Abstract
The invention discloses an electric wire and solves the technical problem that electric wires are difficultly laid at a large span and a long distance in the prior art. The technical scheme is that: the electric wire comprises a conductive layer and an inner core layer which is positioned in the conductive layer, wherein the inner core layer consists of fiberglass-reinforced plastic (FRP) ribs. The electric wire provided by the invention has the advantages of high strength and low specific weight; the whole weight of the electric wire is greatly reduced, so that the electric wires can be easily laid at a large span and a long distance in actual application; and the aim of effectively saving electric wire laying resources is fulfilled.
Description
Technical field
The present invention relates to a kind of electric wire, particularly be a kind of span greatly, the remote electric wire of laying.
Background technology
Present high-tension bus-bar, the cable that uses, for guaranteeing its electric energy transmitting on long distance, electric wire will have the enough intensity of drawing, all adopt in electric wire inside in the prior art the method that high strength wire rope is made core is set, improve the tensile strength of electric wire, lay the requirement of transmission of electricity cable in the hope of reaching big span.But, in the middle of practical application, because adopting with the high strength wire rope is the electric wire of core, though improved the tensile strength of electric wire integral body, but because the proportion of steel wire rope is heavier, significantly increase problem with regard to the weight that causes electric wire integral body, finally cause being difficult to realize the purpose of big span laying transmission of electricity cable.
The present invention is just in order to solve above-mentioned technical problem, and proposed a kind of new technical scheme.
Summary of the invention
The objective of the invention is to cause the electric wire overall weight significantly to increase causing to realize big span to lay the technical problem of transmission of electricity cable because of adopting steel wire rope to make core, and the electric wire of the laying of span greatly of a kind of tensile strength height, light specific gravity is provided in order to solve existing electric wire.
In order to solve the problems of the technologies described above, the present invention mainly takes following technical scheme:
A kind of electric wire comprises conductive layer and the inner sandwich layer that is positioned at described conductive layer inside, and described inner sandwich layer is the FRP muscle.
As an optimal technical scheme of the present invention, described FRP muscle inside is provided with Fibre Optical Sensor.
Further, described FRP muscle is formed by high molecular polymer and fiber composite.
Further, described high molecular polymer is at least a in unsaturated-resin, vinylite, epoxy resin, polyethylene, polypropylene and the polyester.
Further, described fiber is at least a in polypropylene fibre, polyester fiber, carbon fiber, acrylic fiber, glass fibre and the basalt fibre.
As another optimal technical scheme of the present invention, described Fibre Optical Sensor is fiber-optic grating sensor, distributed fiberoptic sensor, draw in the halation fiber sensor any one.
As another optimal technical scheme of the present invention, described conductive layer is made by copper, aluminum or aluminum alloy.
Adopt electric wire provided by the invention, have the advantage of intensity height, light specific gravity, the weight of electric wire integral body is declined to a great extent.According to measurement, under the identical situation of specification, the weight of FRP muscle is 1/4th of steel wire rope weight, adopting the FRP muscle is that the electric wire that inner core is made is that the electric wire that core is made has significantly reduction on weight than adopting steel wire rope, can be in the middle of the application of reality, realize big span, remote laying wire easily, finally reach the purpose of effective saving laying wire resource.
