Abstract
The utility model relates to a double-layer super-flexible power transmission cable which is suitable for cable connection of wind power control system and drag or servo-actuated power transmission systems under various harsh environments. The double-layer super-flexible power transmission cable comprises bare-copper conductive groups formed by twisting a plurality of bare copper wires into bundles, a polyethylene insulating layer and a crosslinked elastomer composite sheath, wherein the plurality of bare-copper conductive groups are twisted into bundles, and a high-pressure thin-wall polyethylene insulating layer and a crosslinked elastomer composite sheath are sequentially extruded outside the bundles. The cable is excellent in mechanical performance, flexibility, insulating layer performance, and wear resistance, and high in cost performance. The cable is convenient for processing and high in universality and production efficiency.
Description
Technical field
The utility model relates to the super gentle power transmission cable of a kind of bilayer, is used for the flexible dynamic transmission system, and the main frequent crooked cable of mobile use of using connects.Be applicable to drag under wind power control system and various adverse circumstances or the equipment inner cable of servo-actuated electrical power transmission system connects.
Background technology
In world today's productive life, the electric automatization degree is more and more higher, and the utilization of electric energy relates to the every aspect of national economy.Electric wire as the basic material of electric energy transmitting is of a great variety, and the special cable design that is applied to different occasions is particularly important.The flexible life-span of high flexibility, long novel cable arose at the historic moment.This patent is based on this background condition, and development and Design is completed under technical staff's effort.
Summary of the invention
In view of the extensive extension of power transmission cable market prospect of the application, the utility model provides a kind of bilayer super gentle power transmission cable.Can reach the user fully from the design of choosing structure of composition material and expect requirement.
The utility model is for reaching above-mentioned purpose of design, the technical scheme that adopts is: the super gentle power transmission cable of a kind of bilayer, it is characterized in that: comprise bare copper conductor group, polyethylene layer, cross-linking elasticity composite material sheath that the stranded bunchy of several bare copper wires consists of, the stranded bunchy of the described bare copper conductor group of array extrudes successively one deck high-pressure thin-wall polyethylene layer, extrudes one deck cross-linking elasticity composite material sheath outside it.
The beneficial effects of the utility model are: 1, superior top-ranking mechanical performance and the high flexibility of cable: bunchy of the multiply essence thin bare copper wire of strand is stranded, and dimensionally stable adopts the stranded flexibility of meticulous copper wire fine pith greatly to improve.Stable mechanical performance is not yielding.2, insulating barrier excellent performance: import cross-linking type heigh pressure resisting thin-walled polyethylene ductility is good, and mechanical strength is high, and abrasion performance is good, is suitable for thin-walled and extrudes, and cable dimension obviously reduces than mill run.After Study of Crosslinking of Polyethylene by Irradiation, mechanical strength and thermal endurance class improve, and little because of the size small-bend radius simultaneously, the cable flexibility improves.3, good resistance to wear: oversheath adopts the cross-linking radiation elastic composite, and soft resistance to wear improves, and is suitable for frequent mobile cable and connects.4, good cost performance: cable adopts bunchy of conductor stranded, and thin-walled design is adopted in insulation, and oversheath adopts the cross-linking elasticity composite material.Can substitute similar rubber sheathed cable, the cost ratio rubber cable is cheaply a lot, and is cost-effective, and cost performance is obvious.5, easy to process: use the general electrical cable-making apparatus can production and processing, highly versatile, production efficiency is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Consist of 480 ∕ 0.25(cross section 25mm with conductor
2) a cable be example.
As shown in Figure 1, this cable comprises bare copper conductor group 1, polyethylene layer 2, the cross-linking elasticity composite material sheath 3 of 480 stranded formations of the thin bare copper wire of 0.25mm diameter.Work flow is that at first 480 bare copper wires with bare copper conductor group 1 are divided into 20 groups, and every group is comprised of 24 single bare copper wires, 20 groups of wire harness shallow bids by the sequence of strand winder noseplate after disposable bundle strand, consist of bare copper conductor group 1; Then extrude successively the cable finished product of layer of polyethylene insulating barrier 2, one deck cross-linking elasticity composite material sheath 3 formation cable size 12mm outside conductor group 1.Polyethylene layer 2 thickness are 0.7mm.
Above-mentioned polyethylene layer (2) adopts high pressure resistant polythene material and processes by cross-linking radiation; Above-mentioned cross-linking elasticity composite material sheath (3) adopts the cross-linking elasticity nanocrystal composition of high abrasion resistance.
Although the above is described preferred enforcement of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the execution mode of above-mentioned concrete specification; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of specification products, within these all belong to protection range of the present utility model.
