Abstract
The invention discloses a medium-voltage power cable, which comprises a conductor, an insulated layer, a filling layer, and a protection layer, wherein the insulated layer coats the conductor coaxially and uniformly; the filling layer coats the insulated layer coaxially and uniformly; the protection layer coats the filling layer coaxially and uniformly; the filling layer is a metal braiding layer; and the protection layer is made of polyethylene, polyvinyl chloride or crosslinked polyethylene. Through the above mode, the medium-voltage power cable of the invention has the advantages of novel structure, small loss, large capacity, high transmission voltage, quick power transmission, stable performance, long service life, convenient and practical use, and the medium-voltage power cable can be popularized and has a wide market prospect.
Description
Technical field
The present invention relates to cable field, particularly relate to a kind of medium-pressure power cable.
Background technology
Along with the reach of science and social progress, information is transmitted in order to a part indispensable in modern production life.
The propagation of the signal of telecommunication generally needs cable or optical cable as carrier, however the general transmission voltage of existing power cable compared with low, transmission capacity is little, loss is large, is unfavorable for permanent use.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of medium-pressure power cable, by the outer surface at insulating barrier, sheath is set, considerably increase intensity and the insulativity of structure, reduce the interference such as possibility and electric power radiation that electric power punctures, novel structure, loss are little, capacity is comparatively large, transmission voltage is higher, electric power transfer is fast, stable performance, long service life, convenient and practical, have market prospects widely popularizing of medium-pressure power cable.
For solving the problems of the technologies described above, the invention provides a kind of medium-pressure power cable, comprise: conductor, insulating barrier, packed layer and sheath, the coaxial even coated described conductor of described insulating barrier, the coaxial even coated described insulating barrier of described packed layer, the coaxial even coated described packed layer of described sheath, described packed layer is wire sheathing, and the material of described sheath is polyethylene, polyvinyl chloride or crosslinked polyethylene.
In a preferred embodiment of the present invention, described conductor is cylinder copper core.
In a preferred embodiment of the present invention, described insulating barrier is polyethylene or polyvinyl chloride.
In a preferred embodiment of the present invention, the thickness of described packed layer is less than 0.5mm.
In a preferred embodiment of the present invention, the thickness of described sheath is greater than the thickness of described insulating barrier.
In a preferred embodiment of the present invention, the most high-transmission voltage of described medium-pressure power cable is less than 35kV.
The invention has the beneficial effects as follows: medium-pressure power cable of the present invention has that novel structure, loss are little, capacity is comparatively large, transmission voltage is higher, electric power transfer is fast, stable performance, long service life, the advantage such as convenient and practical, have market prospects widely popularizing of medium-pressure power cable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

The embodiment of the present invention comprises:
A kind of medium-pressure power cable, comprising: conductor 1, insulating barrier 2, packed layer 3 and sheath 4.
The coaxial even coated described conductor 1 of described insulating barrier 2, the coaxial even coated described insulating barrier 2 of described packed layer 3, the coaxial even coated described packed layer 3 of described sheath 4, described packed layer 3 is wire sheathing, flexibility and pliability good, at the outer surface of insulating barrier 2, sheath 4 is set, considerably increase intensity and the insulativity of structure, reduce the interference such as possibility and electric power radiation that electric power punctures, novel structure, loss is little, capacity is larger, transmission voltage is higher, electric power transfer is fast, stable performance, long service life, convenient and practical, the material of described sheath 4 is polyethylene, polyvinyl chloride or crosslinked polyethylene, structure is simple, lightweight, heat-resisting good, load capacity is strong, non-fusible, resistance to chemical attack, mechanical strength is high.
Preferably, described conductor 1 is cylinder copper core.
Preferably, described insulating barrier 2 is polyethylene or polyvinyl chloride.
Preferably, the thickness of described packed layer 3 is less than 0.5mm.
Preferably, the thickness of described sheath 4 is greater than the thickness of described insulating barrier 2.
Preferably, the most high-transmission voltage of described medium-pressure power cable is less than 35kV.
The beneficial effect of medium-pressure power cable of the present invention is:
One, sheath is set by the outer surface at insulating barrier, considerably increase intensity and the insulativity of structure, reduce the interference such as possibility that electric power punctures and electric power radiation, novel structure, loss is little, capacity is comparatively large, transmission voltage is higher, electric power transfer is fast, stable performance, long service life, convenient and practical;
Two, by adopting polyethylene, polyvinyl chloride or interconnected polyethylene as the material of sheath, structure simple, lightweight, heat-resisting good, load capacity is strong, non-fusible, resistance to chemical attack, mechanical strength is high.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
