Description

A kind of copper cover aluminum zirconium alloy cable

Technical field

The present invention relates to a kind of copper cover aluminum zirconium alloy cable.

Background technology

The metallic substance of occurring in nature conduction the best is silver, is then copper and aluminium.Because silver belongs to noble metal, can not use as industrial cable on a large scale, therefore copper just becomes the conductive metallic material be most widely used.Produce cable and always make inner wire with fine copper, the weight of copper accounts for 70 ~ 75% of cable gross weight.Conducting electricity very well of copper, toughness is good, but cost ratio aluminium is more expensive, also more rare.Under the situation that international, domestic amount of copper consuming constantly rise, copper resource gets over shortage, adds human factor, copper valency rises violently, high, form a series of rise in price reflection, force cable industry actively to seek new conductor material and carry out the inner wire that alternative pure copper wire makes cable.

Along with the development of science and technology, the use of cable is more and more extensive.At present, the cable of at least two stranded similar ropes normally often organized by cable by several or several groups of wires, often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the tectum of high-insulation, heart yearn great majority in its cable are copper wires, owing to adopting the design of copper, its price is costly higher with density, and oxidation is easily caused for a long time in the surface of copper, cause thermoplastic property difference and intensity is low, because cable cross-sections strengthens, for establishing circuit to rebuild, difficulty of construction is large, and expense is large.

Summary of the invention

The technical problem to be solved in the present invention is: overcome the deficiency in prior art, and provide a kind of mechanicalness, the electric conductivity that effectively improve cable, its tensile strength, anti-resistivity are high, improves the copper cover aluminum zirconium alloy cable of erosion resistance.

The technical solution adopted for the present invention to solve the technical problems is: a kind of copper cover aluminum zirconium alloy cable, there is core body, the surface spraying of described core body has layers of copper, core body is that aluminium Zirconium alloy material is made, and wherein aluminium zirconium alloy line by the weight percent of component is: the silicon of 0.03-0.05%, the manganese of 0.5-1.0%, the copper of 0.8-1.2%, the titanium of 0.05-0.1%, the niobium of 0.03-0.05%, the vanadium of 0.3-0.35%, the boron of 0.003-0.005%, the nickel of 0.1-0.3%, the chromium of 0.1-0.3%, the zirconium of 0.1-0.3%, the tin of 0.05-0.08%, the zinc of < 0.001%, the gallium of < 0.001%, the bismuth of 0.003-0.005%, surplus is aluminium, and zirconium can improve resistance toheat, intensity and resistivity, reduce unit elongation, and to resistance toheat and resistivity effects remarkable especially, but affect not remarkable on intensity and unit elongation, do not add the common aluminum steel of zirconium after 90 DEG C and 230 DEG C are incubated 3 hours, tensile strength survival rate is respectively 96% and 83%, and the tensile strength survival rate of zirconium alloy line is respectively 100% and 96%.

Further, described DC resistivity≤0.0295 Ω mm ²/ m, tensile strength>=170MPa, elongation>=12%, density is 3.51 ~ 3.60g/cm ³, very large to resistance toheat and resistivity effects through bracing wire technique, cold-drawn machining deformation rate and cold-drawn speed larger, subgrain boundary size is less, and the intensity of line, high-temperature capability and resistivity are higher, and unit elongation is lower.

Further, described DC resistivity is 0.02930 Ω mm ²/ m, tensile strength is 190MPa, elongation 13%, and density is 3.55g/cm ³, the high-quality alumite bar that its high-temperature capability survival rate is greater than 95%, and steady quality.

The invention has the beneficial effects as follows: structure of the present invention is simple, and effectively improve the mechanicalness of cable, electric conductivity, its tensile strength, anti-resistivity are high, improve erosion resistance, strengthen the stability of its intensity and raising resistivity, there is good conductivity simultaneously, and save copper material, intensity is higher, heat resisting temperature is high, effectively solves increase-volume problem, long service life, not easily there is the phenomenons such as short circuit, improve safety coefficient.
