Abstract

The utility model relates to an electric wire with low cost, which comprises an iron wire inner core, and a nonferrous metal-plating layer with high electric conductivity arranged outside the iron wire, wherein the thickness of the nonferrous metal-plating layer accounts for 5% to 12.5% of the total diameter of the electric wire. About 70% of nonferrous metal material is saved on the premise of not impacting electric conductivity of the electric wire, so the electric wire is favorable for saving resource and protecting environment. Since the melting point of the nonferrous metal materials, such as copper, aluminum and the like, is lower than that of the iron wire, the nonferrous metal materials can be plated on the outer surface of the iron wire easily, namely, the process is simple and good in practicability. Simultaneously, the overall strength of the electric wire and be enhanced owing to the higher strength of the iron wire, thus the service life of the electric wire is prolonged.

Description

A kind of low-cost electric wire

Technical field

The utility model relates to a kind of electric wire, is specifically related to a kind of low-cost electric wire.

Background technology

At present, the electric wire that electric power, telecommunication system generally use, cable conductor material mostly are copper or aluminium, because the price of metallic copper, aluminium is comparatively expensive, make that the cost of high-quality electric wire is very high.Along with the continuous growth of world's non-ferrous metal consumption and the shortage day by day of mineral resources, cause the price of copper, aluminium rapidly to go up, product that diameter is nonconforming, sectional area is not up to standard and the low-quality goods that uses composition brass, aluminium have appearred on the electric wire market.Though someone once proposed to use cheap metal to come Alloy instead of Copper, aluminium, this simple replacement can influence the serviceability of electric wire, and effect is very undesirable.

The utility model content

The utility model has proposed a kind of non-ferrous metal layer that passes through to electroplate at the outer surface of iron wire high conductivity at the deficiencies in the prior art, has the material cost of saving electric wire, and does not influence the low-cost electric wire of wiring conductive efficient.

The technical solution of the utility model is as follows:

A kind of low-cost electric wire is characterized in that: it comprises an iron wire inner core, and the coating that the high conductivity non-ferrous metal is set outside described iron wire, and the thickness of described coating is 5%～12.5% of electric wire overall diameter.

The radial thickness of described coating is 7.5%～10% of an electric wire overall diameter.

Described high conductivity non-ferrous metal is copper or aluminium.

The material of described iron wire is a pure iron.

Described coating is provided with protective layer outward.

Described protective layer is baking vanish or plastic film.

Technique effect of the present utility model is as follows:

Electric wire of the present utility model is owing to electroplate the non-ferrous metal of high conductivity in the iron wire outside; under the prerequisite of the electrical efficiency that does not influence electric wire; if the thickness of coating is 7.5%～10% of electric wire overall diameter; then can save about nonferrous materials of about 70%, help economizing on resources and environmental protection.

Because the fusing point of metal materials such as copper, aluminium is lower than iron wire, thereby can be plated in the outer surface of iron wire easily, technology is simple, is easy to realize.Simultaneously because the intensity of iron wire is higher, thereby can improve the electric wire integral intensity, the useful life of extending wire.

Embodiment

Below in conjunction with accompanying drawing the utility model is described.

As shown in Figure 1 and Figure 2, the utility model is coated with coating 2 in iron wire 1 surface electrical that thickness does not wait, and the material of iron wire 1 is a pure iron, and the material of coating 2 is high conductivity non-ferrous metals such as copper or aluminium.Wherein the radial thickness of coating 2 is 5%～12.5% of electric wire overall diameters, and the radial thickness of coating 2 can be preferably 7.5%～10% of electric wire overall diameter.And can as required outside coating 2, protective layer can be set as required, protective layer can be baking vanish or plastic film etc.

When alternating current passed through electric wire of the present utility model, alternating current was in the inner skin effect that produces of electric wire, and the feasible nearly electric wire surface current density that heals is big more.The frequency of alternating current is high more, and skin effect is remarkable more.When the very high electric current of frequency during by lead, can think that electric current only flows through in very thin one deck on conductive line surfaces, the core of lead does not almost have electric current to pass through, thereby can replace this core with iron wire 1.

Though skin effect is not so good as strong to the effect of alternating current to galvanic effect, but iron wire 1 also is a conductor in the electric wire, and the conductance of iron wire 1 is lower than copper or aluminium, electronics can be selected the high channel flow of conductance by the light of nature in electric wire, so electric wire of the present utility model also can be applicable in the DC circuit.

Should be pointed out that the above embodiment can make those skilled in the art more fully understand the utility model and create, create but limit the utility model never in any form.Therefore; although this specification is created the utility model with reference to drawings and Examples and is had been described in detail; but; those skilled in the art are to be understood that; still can create the utility model and make amendment or be equal to replacement; in a word, all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the utility model creation, and it all should be encompassed in the utility model and create in the middle of the protection range of patent.
