Abstract
The invention discloses a copper wire shielded power cable, which comprises a conductor in the center of the cable, wherein a conductor shielding layer, an insulating layer, an insulating shielding layer, a semiconductive buffer strip, a copper wire shielding layer, a water-blocking strip, a longitudinal covering aluminum plastic armor layer, an outer protection layer, and a graphite coating layer are arranged outside the conductor in sequence. According to the invention, the coating of pitch is not required, and regular corrugated aluminum protection sleeve is not used; meanwhile, two processes are saved, manpower and materials are saved, and pollution of manufacturing for environment is reduced. The copper wire shielding layer not only can satisfy requirements of short circuit current of single-phase fault, but also can bear certain pulling force in the vertical direction; therefore, the overall performance of a product is improved.
Description
Technical field
The present invention relates to a kind of power cable, specifically a kind of copper wire shielded power cable.
Background technology
Now, China 110KV, 220KV extra-high-tension cable are widely used in electric power system.The use of extra-high-tension cable need to adapt to the actual conditions of institute's environment for use, and is also different for its requirement to cable of different environment.
The extra-high-tension cable of manufacturing at present is a pattern basically, wrapped waterstop is as vertical waterproof, weld or extrude radially waterproof of aluminium cover conduct, such product can meet the demands, but it is not high for waterproof requirement, even without the environment of waterproof, as indoor or water-less environment, manufacturing cost just seems higher like this.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of in the situation that meet instructions for use, makes the copper wire shielded power cable of low production cost.
A kind of copper wire shielded power cable of the present invention, it comprises the conductor of cable center, and the plastic-aluminum armour, outer jacket and the equadag coating that are extruded in successively the outer conductor shield of conductor, insulating barrier, insulation screen, Semi-conductive buffer band, shielding layer of copper wires, vertical bag.
Further improve, between the plastic-aluminum armour of described shielding layer of copper wires and vertical bag, waterstop is arranged.
Beneficial effect of the present invention:
1, the present invention has saved two procedures, saves human and material resources, has also reduced and has produced the pollution to environment.
2, shielding layer of copper wires can meet the requirement of single-phase fault short circuit current, also can bear the pulling force that vertical direction is certain, has improved the combination property of product, and is cost-saving.
3, the plastic-aluminum armour of vertical bag has guaranteed the structural strength of cable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of copper wire shielded power cable of the present invention, the conductor 1 that it mainly comprises cable center, set gradually conductor shield 2, insulating barrier 3, insulation screen 4, Semi-conductive buffer band 5, shielding layer of copper wires 6, waterstop 7, outer jacket 8, vertical plastic-aluminum armour 9 and the equadag coating 10 that wraps outside conductor 1.
Its operation principle: because extra-high-tension cable is higher to performance requirement; the fault single-phase short circuit current is large; the present invention utilizes brass wire shielding to bear the operation principle of single-phase fault short circuit current; Semi-conductive buffer band at the wrapped one deck 0.5mm thickness in insulation screen surface; play the effect of protection insulated wire cores, after the semi-conductive buffer belt surface carries out brass wire shielding, more wrapped one deck waterstop; after vertical bag one deck armour, directly extrude oversheath again, not only simply but also the large cost of having saved.
The present invention is from cost-saving and environmental pollution angle, lays under the condition of environment meeting extra-high-tension cable, solved the difficult problem that screen is difficult to bear the single-phase fault short circuit current, and vertical run need to bear the problem of larger pulling force simple and efficiently.In addition, the use of pitch has also been removed in cable production, has not only saved the energy, more can not produce any environmental pollution.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
