensile property and insulation property preferably in the circuit transmission.
The utility model content
The purpose of this utility model is for having solved above-mentioned existing technical disadvantages, and the utility model provides a kind of tensile strength height, the power cable of good insulation preformance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of power cable comprises the inner core made by the steel material, closely is arranged in skin around the inner core, wraps up outer field insulating barrier by stranded mode by some aluminum conductors.
Preferably: described inner core is galvanized steel wire.
Preferably: described steel wire quantity is 1.
Preferably: described aluminum conductor quantity is 6.
Preferably: described insulating barrier is polyvinyl chloride.
Useful technique effect of the present invention is: in the technical solution of the utility model, by aluminum steel being stranded in steel core on every side to increase the tensile strength of circuit, outer wrap insulate layer to be to increase the insulating properties of circuit, have simple in structure, set up with easy to maintenance, tensile strength big, the tower pole clearance is from characteristics such as scalable, good insulating.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the first embodiment cross-sectional view of the present utility model;
Fig. 3 is the second embodiment cross-sectional view of the present utility model.
Among the figure: 1, inner core, 2, skin, 3, insulating barrier, 4, steel wire, 5, aluminum conductor.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 and Figure 2, as first kind of specific embodiment of the present utility model.
A kind of power cable comprises inner core 1, skin 2, insulating barrier 3; Inner core 1 is a steel wire 4, the preferred galvanized steel wire of present embodiment, obviously also can be high-carbon steel wire or other steel wires 4, outer 2 for closely being arranged in inner core 16 aluminum conductors 5 on every side by stranded mode, inner core 1 is that many steel wires 4 are when stranded, the direction of lay of the direction of lay of inner core 1 and skin 2 is opposite, and the rotating torque of each layer generation is cancelled out each other when twisted wire is stressed, and the steel wire 4 of inner core 1 and outer 2 aluminum conductor 5 are rotated and the pine thigh to a direction.Steel wire 4 is the load spare of this power cable, and aluminum conductor 5 mainly works to transmit electric energy.Insulating barrier 3 parcel is outer 2, and insulating barrier 3 is made of polyvinyl chloride, has the good insulation performance to guarantee transmission line.
As shown in Figure 3, as second kind of specific embodiment of the present utility model.
A kind of power cable, inner core 1 adopts three steel wire 4 stranded forming, other and first kind of embodiment are consistent, when tower bar span increases, when needing transmission line to have higher tensile property, also can twist together by many steel wires 4, in the middle of reality, can adjust the quantity of steel wire 4 and aluminum conductor 5 according to the span of tower bar.Described embodiment only is the utility model part embodiment, rather than whole embodiment.
In sum: at the utility model by aluminum steel being stranded in around the steel core to increase the tensile strength of circuit, outer wrap insulate layer is to increase the insulating properties of circuit, the utlity model has tensile strength height, good insulation preformance, tower pole clearance from characteristics such as scalable, and the utility model simple in structure, set up with easy to maintenance, be conducive on the outskirts of a town the laying with the rural area transmission line.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
